[Patch] x86, ia64, efifb: Move boot_vga fixup from pci to vgaarb

[Patch] x86, ia64, efifb: Move boot_vga fixup from pci to vgaarb

[Bruno Prémont]

With commit b4aa0163056b6c70029b6e8619ce07c274351f42 Matthew Garret
introduced a efifb vga_default_device() so that EFI systems that do not
load shadow VBIOS or setup VGA get proper value for boot_vga PCI sysfs
attribute on the corresponding PCI device.

Xorg is refusing to autodetect devices when boot_vga=0 which is the case
on some EFI system (e.g. MacBookAir2,1). Xorg detects the GPU and finds
the dri device but then bails out with "no devices detected".

With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete
while having native drivers for the GPU also makes selecting
sysfb/efifb optional.

Remove the efifb implementation of vga_default_device() and initialize
vgaarb's vga_default_device() with the PCI GPU that matches boot
screen_info in pci_fixup_video() [x86 and ia64 pci_fixup_video merged
into common function in vgaarb.c].

Other architectures with PCI GPU might need a similar fixup.

Note: If CONFIG_VGA_ARB is unset vga_default_device() is only available
      as a stub that returns NULL, making this adjustment insufficient.
      In addition, with the merge of x86/ia64 fixup code, this would
      also result in disabled fixup.
      Unsetting CONFIG_VGA_ARB requires CONFIG_EXPERT=y though.

This is ported to changes in pci/fixup.c that landed in 3.15-rcs.

Is this fine to go in, if so who will take it?

I got no feedback on my last respin (on top of 3.14 a couple of weeks ago,
which added moving the ia64 pci boot_vga fixup).
I've been running this revision for a week or so on 3.15-rc kernels here
(mostly EFI-enabled system, the mentioned MBA as wells as non-Apple systems
where the patch was not required).

I think there's an emerging convention to use reference commits as

    b4aa0163056b ("efifb: Implement vga_default_device() (v2)")

for this case.  Also, s/Garret/Garrett/.

I think it would be good to split this into two patches:

  1) Merge the x86 and ia64 pci_fixup_video() implementations.  This should
  have no functional change at all.

  2) Whatever else you need to actually fix the bug.  This will be much
  smaller, and the actual bug fix will be easier to see.

It would also be nice to have a URL for a bugzilla or mailing list report
of the problem, where there might be dmesg and/or Xorg logs.

This sounds like it might be applicable for the stable kernels.  If so, you
probably should order these so the small bug-fix comes first (even though
this may mean applying the same bugfix for x86 and ia64), and the merge
second.  That way the fix can be applied to the stable kernels without the
merge.

I'm not quite sure what this means, or if this is hint that something is
still wrong even with this patch.  Do you mean that if CONFIG_VGA_ARB is
unset, something still doesn't work?

Maybe this will become obvious to me when you split up the patch.

I have a patch in my pci/pci_is_bridge branch that will conflict with this,
but I'll take care of sorting that out.  You can continue to base your
patch on v3.15-rc1 or whatever you're using.

It looks like pci_fixup_video() is only called as a quirk, so there aren't
going to be random callers that will look for information at this
declaration.

I think there's an emerging convention to use reference commits as
<12-char-SHA1> ("subject"), i.e.,

    b4aa0163056b ("efifb: Implement vga_default_device() (v2)")

for this case.  Also, s/Garret/Garrett/.

I think it would be good to split this into two patches:

  1) Merge the x86 and ia64 pci_fixup_video() implementations.  This should
  have no functional change at all.

  2) Whatever else you need to actually fix the bug.  This will be much
  smaller, and the actual bug fix will be easier to see.

It would also be nice to have a URL for a bugzilla or mailing list report
of the problem, where there might be dmesg and/or Xorg logs.

This sounds like it might be applicable for the stable kernels.  If so, you
probably should order these so the small bug-fix comes first (even though
this may mean applying the same bugfix for x86 and ia64), and the merge
second.  That way the fix can be applied to the stable kernels without the
merge.

I'm not quite sure what this means, or if this is hint that something is
still wrong even with this patch.  Do you mean that if CONFIG_VGA_ARB is
unset, something still doesn't work?

Maybe this will become obvious to me when you split up the patch.

I have a patch in my pci/pci_is_bridge branch that will conflict with this,
but I'll take care of sorting that out.  You can continue to base your
patch on v3.15-rc1 or whatever you're using.

I would fold this information into the comment at the function definition.
It looks like pci_fixup_video() is only called as a quirk, so there aren't
going to be random callers that will look for information at this

This means that if someone unsets CONFIG_VGA_ARB (he need to set CONFIG_EXPERT
to do so) the fixup will not happen at all.

Without fixup the systems that need to set the IORESOURCE_ROM_SHADOW
flag will not have it, and boot_vga pci device attribute will be 0
more often as well.

Moving the unified function somewhere else than vgaarb.c would fix the new
IORESOURCE_ROM_SHADOW fixup dependency on VGA_ARB, though not prevent the
issue I try to fix as vga_default_device() always returns NULL without VGA_ARB.

One possible location would be drivers/pci/quirks.c.

[PATCH 2/2] x86, ia64: Merge common vga fixup code

[Bruno Prémont]

The fixup code for PCI VGA devices in ia64 and x86 is mostly identical.

Merge it into a single function called from both sides.

The common code is moved to vgaarb.c which makes in dependant on
CONFIG_VGA_ARB.

[PATCH 1/2] x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()

[Bruno Prémont]

With commit b4aa0163056b ("efifb: Implement vga_default_device() (v2)")
Matthew Garrett introduced a efifb vga_default_device() so that EFI
systems that do not load shadow VBIOS or setup VGA get proper value for
boot_vga PCI sysfs attribute on the corresponding PCI device.

Xorg is refusing to detect devices when boot_vga=0 which is the case on
some EFI system (e.g. MacBookAir2,1). Xorg detects the GPU and finds
the dri device but then bails out with "no devices detected".

Note: When vga_default_device() is set boot_vga PCI sysfs attribute
reflects its state. When unset this attribute is 1 whenever
IORESOURCE_ROM_SHADOW flag is set.

With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete
while having native drivers for the GPU also makes selecting
sysfb/efifb optional.

Remove the efifb implementation of vga_default_device() and initialize
vgaarb's vga_default_device() with the PCI GPU that matches boot
screen_info in pci_fixup_video().

Something went wrong here.  It seems like the [2/2] patch should have
been [1/2], and this one should be [2/2].  And this one modifies both
arch/ia64/pci/fixup.c and arch/x86/pci/fixup.c, but the other patch
mostly combines them, so I don't see how this one applies.

And there were unrelated (trivial) changes to these files, so they
need to be rebased to v3.16-rc1.  I'd take care of the rebase, but
I don't understand the other stuff I mentioned.

Something went wrong here.  It seems like the [2/2] patch should have
been [1/2], and this one should be [2/2].  And this one modifies both
arch/ia64/pci/fixup.c and arch/x86/pci/fixup.c, but the other patch
mostly combines them, so I don't see how this one applies.

And there were unrelated (trivial) changes to these files, so they
need to be rebased to v3.16-rc1.  I'd take care of the rebase, but
I don't understand the other stuff I mentioned.

I ordered both patches the other way around from your explicit ordering
proposal following the stable kernel suggestion following it.

My patch 1/2 fixes the encountered issue and is the one that may go
stable while my patch 2/2 performs unification of common code.
The unification will need to be placed somewhere else than in vgaarb.c
if one wants to keep current fixup working with CONFIG_VGA_ARB=n.

if one wants to keep current fixup working with CONFIG_VGA_ARB=n.

Quite a few people trip over this issue, apparently concentrated on
Apple Macs (EFI) with Nvidia graphics.

It has shown up in at least two bugzilla reports (as side-issue):
  https://bugs.freedesktop.org/show_bug.cgi?id=58556#c16
  https://bugs.freedesktop.org/show_bug.cgi?id=76732#c34

My initial report and discussion on freenode, #nouveau:
  http://people.freedesktop.org/~cbrill/dri-log/?channel=nouveau&date=2013-11-23
followed by initial patch proposal:
  http://permalink.gmane.org/gmane.comp.video.dri.devel/95943

>From today on #nouveau:
  Tested-by: Anibal Francisco Martinez Cortina <linuxkid.zeuz@gmail.com>

As reported on #nouveau, every now and then someone trips over this issue
and falls back to enabling efifb so X server accepts to start without
explicit configuration.

It would also be worth to add for first patch:

[PATCH 1/2 v2] x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()

[Bruno Prémont]

With commit b4aa0163056b ("efifb: Implement vga_default_device() (v2)")
Matthew Garrett introduced a efifb vga_default_device() so that EFI
systems that do not load shadow VBIOS or setup VGA get proper value for
boot_vga PCI sysfs attribute on the corresponding PCI device.

Xorg is refusing to detect devices when boot_vga=0 which is the case on
some EFI system (e.g. MacBookAir2,1). Xorg detects the GPU and finds
the dri device but then bails out with "no devices detected".

Note: When vga_default_device() is set boot_vga PCI sysfs attribute
reflects its state. When unset this attribute is 1 whenever
IORESOURCE_ROM_SHADOW flag is set.

With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete
while having native drivers for the GPU also makes selecting
sysfb/efifb optional.

Remove the efifb implementation of vga_default_device() and initialize
vgaarb's vga_default_device() with the PCI GPU that matches boot
screen_info in pci_fixup_video().

[PATCH 1/2 v2] x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()

[Bruno Prémont]

With commit b4aa0163056b ("efifb: Implement vga_default_device() (v2)")
Matthew Garrett introduced a efifb vga_default_device() so that EFI
systems that do not load shadow VBIOS or setup VGA get proper value for
boot_vga PCI sysfs attribute on the corresponding PCI device.

Xorg is refusing to detect devices when boot_vga=0 which is the case on
some EFI system (e.g. MacBookAir2,1). Xorg detects the GPU and finds
the dri device but then bails out with "no devices detected".

Note: When vga_default_device() is set boot_vga PCI sysfs attribute
reflects its state. When unset this attribute is 1 whenever
IORESOURCE_ROM_SHADOW flag is set.

With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete
while having native drivers for the GPU also makes selecting
sysfb/efifb optional.

Remove the efifb implementation of vga_default_device() and initialize
vgaarb's vga_default_device() with the PCI GPU that matches boot
screen_info in pci_fixup_video().

[PATCH 2/2 v2] x86, ia64: Merge common vga fixup code

[Bruno Prémont]

The fixup code for PCI VGA devices in ia64 and x86 is mostly identical.

Merge it into a single function called from both sides.

The common code is moved to vgaarb.c which makes in dependant on
CONFIG_VGA_ARB.

[PATCH 2/2 v2] x86, ia64: Merge common vga fixup code

[Bruno Prémont]

The fixup code for PCI VGA devices in ia64 and x86 is mostly identical.

Merge it into a single function called from both sides.

The common code is moved to vgaarb.c which makes in dependant on
CONFIG_VGA_ARB.

I just tried to run the latest kernel.  It failed to boot and git
bisect points to this commit (MacBookPro10,1 with Nvidia&Intel
graphics).

The (now removed) code in efifb_setup did always set default_vga, even
if it had already been set earlier. The new code in pci_fixup_video
runs only if vga_default_device() is NULL. Removing the check fixes
the regression.


The following calls to vga_set_default_device are made during boot:

vga_arbiter_add_pci_device -> vga_set_default_device(intel)
pci_fixup_video -> vga_set_default_device(intel) (there are two calls
in pci_fixup_video, this one is the one near "Boot video device")
pci_fixup_video -> vga_set_default_device(nvidia) (from the "Does
firmware framebuffer belong to us?" loop, only if I remove the check)

vga_arbiter_add_pci_device chooses intel simply because it is the
first device. Next pci_fixup_video(intel) sees that it is the default
device, sets the IORESOURCE_ROM_SHADOW flag and calls
vga_set_default_device again. And finally (if the check is removed)
pci_fixup_video(nvidia) sees that it owns the framebuffer and sets
itself as the default device which allows the system to boot again.

Does setting the ROM_SHADOW flag on (possibly) the wrong device have
any effect? Maybe we should also move this whole detection logic to
some earlier stage to make sure that the default device is correct
from the beginning and doesn't change?

Yes it does. Removing the line changes a long standing
i915 0000:00:02.0: Invalid ROM contents
into a
i915 0000:00:02.0: BAR 6: can't assign [??? 0x00000000 flags
0x20000000] (bogus alignment).

The first is logged at KERN_ERR and the second one only at KERN_INFO.
We are making progress.

How does your system behave if you change vga_arbiter_add_pci_device()
not to set vga_set_default_device() with the first device registered?

That is remove the 
#ifndef __ARCH_HAS_VGA_DEFAULT_DEVICE
code block in vga_arbiter_add_pci_device().

How did your system behave in the past if you did not enable efifb?

The system does not boot.  The Intel device is still set as the
default device in pci_fixup_video (near "Boot video device") and
prevents the nvidia device (which is initialized later) from becoming
the default one.

I don't think that I ever did not enable efifb. It seems to have been
around for quite a while?

The question here is if you system just refuses to boot as well.

The aim of my patch is to make system work (properly) when efifb is not used
(why use efifb if built-in drm drivers handle the GPU(s)?)

If you decided to replace efifb with platform-framebuffer+simplefb/simpledrm
you would probably see the same issue as that would be no efifb as well.

The presence of efifb should not be mandatory for successfully booting
and running Xorg.

How does you system behave with below patch on top of Linus tree?

I have just tested 3.16 without FB_EFI and it refuses to boot as well.

[PATCH 0/2] x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()

[Bruno Prémont]

This series improves on commit 20cde694027e (x86, ia64: Move EFI_FB
vga_default_device() initialization to pci_vga_fixup()):
- cleanup remaining but always-true #ifndefs
- fix boot regression on dual-GPU Macs

Andreas, can you please test this series? It is a modification from
previous testing patch that should still work fine for you.
That testing patch would have been failing X startup on old BIOS systems
booted with vga=normal (or otherwise in VGA text mode).


Greg, in case you have scheduled above-mentioned commit for your next
stable iteration, please hold it back in the queue until this follow-up
has landed and can be included within the same stable update as alone
that patch regresses for Macs with dual-GPU and using efifb.

[PATCH 1/2] vgaarb: Drop obsolete #ifndef __ARCH_HAS_VGA_DEFAULT_DEVICE

[Bruno Prémont]

With commit 20cde694027e boot video device detection was moved from
efifb to x86 and ia64 pci/fixup.c.

Remove the left-over #ifndef check that will allways match since
the corresponding arch-specific define is gone with above patch.

[PATCH 2/2] x86, ia64: Don't default to first video device

[Bruno Prémont]

With commit 20cde694027e boot video device detection was moved from
efifb to x86 and ia64 pci/fixup.c.

For dual-GPU Apple computers above above change represents a regression
as code in efifb did forcefully override vga_default_device while the
merge did not (changed ordering of actions).

This stops setting default_vga_device when applying
IORESOURCE_ROM_SHADOW (only doing so for the detected boot GPU) and
updates logging of boot video device selection, in vgaarb which covers
VGA text-mode booting and first half of pci_fixup_video which covers
framebuffer mode (EFI, VESA).

By setting IORESOURCE_ROM_SHADOW only on effective boot GPU we also
corrects a longstanding complaint from intel driver as reported by
Andreas:
  > Does setting the ROM_SHADOW flag on (possibly) the wrong device
  > have any effect?
  Yes it does. Removing the line changes a long standing
    i915 0000:00:02.0: Invalid ROM contents
  into a
    i915 0000:00:02.0: BAR 6: can't assign [??? 0x00000000 flags
    0x20000000] (bogus alignment).
  The first is logged at KERN_ERR while the second is at KERN_INFO.

Fails again (with and without efifb).

The vga_set_default_device in vga_arbiter_add_pci_device is at fault.
It sets the boot video device to intel. Removing it makes the system
bootable again.

Could you provide your whole kernel log? I would like to understand
how your vga devices are setup and why it starts the wrong way.

If you can grab kernel log from both working and failing setups it
would be even better. The failing one is interesting for where exactly it
starts failing at boot.

While collecting debug logs, please apply following patch to get
PCI command and bridge control registers as configured when vgaarb looks
at them.

Re: [PATCH 0/2] x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()

[Andreas Noever]

[-- Attachment #1: Type: text/plain, Size: 4166 bytes --]

dmesg with your patches and vga_set_default_device commented out
(after "vgaarb: Boot video device...") as otherwise the system won't
boot.

dmesg | grep vgaarb
[    1.340118] vgaarb: PCI:0000:00:02.0 PCI_COMMAND=0007
[    1.340119] vgaarb: Boot video device: PCI:0000:00:02.0
[    1.340120] vgaarb: device added:
PCI:0000:00:02.0,decodes=io+mem,owns=io+mem,locks=none
[    1.340130] vgaarb: PCI:0000:01:00.0 PCI_COMMAND=0006
[    1.340132] vgaarb: PCI:0000:01:00.0, bridge PCI:0000:00:01.0
PCI_BRIDGE_CONTROL=0000
[    1.340133] vgaarb: device added:
PCI:0000:01:00.0,decodes=io+mem,owns=none,locks=none
[    1.340135] vgaarb: loaded
[    1.340136] vgaarb: bridge control possible 0000:01:00.0
[    1.340136] vgaarb: no bridge control possible 0000:00:02.0
[    3.798430] vgaarb: device changed decodes:
PCI:0000:00:02.0,olddecodes=io+mem,decodes=none:owns=io+mem


If the line is not commented out then vgaarb simply declares the first
(enabled) device to be the default one, which is incorrect. And the
overwrite logic in pci_fixup_video is not triggered, since a default
device has already been set.

Do you know more precisely where your system hangs when it does not boot?
That's the part I can't find in this thread.
Is it dead-locking/freezing or just booting without displaying anything
(though network coming up if connected, keyboard working (e.g. caps key).

Try blacklisting both i915 and nouveau modules (and each one individually)
an see how far your system gets. Also make sure your network comes up
automatically, so that even if display remains black you can check via
network if your system is alive and what it complains about.

The initial selection I am doing does match the PCI_COMMAND flags
as set for the devices (or masked by parent bridge), but probably none
of them has active legacy VGA I/O ports.
So the question would rather be how to determine which I/O port is active
for the Intel graphics and adjust vgaarb's "decodes"/owns interpretation
on that basis (there is no I/O active for the nvidia one).
I'm thinking about selecting only device that decodes the legacy VGA I/O
range and not those with any some other I/O range.

The short-term fix probably is to just unconditionally perform the
screen_info check in pci_fixup_video() while leaving vgaarb's initial
card selection alone for legacy hardware. Thus replicating efifb's
original behavior (and also get back incorrect ROM_SHADOW flagging).
Corresponding patch below (on top of both patches in this series, but
should apply without them as well). As mentioned in the patch this
papers over the real issue.


A second step would then be to tune vgaarb's initial selection.
Bjorn, is it possible to verify which I/O ports are decoded by a PCI
device at the time of adding it to vgaarb? If so, how? I would like to
check for legacy VGA I/O range (0x03B0-0x03DF) and only let vgaarb set
a device as default if that I/O range is decoded by the device.

Subject: [PATCH] x86: Force selection of vga_default_device on screen_info

Apple dual-GPU systems get the wrong GPU choosen by vgaarb because the
built-in Intel GPU has I/O ports active and no bridge in front that
would block legacy VGA I/O ports. (though no legacy VGA is setup)

The wrong initial selection prevents system from booting properly.

The proper solution would be to improve vgaarb's initial device
selection. Until that has been done return to behavior that efifb
implemented before the move to pci_fixup_video.

The draw-back of this old operation mode is that a wrong device
gets the IORESOURCE_ROM_SHADOW flag set.

The initial selection I am doing does match the PCI_COMMAND flags
as set for the devices (or masked by parent bridge), but probably none
of them has active legacy VGA I/O ports.
So the question would rather be how to determine which I/O port is active
for the Intel graphics and adjust vgaarb's "decodes"/owns interpretation
on that basis (there is no I/O active for the nvidia one).
I'm thinking about selecting only device that decodes the legacy VGA I/O
range and not those with any some other I/O range.

The short-term fix probably is to just unconditionally perform the
screen_info check in pci_fixup_video() while leaving vgaarb's initial
card selection alone for legacy hardware. Thus replicating efifb's
original behavior (and also get back incorrect ROM_SHADOW flagging).
Corresponding patch below (on top of both patches in this series, but
should apply without them as well). As mentioned in the patch this
papers over the real issue.


A second step would then be to tune vgaarb's initial selection.
Bjorn, is it possible to verify which I/O ports are decoded by a PCI
device at the time of adding it to vgaarb? If so, how? I would like to
check for legacy VGA I/O range (0x03B0-0x03DF) and only let vgaarb set
a device as default if that I/O range is decoded by the device.

Subject: [PATCH] x86: Force selection of vga_default_device on screen_info

Apple dual-GPU systems get the wrong GPU choosen by vgaarb because the
built-in Intel GPU has I/O ports active and no bridge in front that
would block legacy VGA I/O ports. (though no legacy VGA is setup)

The wrong initial selection prevents system from booting properly.

The proper solution would be to improve vgaarb's initial device
selection. Until that has been done return to behavior that efifb
implemented before the move to pci_fixup_video.

The draw-back of this old operation mode is that a wrong device
gets the IORESOURCE_ROM_SHADOW flag set.

I don't know of a way.  I'm pretty sure VGA devices are allowed to
respond to those legacy addresses even if there's no BAR for them, but
I haven't found a spec reference for this.  There is the VGA Enable
bit in bridges, of course (PCI Bridge spec, sec 12.1.1.  If the VGA
device is behind a bridge that doesn't have the VGA Enable bit set, it
probably isn't the default device.

Those VGA devices behind bridges are the easy ones that vgaarb selects
properly.
It's the ones not behind a bridge (integrated graphics) like the intel
one that cause problems.

For Andreas's system the discrete nvidia GPU has no I/O enabled
according to PCI_COMMAND flags while the integrated intel one does have
them (that's why the Intel GPU is chosen).

Unfortunately I don't know what makes his system choke at boot time as
he did not provide logs for the failing case.


If there is no better way to detect the proper legacy VGA device the
only remaining option would be to perform the screen_info testing in 
vga_arb_device_init() enclosed in arch #ifdef...

Attached dmesg for the failing case (obtained via ssh).

Without blacklisting a small horizontal bar of vertical green bars
appears (no x, no console).
If nouveau is blacklisted then I get a console, but X will not start
(No devices found).
If i915 is blacklisted then I do not get a console. The screen just
freezes after a few boot messages.

What is vga_default_device() used for? Is it supposed to hold the
device that is controlling the (boot) screen? Why can't we just read
the configuration from vga_switcheroo/gmux?

It's good to know that it's just the graphics (console / X) that are not
displaying properly.

The console you get is EFIFB (on the nvidia GPU to which display is routed).

Here the reason why X does not start is probably that i915 did not find
its VBIOS tables nor any connected monitor and thus X thinks "no active
output => I don't start".
Though your X would be able to start if it did not find xf86-video-intel
(intel_drv.so) and/or did find/had an explicit reference to xf86-video-fbdev
(fbdev_drv.so).

If under OSX you told your system to start on intel GPU (I think there
is an option in this direction) you system would probably boot fine as the
initial choice by vgaarb would match gmux/switcheroo settings.

This is more interesting.

Initially you had efifb printing kernel logs until nouveau gets loaded
by udev and replaces efifb. From there on possibly applegmux does not
take over correctly (it may need both i915 and nouveau active to properly
route framebuffer to panel or connector).

Though your X should be telling the same thing as for nouveau blacklisted
as nvidia GPU is not the one having boot_vga set...

If not it may be worth finding out in what state your system exactly is
with regards to graphics.

For systems not using vga_switcheroo:
  vga_default_device represents the PCI GPU that was used to boot (and
  normally handles legacy VGA I/O).
  It's never changed after boot (except eventually when a GPU gets
  hotplugged)

For systems with vga_switcheroo
  vga_default_device represents the active GPU (the one that would be
  handling legacy VGA I/O if used - and the one controlling the output
  connectors)
  vga_switcheroo is actively changing vga_default_device.


gmux is a driver for vga_switcheroo to perform the low-level platform
operations allowing switching (outputs) from one GPU to the other.


So a guess on my side would be that with both i915 and nouveau loaded
you may be able to get your display working if you can tell X to
switch GPU twice (and thus end up with matching vga_default_device
and device selected by gmux) - though I don't know how one asks for this
switch to happen.

I will propose a patch in this direction later this weekend.

[PATCH 1/2 v2] vgaarb: Don't default exclusively to first video device with mem+io

[Bruno Prémont]

With commit 20cde694027e boot video device detection was moved from
efifb to x86 and ia64 pci/fixup.c.

For dual-GPU Apple computers above change represents a regression as
code in efifb did forcefully override vga_default_device while the
merge did not (vgaarb happens prior to PCI fixup).

To improve on initial device selection by vgaarb (it cannot know if
PCI device not behind bridges see/decode legacy VGA I/O or not), move
the screen_info based check from pci_video_fixup to vgaarb's init
function and use it to refine/override decision taken while adding
the individual PCI VGA devices.
This way PCI fixup has no reason to adjust vga_default_device
anymore but can depend on its value for flagging shadowed VBIOS.

This has the nice benefit of removing duplicated code but does
introduce a #if defined() block in vgaarb.
Not all architectures have screen_info and would cause compile to
fail without it.

Andreas, does this work properly for you, including the improvement
on i915 complaint about VBIOS going from KERN_ERR to KERN_INFO?


Other arches using PCI and vgaarb that have screen_info may want
to be added to the #if defined() block or even introduce a new
CONFIG_HAVE_SCREEN_INFO or similar...

Remove the left-over #ifndef check that will allways match since
the corresponding arch-specific define is gone with above patch.

No fundamental change from previous iteration, just reversed the

Very often when something goes wrong with a kms driver we hang while doing
the initial modeset. Which is all done while holding the console_lock
(because fbdev+vt locking is just insane). You can try to get a closer
look with I915_FBDEV=n which will avoid the console_lock, but which also
won't register the legacy/compat i915 fbdev emulation any more, so greatly
changes boot behaviour.

If that doesn't lead to clues the next approach is to "carefully"
drop&reacquire console_lock at a few "interesting" places to get a few
printks out over netconsole or similar. Or just hack up entire netconsole
loggin infrastructure which bypasses printk and so all the console_lock
insanity.

It's not pretty, I know :(

In this case it's not that bad as Andreas could send the logs for all
cases (captured via ssh).

So probably console lock is not held (unless he did have to do
terminal-free ssh which I doubt).
It looks much more as if it's just the output routing that gets weird
on his Mac (or possibly any other dual-GPU MacBook where discrete GPU is
primary). Black screen but alive system :)

See follow-up posts in this thread.

If you have some uncommon or otherwise weird (EFI) multi-GPU systems
around and want to give my patches sent yesterday evening a try, you're
welcome! Some with non-Apple GPU multiplexer would be nice to have
tested as well.


The following part mentioned earlier by Andreas might be of interest to
you though (and my latest patch series should bring the improvement):

Bjorn, can you queue these two patches, probably going through -next
for a week and passing them to Linus for -rc4, adding Andreas's Tested-by
to Patch 1/2 v2?

Bjorn,

What is missing to get these two patches pushed to Linus?

Sorry, I've been working on some other regressions and overlooked this
one.  If you open a bugzilla report and mark it as a regression, that
will help keep this on my radar.

Yep, it's in linux-next and I'll send Linus a pull request for the tag [1]
tomorrow.  I meant to send it tonight, but I had to fix my for-linus branch
to remove a duplicate commit and I don't want to send the pull request
immediately afterwards.
