| * drm/gem: handlecount isn't really a kref so don't make it one.Dave Airlie2010-10-011-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were lots of places being inconsistent since handle count looked like a kref but it really wasn't. Fix this my just making handle count an atomic on the object, and have it increase the normal object kref. Now i915/radeon/nouveau drivers can drop the normal reference on userspace object creation, and have the handle hold it. This patch fixes a memory leak or corruption on unload, because the driver had no way of knowing if a handle had been actually added for this object, and the fbcon object needed to know this to clean itself up properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The information supplied by userspace through these ioctls is only accessible by dev->drw_idr. But there's no in-tree user of that. Also userspace does not really care about return values of these ioctls, either. Only hw/xfree86/dri/dri.c from the xserver actually checks the return from adddraw and keeps on trying to create a kernel drawable every time somebody creates a dri drawable. But since that's now a noop, who cares. Therefore it's safe to replace these three ioctls with noops and rip out the implementation.

* drm: block userspace under allocating buffer and having drivers overwrite it ↵Dave Airlie2010-08-171-2/+4
| | | | | | | | | | | | | | | | (v2) With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory. This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation. Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau. v2: fix nouveau pushbuf arg (thanks to Ben for pointing it out) Reported-by: Linus Torvalds <torvalds@linuxfoundation.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: Fix support for PCI domainsBenjamin Herrenschmidt2010-08-101-6/+16
| | | | | | | | | | | | | | | | | (For some reason I thought that went in ages ago ...) This fixes support for PCI domains in what should hopefully be a backward compatible way along with a change to libdrm. When the interface version is set to 1.4, we assume userspace understands domains and the world is at peace. We thus pass proper domain numbers instead of 0 to userspace. The newer libdrm will then try 1.4 first, and fallback to 1.1, along with ignoring domains in the later case (well, except on alpha of course) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: kill BKL from common codeArnd Bergmann2010-08-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This restricts the use of the big kernel lock to the i830 and i810 device drivers. The three remaining users in common code (open, ioctl and release) get converted to a new mutex, the drm_global_mutex, making the locking stricter than the big kernel lock. This may have a performance impact, but only in those cases that currently don't use DRM_UNLOCKED flag in the ioctl list and would benefit from that anyway. The reason why i810 and i830 cannot use drm_global_mutex in their mmap functions is a lock-order inversion problem between the current use of the BKL and mmap_sem in these drivers. Since the BKL has release-on-sleep semantics, it's harmless but it would cause trouble if we replace the BKL with a mutex. Instead, these drivers get their own ioctl wrappers that take the BKL around every ioctl call and then set their own handlers as DRM_UNLOCKED.

Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* drm: convert drm_ioctl to unlocked_ioctlArnd Bergmann2009-12-181-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | drm_ioctl is called with the Big Kernel Lock held, which shows up very high in statistics on vfs_ioctl. Moving the lock into the drm_ioctl function itself makes sure we blame the right subsystem and it gets us one step closer to eliminating the locked version of fops->ioctl. Since drm_ioctl does not require the lock itself, we only need to hold it while calling the specific handler. The 32 bit conversion handlers do not interact with any other code, so they don't need the BKL here either and can just call drm_ioctl. As a bonus, this cleans up all the other users of drm_ioctl which now no longer have to find the inode or call lock_kernel. [airlied: squashed the non-driver bits of the second patch in here, this provides the flag for drivers to use to select unlocked ioctls - but doesn't modify any drivers].

|/ | | | | | | | | | | | | VGA arb requires DRM support for non-kms drivers, to turn on/off irqs when disabling the mem/io regions. VGA arb requires KMS support for GPUs where we can turn off VGA decoding. Currently we know how to do this for intel and radeon kms drivers, which allows them to be removed from the arbiter. This patch comes from Fedora rawhide kernel. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: GEM handles are u32, not intPekka Paalanen2009-08-271-2/+2
| | | | | | | | | | Several functions in the GEM kernel API used int as handle type, but user API has it __u32 which is also the intended type. Replace int with u32. Signed-off-by: Pekka Paalanen <pq@iki.fi> Signed-off-by: Dave Airlie <airlied@redhat.com>
* DRM: Add the explanation about DRM debug levelZhao Yakui2009-08-041-0/+31
| | | | | | | | Add the explanation about DRM debug level in the drmP header file. This is to explain how/where to use the different DRM debug level. Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: Remove the macro defintion of DRM_DEBUG_MODEZhao Yakui2009-08-041-7/+0
| | | | | | | | | | | Two macro definitions of DRM_DEBUG_KMS/MODE can be used to add the debug info related with KMS. It is confusing. So remove the macro definition of DRM_DEBUG_MODE. Instead it can be replaced by the DRM_DEBUG_KMS. Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Acked-by: Ian Romanick <ian.d.romanick@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: Remove the unused prefix in DRM_DEBUG_KMS/DRIVER/MODEZhao Yakui2009-08-041-9/+9
| | | | | | | | | | | We will have to add a prefix when using the macro defintion of DRM_DEBUG_KMS /DRM_DEBUG_DRIVER/MODE. It is not convenient. We should use the DRM_NAME as default prefix. So remove the prefix in the macro definition of DRM_DEBUG_KMS/DRIVER/MODE.
