From 881ee9889c8b98671c5491e43666bf5d4f78a180 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 2 Nov 2008 23:08:44 -0800 Subject: i915: Save/restore MCHBAR_RENDER_STANDBY on GM965/GM45 This register is set by the 2D driver to prevent lockups, and so it needs to be preserved across suspend/resume too. This makes my X200s work.

When userland detected that this ioctl was supported (by version number check), it used it in a racy way -- dispatch delayed swap, wait for vblank, continue rendering. As there was no mechanism for it to wait for the swap to finish, sometimes it would render before the swap and garbage would be displayed on the screen. By removing the ioctl and returning -EINVAL, userland returns to its previous, correct rendering path of waiting for a vblank then dispatching a swap. The only path that could have used this ioctl correctly was page flipping, which relied on only one client running and emitting wait-for-vblank-before-rendering in the command stream. That path also falls back correctly, at the performance cost of not being able to queue up rendering before the flip occurs.
