Subject: [PATCH 4.14 104/167] Revert "apple-gmux: lock iGP IO to protect from vgaarb changes"
Date: Wed, 21 Feb 2018 13:48:35 +0100	[thread overview]
Message-ID: <20180221124530.053661678@linuxfoundation.org> (raw)
In-Reply-To: <20180221124524.639039577@linuxfoundation.org>

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lukas Wunner <lukas@wunner.de>

commit d6fa7588fd7a8def4c747c0c574ce85d453e3788 upstream.

Commit 4eebd5a4e726 ("apple-gmux: lock iGP IO to protect from vgaarb
changes") amended this driver's ->probe hook to lock decoding of normal
(non-legacy) I/O space accesses to the integrated GPU on dual-GPU
MacBook Pros.  The lock stays in place until the driver is unbound.

The change was made to work around an issue with the out-of-tree nvidia
graphics driver (available at http://www.nvidia.com/object/unix.html).
It contains the following sequence in nvidia/nv.c:

	#if defined(CONFIG_VGA_ARB) && !defined(NVCPU_PPC64LE)
	#if defined(VGA_DEFAULT_DEVICE)
	    vga_tryget(VGA_DEFAULT_DEVICE, VGA_RSRC_LEGACY_MASK);
	#endif
	    vga_set_legacy_decoding(dev, VGA_RSRC_NONE);
	#endif

This code was reported to cause deadlocks with VFIO already in 2013:
https://devtalk.nvidia.com/default/topic/545560

I've reported the issue to Nvidia developers once more in 2017:
https://www.spinics.net/lists/dri-devel/msg138754.html

On the MacBookPro10,1, this code apparently breaks backlight control
(which is handled by apple-gmux via an I/O region starting at 0x700),
as reported by Petri Hodju:
https://bugzilla.kernel.org/show_bug.cgi?id=86121

I tried to replicate Petri's observations on my MacBook9,1, which uses
the same Intel Ivy Bridge + Nvidia GeForce GT 650M architecture, to no
avail.  On my machine apple-gmux' I/O region remains accessible even
with the nvidia driver loaded and commit 4eebd5a4e726 reverted.
Petri reported that apple-gmux becomes accessible again after a
suspend/resume cycle because the BIOS changed the VGA routing on the
root port to the Nvidia GPU.  Perhaps this is a BIOS issue after all
that can be fixed with an update?

In any case, the change made by commit 4eebd5a4e726 has turned out to
cause two new issues:

* Wilfried Klaebe reports a deadlock when launching Xorg because it
  opens /dev/vga_arbiter and calls vga_get(), but apple-gmux is holding
  a lock on I/O space indefinitely.  It looks like apple-gmux' current
  behavior is an abuse of the vgaarb API as locks are not meant to be
  held for longer periods:
  https://bugzilla.kernel.org/show_bug.cgi?id=88861#c11
  https://bugzilla.kernel.org/attachment.cgi?id=217541

* On dual GPU MacBook Pros introduced since 2013, the integrated GPU is
  powergated on boot und thus becomes invisible to Linux unless a custom
  EFI protocol is used to leave it powered on.  (A patch exists but is
  not in mainline yet due to several negative side effects.)  On these
  machines, locking I/O to the integrated GPU (as done by 4eebd5a4e726)
  fails and backlight control is therefore broken:
  https://bugzilla.kernel.org/show_bug.cgi?id=105051

So let's revert commit 4eebd5a4e726 please.  Users experiencing the
issue with the proprietary nvidia driver can comment out the above-
quoted problematic code as a workaround (or try updating the BIOS).
