We need this for the framebuffer in order to ensure that the kernel
framebuffer layer can handle it when using KMS. Except for the base
framebuffer this isn't a concern.
Add an npage field to the gtt as too many copies of the page calculation
are getting spread around the code.

Restructure this to work the same way as the i915 frame buffer does. That
cleans up various chunks of code.
We can now set a mode in modetest but mode restore is a bit iffy

If we get a user frame buffer destroyed which is being displayed then clean
up the mess nicely. We can now run a slightly modified modetest including setting
modes, and handling crashes.
Modetest still blows up but this is because libdrm 2.4.25 is busted.

From: Alan Cox <alan@linux.intel.com>
We have a FIXME to do the power management for which the framework now
exists, and we also need to deal with an erratum. Some operations exactly 8
pixels wide or high fail. The work around is to do two smaller ones (see
the Intel released X driver bits) but for console quite frankly if it's
8bits wide and/or high its not worth it so fall back.

We really want to move towards a completely abstracted interface rather
than having tons of per chip junk in the same files.
Begin with the power code which is probably the worst offender. Add a set
of methods, initialise a dev_priv->ops pointer and rip the chip specifics
out of the power code. While we are it pick up the display init bits.
So we know it's now chip specifics clean remove the psb_ naming from it.

This caught my eye, and I realize that I'm in the process of

I've been eliminating drm/i915's calls to read_cache_page_gfp(),
while you've been adding them to staging/gma500. It still works in
3.0-rc, but if my further changes go through from mmotm to 3.1-rc,
then read_cache_page_gfp() on a shmem/tmpfs file will crash on the
lack of a readpage method (we could easily make it error instead
of crash, but you'd probably prefer something that actually works).
As example, below is the patch where I updated drm/i915 to be ready
for the changeover. They set __GFP_RECLAIMABLE on the mapping because
they've got a way to discard unpinned object pages when memory is tight;
and sometimes add in __GFP_NORETRY|__GFP_NOWARN when allocating.
I'm guessing you'd just want to use shmem_read_mapping_page() throughout,
after initializing mapping with the appropriate flags (GFP_HIGHUSER_MOVABLE
is fs/inode.c's default: maybe your pages aren't easily movable and you'd
better say GFP_HIGHUSER, or maybe you have reason to need GFP_KERNEL).

commit 5949eac4d9b5bf936c12cb7ec3a09084c1326834
Author: Hugh Dickins <hughd@google.com>

drm/i915: use shmem_read_mapping_page
Soon tmpfs will stop supporting ->readpage and read_cache_page_gfp(): once
"tmpfs: add shmem_read_mapping_page_gfp" has been applied, this patch can
be applied to ease the transition.
Make i915_gem_object_get_pages_gtt() use shmem_read_mapping_page_gfp() in
the one place it's needed; elsewhere use shmem_read_mapping_page(), with
the mapping's gfp_mask properly initialized.
Forget about __GFP_COLD: since tmpfs initializes its pages with memset,
asking for a cold page is counter-productive.
Include linux/shmem_fs.h also in drm_gem.c: with shmem_file_setup() now
declared there too, we shall remove the prototype from linux/mm.h later.

I need the pages in the low 4GB ideally and have no way to release them
if they are pinned. For the usage pattern I have that's not a problem.
At the moment the 4G isn't a problem either as you can't attach enough
memory to cause problems to any of these devices.
What I don't entirely understand from your change is what stops another
user task with the shmemfs file handle open from doing something else
which changes the mapping flags, or is it guaranteed that only the
mapping owner gets to play ?

Maybe you'll want to use GFP_KERNEL | GFP_DMA32.

My changes (which were directed to eliminating shmem_readpage, which
complicates shmem.c somewhat) haven't made any difference there: except
that, like you, I'm wary of letting people mess with gfp flags all over,
so preferred drm/i915 to set the right flags on the mapping initially,
then add in the __GFP_NORETRY | __GFP_NOWARN in the one place needed,
instead of using the _gfp()-modifying variant everywhere.
I don't think a user task has any interface to change the mapping flags,
does it? But Linus freaked out a little 18 months ago when he noticed
drm/i915 fiddling with mapping flags via mapping_set_gfp_mask() (whose
declaration comments "This is non-atomic. Only to be used before the
mapping is activated."), so gave them read_cache_page_gfp() instead.
I'd prefer we didn't have to support it, but i915 does have good use
for it: so long as they only play with transient flags such as NORETRY
(which will affect the allocation being made by the caller, but not
affect mapping itself or concurrent allocations to it from elsewhere).
But your question does make me worry about when a page is brought back
from swap. The swapin readahead code is liable to read in several pages
with the same gfp mask as the page it's actually needing; but if adjacent
swap locations have been used for pages of objects with different gfp
needs, that could cause a problem. (NUMA mempolicy gets ignored by
swapin in the same way.)
Your <4GB pages won't get swapped out while they're pinned. But can
it happen that they'd be unpinned, swapped out, swapped back in >4GB
pages, then cause trouble for you when needed again?
I didn't care very deeply about the difference between __GFP_MOVABLE
and __GFP_RECLAIMABLE in the i915 case, but your 4GB requirement sounds
more important to get right (though you do say "ideally" above: if it's
just a matter of slowdown, maybe we can ignore it for now).

It does look that way, in which case that will eventually need fixing. At
the moment you can't put enough memory into a device using these chips
but that won't always be true I imagine.

Thanks, I won't worry about it at this moment, but we'd better not forget.
If it's easy for you to include a WARN_ON_ONCE check (perhaps
on page_to_pfn(page)), that may be worth doing to remind us.
It's a bit sad to learn this requirement just after I'd completed
removing the readpage copying code, and a bit strange to have shmem
confined by hardware constraints; but I guess that's what we took on
when we opened it up to GEM.
It will probably make sense for me to add synchronous migration when
a shmem swap page is found not to match the contraints wanted by the
mapping it goes into: mainly for NUMA, but covering your case too.

I recall seeing the GMA driver using the TTM at some point
(but then those calls disappared), and I've written a patch to deal with
a similar issue (where the DMA and the virtual address needed to
be passed along to the code that programs the cards MMU).
It also survives suspend/resume, swap, etc.
https://lkml.org/lkml/2011/8/30/460
Don't know if it would be too complicated to make the GMA500 code
use TTM, and the URL I posted still needs a review, but perhaps
that could solve this problem in the future for you guys?

I think we need to revisit this problem. On 3.1-rc4 with some of my own changes
I've just triggered read_cache_page_gfp in psb_gtt_attach_pages when trying to
set a resolution that doesn't fit in stolen memory. Replacing it with
shmem_read_mapping_page seems to work but how do we go about solving the >4GB
issue? Is it ok for now to just use shmem_read_mapping_page or did any of you
have a better solution?
Thanks

I was surprised to see drivers/staging/gma500 appearing still to use
read_cache_page_gfp(). I assumed that since nobody was complaining,
it must be on a currently unusable path. But you have code coming up,
that now enables that path?
Am I right to think that your immediate problem is just the oops in
__read_cache_page(), that you're not yet about to hit the 4GB issue?
I haven't rushed to address the 4GB issue, but what I have in mind is
killing two-and-a-half birds with one stone, by putting a little cookie
into the swapper_space radix_tree when we free a swapcache page, that
specifies node/zone and hashes object/offset.
NUMA mempolicies are too complex to be encapsulated in a sizeof(long)
cookie, but it should improve the common case after swapin; while
solving your 4GB GEM case, and vastly speeding up swapoff.
Here's the kind of patch I imagined would be going in for gma500, that
specifies __GFP_DMA32 on the mapping, so even swapoff can know that
this object needs its pages below 4GB (even before my recent changes,
swapoff would have broken you by inserting higher pages in the cache)
- once I implement that. But I've not tested this patch at all...
[PATCH] gma500: use shmem_read_mapping_page
In 3.1 onwards, read_cache_page_gfp() just oopses on GEM objects:
switch gma500 over to shmem_read_mapping_page() like i915. But when
larger devices arrive, gma500 will need to keep its pages below 4GB, so
specify __GFP_DMA32 (though that limit is not yet enforced in shmem.c).

Yes, I have a couple of patches for getting SDVO to properly set up DDC.
It seems we hit that path when framebuffer size exceeds a certain limit.

Correct, I have only seen 1GB and 2GB platforms so far. But the driver
does support platforms that I haven't got my hands on yet.

There are some other issues with SDVO when running at higher resolutions
that triggers the path. Will test your patch as soon as I get those things
sorted out, though it looks ok to me.

Without really knowing the details about how hard it would be to
implement, it would solve one additional problem if we could have a
per-mapping callback fxn for allocating pages.
At least on ARM (but I guess probably some other architectures too),
we really want to avoid having a page mapped cachable in the kernel,
and uncached/writecombine in userspace. With a per-mapping page
allocation fxn, we could do something like
dma_alloc_coherant/writecombine (for example) to allocate backing
pages for GEM buffers which are mmap'd to userspace as something other
than cachable.

It feels to me like GEM is pulling shmem in an ever more alien direction:
these device constraints are so foreign to the nature of tmpfs; and
beyond my expertise, so that I'd be ever more likely to make the wrong
decisions (mixing swap and uncached pages? hmmm).
We ought to re-examine whether GEM should be using tmpfs at all, whether
it would be better served by its own filesystem or other infrastructure.
Really, the one reason for wanting tmpfs is to have the benefit of offload
to swap (and that is indeed a feature I wouldn't care to distribute around
to drivers).

For the most part we fixed that. You can now have a GEM object that is
backed by a private memory object rather than having to be tmpfs.
GMA500 uses it to attach 'stolen' memory to GEM handles, and at least
one other pending submission uses it with a private CMA style allocator.
The gma500 report seems an odd one - no GMA500 box has >4GB memory so how
did the test code get a page that was unsuitable - is the test buggy ?

This is the first I heard of some gma500 test seeing a problem with >4GB.
In this thread we have Patrik hitting the oops in read_cache_page_gfp()
because of some changes he is preparing, but I thought he and Rob were
just thinking ahead when they raise the 4GB issue.
Can you point us to another thread on a another list?

Well, that means we could implement our own shmem/tmpfs.. although I'm
not entirely sure that I would want to.. a couple drm drivers are
using private memory objects, but I think primarily for scanout
buffers (which can't really be swapped out anyways). I don't think
we'd want to use this for everything.
What troubles could you see for swap+uncached (or more likely,
writecombine) pages?

That should never occur. I would argue the driver is responsible for
putting the cache state of the page back sensibly before it unpins it.
That's a simple enough rule and one I think all the drivers follow at
this point.

no, what I'm trying to avoid is having two virtual mappings to the
same physical page with different cache attributes. This is not
allowed on some architectures (like ARM)

Nor x86... that's a matter for the core architecture code to deal with
not the drivers.

hmm, maybe I'm missing something, but how is this ensured on x86?
Default drm_gem_mmap() maps pages to userspace as writecombine.. but
if page comes from kernel linear map (not highmem), that will be a
cached kernel virtual mapping in addition to the wc userspace mapping.

Hi Alan
I didn't hit any >4GB issues but when I got SDVO working I tried setting
1920x1080 which needs more then the ~8MB that BIOS sets aside
as stolen memory.
What happens is that a gem object outside stolen mem is created and
when we try to pin it we go down the path:
psb_gtt_pin -> psb_gtt_attach_pages -> read_cache_page_gfp
This triggers the following oops:

We don't want to carry all the extra gunk around on every device so use the
splitting work so far to tidy this up. Poulsbo is still mandatory as it is
used in bits by the other drivers and not neatly modularised.

This is generic for the PC class devices and also very similar to the i915
intel_bios.c so rename it. That way the commonality will be obvious and we
can look at merging them one day, or at least synching them up.

fact only the non MID devices use the functions but they are small and
having the name match i915 is going to help any future merging type work.

Move this over. In actual fact there are some underlying differences as
some devices have more MMU contexts, but for our 2D purposes we don't
actually care.

From: Alan Cox <alan@linux.intel.com>

I've applied this series, but I get the following error when building:
make[2]: *** No rule to make target `drivers/staging/gma500/cdv_intel_crt.o', needed by `drivers/staging/gma500/psb_gfx.o'. Stop.
Care to send a follow-on patch fixing this?
Also, should I be able to select all of the different platforms even
though I'm only building for a x86-64 platform?
thanks,
