drm: drop setting vm_file to filp

2012-03-05T11:19:08Z

Talking to Al Viro on irc, we can see no possible reason for doing this, the upper mmap code does it. The code has been there since first import into drm tree I can find. Al tracked down this as a requirement pre 2.3.51 hasn't been needed since. Acked-by: Al Viro Signed-off-by: Dave Airlie

drm: move pci bus master enable into driver.

2012-02-16T18:31:07Z

The current enabling of bus mastering in the drm midlayer allows a large race condition under kexec. When a kexec'ed kernel re-enables bus mastering for the GPU, previously setup dma blocks may cause writes to random pieces of memory. On radeon the writeback mechanism can cause these sorts of issues. This patch doesn't fix the problem, but it moves the bus master enable under the individual drivers control so they can move enabling it until later in their load cycle and close the race. Fix for radeon kms driver will be in a follow-up patch. Signed-off-by: Dave Airlie

Revert "drm/i810: cleanup reclaim_buffers"

2012-01-30T09:31:25Z

This reverts commit 87499ffdcb1c70f66988cd8febc4ead0ba2f9118. Where is that paper bag ... ah here. I've failed to take an odd interaction between my other cleanups and this reclaim_buffers patch into account and also failed to properly test it. Looks like there are more dragons and hidden trapdoors in the drm release path than actual lines of code. Until I get a clue, let's just revert this.

drm/i810: don't acces hw regs in lastclose

2011-12-22T18:54:58Z

i810 uses a userspace provided mmio map using the drm core map infrastructure. By the time we reach lastclose, this is all gone and our mmio_map pointer points at freed memory. Depending upon luck that still works, most often it just oopses. Aside: drm maps aren't refcounted, so userspace can essentially oops the kernel any time it wants to. Who cares.

drm/i810: cleanup reclaim_buffers

2011-12-22T18:54:43Z

My dear old i815 always hits the deadlocked on reclaim_buffers warning. Switch over to the idlelock duct-tape on hope that works better. I've fired up my i815 and now closing glxgears doesn't take 5 seconds anymore. \o/ Signed-off-by: Daniel Vetter

drm: Make the per-driver file_operations struct const

2011-11-11T11:14:47Z

From fdf1fdebaa00f81de18c227f32f8074c8b352d50 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Sun, 30 Oct 2011 19:06:07 -0700 Subject: [PATCH] drm: Make the per-driver file_operations struct const The DRM layer keeps a copy of struct file_operations inside its big driver struct... which prevents it from being consistent and static. For consistency (and the general security objective of having such things static), it's desirable to get this fixed. This patch splits out the file_operations field to its own struct, which is then "static const", and just stick a pointer to this into the driver struct, making it more consistent with how the rest of the kernel does this.

gpu: add module.h to drivers/gpu files as required.

2011-10-31T23:32:03Z

So that we don't get build failures once the implicit module.h presence is removed. Signed-off-by: Paul Gortmaker

drm: rework PCI/platform driver interface.

2011-02-07T03:09:36Z

This abstracts the pci/platform interface out a step further, we can go further but this is far enough for now to allow USB to be plugged in. The drivers now just call the init code directly for their device type. Signed-off-by: Dave Airlie

drm/i810: remove the BKL

2011-02-07T02:15:04Z

SMP i810 systems were practically nonexistent and the configuration was not officially supported by Intel at the time when Pentium-III was common. With this change, it is still possible to build a distribution kernel that has support for SMP and includes the i810 driver without the BKL. As a precaution, check for the theoretical SMP case at run time and refuse to load the driver. We also need to disable CONFIG_PREEMPT builds for this driver.
