| * | | | | | | | | | | | | | | | | | | | | | | drm/i915: Emit a request to clear a flushed and idle ring for unbusy boChris Wilson2010-12-07

This is expected, for example, by occlusion queries for which mesa will wait upon (whilst running glean) before issuing more batches and so the normal activity upon the ring is suspended and we need to emit a request to clear the idle ring.

The consequence of this would be that across a simple DPMS off/on for a non-native mode, without an intervening modeset, the panel fitter would remain disabled and the output would shift on the panel.

Instead, we need to unwind, drop the dev->struct_mutex, copy all the relocation entries to a vmalloc array (to avoid any potential circular deadlocks when resolving the pagefault), retake the mutex and then apply the relocations. Afterwards, we need to again drop the lock and copy the vmalloc array back to userspace. v2: Incorporate feedback from Daniel Vetter.

At the moment, the cursor is restored before the aperture and modes are fully setup causing some invalid access during resume, such as: PGTBL_ER: 0x00040000 Invalid GTT entry during Cursor Fetch Fix this by only performing cursor register save/restore under UMS where it is done in the correct sequence.

This commit switches the default case to handle the newest chipsets. This also makes nv4e touch the "extra" tiling regs. "nv" doesn't touch them for C51 but traces of the NVIDIA binary driver show it being done there. I couldn't find NV41/NV45 traces to confirm the behaviour there, but an educated guess was taken at each of them. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
