2011-04-13drm/radeon/kms: clean up gart dummy page handlingAlex Deucher1-4/+0
As per Konrad's original patch, the dummy page used by the gart code and allocated in radeon_gart_init() was not freed properly in radeon_gart_fini(). At the same time r6xx and newer allocated and freed the dummy page on their own. So to do Konrad's patch one better, just remove the allocation and freeing of the dummy page in the r6xx, 7xx, evergreen, and ni code and allocate and free in the gart_init/fini() functions for all asics.

2011-03-14drm/radeon: fix problem with changing active VRAM size. (v2)Dave Airlie1-2/+1
So we used to use lpfn directly to restrict VRAM when we couldn't access the unmappable area, however this was removed in 93225b0d7bc030f4a93165347a65893685822d70 as it also restricted the gtt placements. However it was only later noticed that this broke on some hw. This removes the active_vram_size, and just explicitly sets it when it changes, TTM/drm_mm will always use the real_vram_size, and the active vram size will change the TTM size used for lpfn setting. We should re-work the fpfn/lpfn to per-placement at some point I suspect, but that is too late for this kernel. Hopefully this addresses: https://bugs.freedesktop.org/show_bug.cgi?id=35254 v2: fix reported useful VRAM size to userspace to be correct. Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-10-12drm/radeon/kms: avoid corner case issue with unmappable vram V2Jerome Glisse1-0/+2
We should not allocate any object into unmappable vram if we have no means to access them which on all GPU means having the CP running and on newer GPU having the blit utility working. This patch limit the vram allocation to visible vram until we have acceleration up and running. Note that it's more than unlikely that we run into any issue related to that as when acceleration is not woring userspace should allocate any object in vram beside front buffer which should fit in visible vram.

2010-10-06drm/radeon/kms: enable writeback (v2)Alex Deucher1-5/+10
When writeback is enabled, the GPU shadows writes to certain registers into a buffer in memory. The driver can then read the values from the shadow rather than reading back from the register across the bus. Writeback can be disabled by setting the no_wb module param to 1. On r6xx/r7xx/evergreen, the following registers are shadowed: - CP scratch registers - CP read pointer - IH write pointer On r1xx-rr5xx, the following registers are shadowed: - CP scratch registers - CP read pointer v2: - Combine wb patches for r6xx-evergreen and r1xx-r5xx - Writeback is disabled on AGP boards since it tends to be unreliable on AGP using the gart. - Check radeon_wb_init return values properly.

- Separate dynpm and profile based power management methods. You can select the pm method by echoing the selected method ("dynpm" or "profile") to power_method in sysfs. - Expose basic 4 profile in profile method "default" - default clocks "auto" - select between low and high based on ac/dc state "low" - DC, low power mode "high" - AC, performance mode The current base profile is "default", but it should switched to "auto" once we've tested on more systems. Switching the state is a matter of echoing the requested profile to power_profile in sysfs. The lowest power states are selected automatically when dpms turns the monitors off in all states but default. - Remove dynamic fence-based reclocking for the moment. We can revisit this later once we have basic pm in. - Move pm init/fini to modesetting path. pm is tightly coupled with display state. Make sure display side is initialized before pm. - Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume. - Remove dynpm module option.

2010-04-06drm/radeon/kms: fence cleanup + more reliable GPU lockup detection V4Jerome Glisse1-6/+0
This patch cleanup the fence code, it drops the timeout field of fence as the time to complete each IB is unpredictable and shouldn't be bound. The fence cleanup lead to GPU lockup detection improvement, this patch introduce a callback, allowing to do asic specific test for lockup detection. In this patch the CP is use as a first indicator of GPU lockup. If CP doesn't make progress during 1second we assume we are facing a GPU lockup. To avoid overhead of testing GPU lockup frequently due to fence taking time to be signaled we query the lockup callback every 500msec. There is plenty code comment explaining the design & choise inside the code. This have been tested mostly on R3XX/R5XX hw, in normal running destkop (compiz firefox, quake3 running) the lockup callback wasn't call once (1 hour session). Also tested with forcing GPU lockup and lockup was reported after the 1s CP activity timeout. V2 switch to 500ms timeout so GPU lockup get call at least 2 times in less than 2sec. V3 store last jiffies in fence struct so on ERESTART, EBUSY we keep track of how long we already wait for a given fence V4 make sure we got up to date cp read pointer so we don't have false positive Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
