| * drm/nv50: fix a couple of vm init issuesFrancisco Jerez2010-12-15
| | | | | | | | | | | | | | | | | | Fixes overwriting the first page table entry when testing that the PRAMIN BAR can be correctly read/written, and adds an additional bar flush after poking the BAR3 control regs.

| * drm/nouveau: kick vram functions out into an "engine"Ben Skeggs2010-12-07
| | | | | | | | | | | | | | | | | | NVC0 will be able to share some of nv50's paths this way. This also makes it the card-specific vram code responsible for deciding if a given set of tile_flags is valid, rather than duplicating the allowed types in nv50_vram.c and nouveau_gem.c Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * drm/nv50: implement global channel address space on new VM codeBen Skeggs2010-12-07
| | | | | | | | | | | | | | As of this commit, it's guaranteed that if an object is in VRAM that its GPU virtual address will be constant. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * drm/nv50: implement custom vram mmBen Skeggs2010-12-07
| | | | | | | | | | | | | | | | | | | | | | This is required on nv50 as we need to be able to have more precise control over physical VRAM allocations to avoid buffer corruption when using buffers of mixed memory types. This removes some nasty overallocation/alignment that we were previously using to "control" this problem. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * drm/nouveau: fix use of drm_mm_node in semaphore objectBen Skeggs2010-12-07
| | | | | | | | | | | | | | At some point in the future, this bo won't necessarily be backed by a drm_mm_node, so use the start/size fields of the ttm_mem_reg instead. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| * drm/nouveau: wrap calls to ttm_bo_validate()Ben Skeggs2010-12-07
| | | | | | | | | | | | | | This will be used later to fixup bo.offset with a buffer's fixed GPU virtual address. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * drm/nouveau: make fifo.create_context() responsible for mapping control regsBen Skeggs2010-12-07
| | | | | | | | | | | | | | | | The regs belong to PFIFO, they're different for pretty much the same generations we need different PFIFO control for, and NVC0 is going to be even more different than the rest. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| * drm/nouveau: Spin for a bit in nouveau_fence_wait() before yielding the CPU.Francisco Jerez2010-12-07
| | | | | | | | | | | | | | | | Sleeping doesn't pay off for very short delays in comparison with the minimum granularity of schedule_timeout(). Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| * drm/nouveau: Synchronize with the user channel before GPU object destruction.Francisco Jerez2010-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There have been reports of PFIFO cache errors during context take down (fdo bug 31637). They are caused by some GPU objects being taken out while the channel is still potentially processing commands. Make sure that all the previous rendering has landed before releasing a GPU object.

| | | | | | | | | | | | | | | | | | nvxx_graph_isr is already taking care of it. In some cases this could've made you miss PGRAPH interrupts (e.g. when you were supposed to get several IRQs of the same kind in a row).

| * drm/nv50: rework PGPIO IRQ handling and hotplug detectionBen Skeggs2010-12-03
| | | | | | | | | | | | | | | | | | | | | | | | Allows callers to install their own handlers for when a GPIO line changes state (such as for hotplug detect). This also fixes a bug where we weren't acknowledging the GPIO IRQ until after the bottom half had run, causing a severe IRQ storm in some cases.
