* drm/radeon/kms: balance asic_reset functionsAlex Deucher2011-01-173-18/+20
| | | | | | | | | | | | | | | | | | First, we were calling mc_stop() at the top of the function which turns off all MC (memory controller) clients, then checking if the GPU is idle. If it was idle we returned without re-enabling the MC clients which would lead to a blank screen, etc. This patch checks if the GPU is idle before calling mc_stop(). Second, if the reset failed, we were returning without re-enabling the MC clients. This patch re-enables the MC clients before returning regardless of whether the reset was successful or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After reordering the sequence of relocating objects, commit 6fe4f1404, we can no longer rely on seeing all reloc targets prior to performing the relocation. As a result we were ignoring the need to flush objects from the render cache and invalidate the sampler caches, resulting in rendering glitches. So we need to clear the relocation domains earlier.

| * | drm/i915: Fix error handler to capture the first batch after the seqnoChris Wilson2011-01-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whilst we had no older batches on the active list, everything was fine. However, if the GPU is free running and the requests are only being reaped by the periodic retirer, than the current seqno may not be at the start of the list. In this case we need to select the first batch after the last seqno written by the gpu and not inclusive of the seqno. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

This is useful in case we ever need to map an object later. However, if you have a large object that can consume the entire mappable region of the GTT this prevents the batchbuffer from fitting and so causing an error. Instead allocate all those that require a mapping up front in order to improve the likelihood of finding sufficient space to bind them. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

* | | | | | drm/i915: Enforce write ordering through the GTTChris Wilson2011-01-112-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to ensure that writes through the GTT land before any modification to the MMIO registers and so must impose a mandatory write barrier when flushing the GTT domain. This was revealed by relaxing the write ordering by experimentally mapping the registers and the GATT as write-combining. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As has_gem is unconditionally set to true, the conditional immediately following that assignment is superfluous. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
