2011-07-25drm/radeon: Writeback endian fixesBenjamin Herrenschmidt1-7/+0
The writeback ring pointer and IH ring pointer are read using le32_to_cpu so we do not want the chip to byteswap them on big-endian. We still want to byteswap the ring itself and the IBs, so we don't touch that but we remove setting of the byteswap bits in CP_RB_RPTR_ADDR and IH_CNTL. In general, for things like that where we control all the accessors easily, we are better off doing the swap in SW rather than HW. Paradoxally, it does keep the code closer to x86 and avoid using poorly tested HW features. I also changed the use of RADEON_ to R600_ in a couple of cases to be more consistent with the surrounding code.

2011-06-20drm/radeon: avoid warnings from r600/eg irq handlers on powered off card.Dave Airlie1-8/+7
Since we were calling the wptr function before checking if the IH was even enabled, or the GPU wasn't shutdown, we'd get spam in the logs when the GPU readback 0xffffffff. This reorders things so we return early in the no IH and GPU shutdown cases.

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>

2011-01-06drm/radeon: use system_wq instead of dev_priv->wqTejun Heo1-1/+1
With cmwq, there's no reason for radeon to use a dedicated workqueue. Drop dev_priv->wq and use system_wq instead. Because radeon_driver_irq_uninstall_kms() may be called from unsleepable context, the work items can't be flushed from there. Instead, init and flush from radeon_irq_kms_init/fini(). While at it, simplify canceling/flushing of rdev->pm.dynpm_idle_work. Always initialize and sync cancel instead of being unnecessarily smart about it.
