2009-09-21drm/radeon/kms: more fixes to rv770 suspend/resume path.Dave Airlie1-10/+11
This resumes my RV730PRO (4650) RV770 (4850) fine. Still researching the RV4550 (RV710), resumes without X fine. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-18drm/radeon/kms: more alignment for rv770.c with r600.cDave Airlie1-0/+5
Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-18drm/radeon/kms: rv770 blit init called too late.Dave Airlie1-5/+14
re-align with r600 code, to init blit earlier. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-18drm/radeon/kms: move around new init path code to avoid posting at initDave Airlie1-2/+36
We really don't want to post the card at init, it takes a relatively long time and isn't required, so split the resume path into a startup path called by both init/resume and separate resume entry point to do posting. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-18drm/radeon/kms: disable VGA rendering engine before taking over VRAMDave Airlie1-0/+4
Before we use any of VRAM, we need to disable the VGA rendering engine, this render text mode into a graphical framebuffer for scanout, however it does this on vblank, and can end up overwriting the GART table and r600 shader objects. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-18drm/radeon/kms: Move radeon_get_clock_info() call out of radeon_clocks_init().Michel Dänzer1-0/+1
Someone on IRC reported problems after commit 95a8f1bf4f48b434c9f839ab5a0773f66b39d7c6 ('drm/radeon/kms: Move radeon_clocks_init() call back after getting VRAM info.'). And indeed, at least some ASIC vram_info hooks use the clock info obtained by radeon_get_clock_info(). So, move that call out of radeon_clocks_init(), ahead of the radeon_vram_info() call.

These were missed when it got split out. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-18drm/radeon/kms: don't fail if we fail to init GPU accelerationJerome Glisse1-15/+18
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. This should allow to give a working KMS setup in all case (even with non functionning accel). Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-15drm/radeon/kms: clear confusion in GART init/deinit pathJerome Glisse1-15/+22
GART static one time initialization was mixed up with GART enabling/disabling which could happen several time for instance during suspend/resume cycles. This patch splits all GART handling into 4 differents function. gart_init is for one time initialization, gart_deinit is called upon module unload to free resources allocated by gart_init, gart_enable enable the GART and is intented to be call after first initialization and at each resume cycle or reset cycle. Finaly gart_disable stop the GART and is intended to be call at suspend time or when unloading the module.

2009-09-14drm/radeon/kms: cleanup - remove radeon_share.hJerome Glisse1-1/+0
radeon_share.h was begining to give problem with include order in respect of radeon.h. It's easier and also i think cleaner to move what was in radeon_share.h into radeon.h. At the same time use the extern keyword for function shared accross the module. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-08drm/radeon/kms: add r600 KMS supportJerome Glisse1-56/+931
This adds the r600 KMS + CS support to the Linux kernel. The r600 TTM support is quite basic and still needs more work esp around using interrupts, but the polled fencing should work okay for now. Also currently TTM is using memcpy to do VRAM moves, the code is here to use a 3D blit to do this, but isn't fully debugged yet.

2009-07-29drm/radeon/kms: vram sizing on certain r100 chips needs workaround.Dave Airlie1-1/+1
If an rn50/r100/m6/m7 GPU has < 64MB RAM, i.e. 8/16/32, the aperture used to calculate the MC_FB_LOCATION needs to be worked out from the CONFIG_APER_SIZE register, and not the actual vram size. TTM VRAM size was also being initialised wrong, use actual vram size to initialise it. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-06-15drm/radeon: introduce kernel modesetting for radeon hardwareJerome Glisse1-0/+124
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).
