* drm: block userspace under allocating buffer and having drivers overwrite it ↵Dave Airlie2010-08-171-2/+2
| | | | | | | | | | | | | | | | (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/radeon: add basic zmask/hiz support (v4)Dave Airlie2010-08-021-0/+1
| | | | | | | | | | | | | | | This interface allows userspace to request hyperz support, it probably needs more locking, and really reporting that you can have hyperz is racy since someone else might get it before you do. v2: modify so we pass 0 valued packets to let DDX/r300c keep working. also fixed incorrect 0x4f1c reference. v3: fixup zb_bw_cntl so older drivers keep working v4: add locking, fixup SC_HYPERZ_EN - patch stream to disable hiz Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/radeon/kms/r6xx+: add query for tile config (v2)Alex Deucher2010-08-021-0/+1

* drm/radeon/kms/evergreen: set accel_enabledAlex Deucher2010-06-081-0/+1
| | | | | | | | | | | | | | This is needed to enable accel in the ddx. However, due to a bug in older versions of the ddx, it relies on accel being disabled in order to load properly on evergreen chips. To maintain compatility, we add a new get accel param and call that from the ddx. The old one always returns false for evergreen cards. [this fixes a regression with older userspaces on newer kernels]. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | Userspace can query if acceleration is working or not true get info ioctl and could fallback to software if for some reason kernel failed to initialize KMS.

* drm/radeon/kms: add initial colortiling support.Dave Airlie2009-07-291-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds new set/get tiling interfaces where the pitch and macro/micro tiling enables can be set. Along with a flag to decide if this object should have a surface when mapped. The only thing we need to allocate with a mapped surface should be the frontbuffer. Note rotate scanout shouldn't require one, and back/depth shouldn't either, though mesa needs some fixes. It fixes the TTM interfaces along Thomas's suggestions, and I've tested the surface stealing code with two X servers and not seen any lockdep issues. I've stopped tiling the fbcon frontbuffer, as I don't see there being any advantage other than testing, I've left the testing commands in there, just flip the fb_tiled to true in radeon_fb.c Open: Can we integrate endian swapping in with this? Future features: texture tiling - need to relocate texture registers TXOFFSET* with tiling info. This also merges Michel's cleanup surfaces regs at init time patch even though it makes sense on its own, this patch really relies on it. Some PowerMac firmwares set up a tiling surface at the beginning of VRAM which messes us up otherwise. that patch is: Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/radeon: introduce kernel modesetting for radeon hardwareJerome Glisse2009-06-151-0/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add kernel modesetting support to radeon driver, use the ttm memory manager to manage memory and DRM/GEM to provide userspace API. In order to avoid backward compatibility issue and to allow clean design and code the radeon kernel modesetting use different code path than old radeon/drm driver. When kernel modesetting is enabled the IOCTL of radeon/drm driver are considered as invalid and an error message is printed in the log and they return failure. KMS enabled userspace will use new API to talk with the radeon/drm driver. The new API provide functions to create/destroy/share/mmap buffer object which are then managed by the kernel memory manager (here TTM). In order to submit command to the GPU the userspace provide a buffer holding the command stream, along this buffer userspace have to provide a list of buffer object used by the command stream. The kernel radeon driver will then place buffer in GPU accessible memory and will update command stream to reflect the position of the different buffers. The kernel will also perform security check on command stream provided by the user, we want to catch and forbid any illegal use of the GPU such as DMA into random system memory or into memory not owned by the process supplying the command stream. This part of the code is still incomplete and this why we propose that patch as a staging driver addition, future security might forbid current experimental userspace to run. This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX (radeon up to X1950). Works is underway to provide support for R6XX, R7XX and newer hardware (radeon from HD2XXX to HD4XXX).

* drm: reorganise drm tree to be more future proof.Dave Airlie2008-07-141-0/+749
With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
