2005-11-30[PATCH] SiS DRM: Fix possible NULL dereferenceEgbert Eich
This fixes a NULL pointer reference in DRM. The SiS driver tries to allocate a big chunk of memory, but the return value is never checked. Reported in Novell bugzilla #132271: https://bugzilla.novell.com/show_bug.cgi?id=132271 Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-11-24drm: fix quiescent lockingDave Airlie
A fix for a locking bug which is triggered when a client tries to lock with flag DMA_QUIESCENT (typically the X server), but gets interrupted by a signal. The locking IOCTL should then return an error, but if DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it has the lock. In addition The client waits for DMA_QUISCENT and possibly DMA_READY without having the lock. From: Thomas Hellstrom Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-11-23drm: move is_pci to the end of the structureDave Airlie
We memset the structure across opens except for the flags. The correct fix is more intrusive but this should fix a problem with bad iounmaps seen on AGP radeons acting like PCI ones. Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-11-23drm: add __GFP_COMP to the drm_alloc_pagesDave Airlie
The DRM only uses drm_alloc_pages for non-SG PCI cards using DRM. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-11-23I think that if a PCI bus is a root bus, attached to a host bridge not aDave Airlie
PCI->PCI bridge, then bus->self is allowed to be NULL. Certainly that's the case on my Pegasos, and it makes the MGA DRM driver oops... Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-11-09[PATCH] drm fixup pci gart settingsDave Airlie
Fix the PCIGART increment and add a cpu_to_le32 for ppc (untested) Paulus was unsure if we need to cpu_to_le32 but the old code was definitely wrong, so make it consistent and let the PPC guys figure it out later.

Manual fixups for some clashes due to re-indenting.
2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-10-26[PATCH] fix radeon_cp_init_ring_buffer()Ivan Kokshaysky
I've seen similar failure on alpha. Obviously, someone forgot to convert sg->handle stuff for PCI gart case. Signed-off-by: Dave Airlie <airlied@linux.ie> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-19[PATCH] fix MGA DRM regression before 2.6.14Dave Airlie
I've gotten a report on lkml, of a possible regression in the MGA DRM in 2.6.14-rc4 (since -rc1), I haven't been able to reproduce it here, but I've figured out some possible issues in the mga code that were definitely wrong, some of these are from DRM CVS, the main fix is the agp enable bit on the old code path still used by everyone.....

2005-09-05drm: fix issue with handle lookup for a 0 handleDave Airlie

2005-08-23drm: fix a bad VERSION check.Dave Airlie
I found why my G5 was crashing when using the linux-2.6 version of the DRM + git-drm.patch from 2.6.13-rc6-mm1, but not with the CVS DRM. The reason was that dev->agp->cant_use_aperture wasn't getting set, and the reason for that was that <linux/version.h> no longer gets included and the #if LINUX_VERSION_CODE < 0x020408 in drm_agpsupport.c was going the wrong way. With this patch (and a few others) a 32-bit server works correctly, as does DRI. From: Paul Mackerras <paulus@samba.org> Signed-off-by: Dave Airlie <airlied@linux.ie>

2005-08-05drm: switch drm_handle_t to unsigned intDave Airlie
This converts the drm_handle_t to unsigned int. This is currently safe to do as we don't pass these across the kernel/user boundary, but userspace does use these, but no-one builds userspace against the kernel headers at present so it is okay to switch over the kernel copy of drm.h at this point. (The CVS tree will switch over soon in sync with some Mesa changes) From: Egbert Eich <eich@suse.de> Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-08-05drm: updated DRM map patch for 32/64 bit systemsDave Airlie
I basically combined Paul's patches with additions that I had made for PCI scatter gather. I also tried more carefully to avoid problems with the same token assigned multiple times while trying to use the base address in the token if possible to gain as much backward compatibility as possible for broken DRI clients.
