From 0665f9f852b4ac05f2f62046a169f0f5b9212317 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 22 Jul 2013 14:37:39 +1000 Subject: drm/qxl: add delayed fb operations Due to the nature of qxl hw we cannot queue operations while in an irq context, so we queue these operations as best we can until atomic allocations fail, and dequeue them later in a work queue. Daniel looked over the locking on the list and agrees it should be sufficent. The atomic allocs use no warn, as the last thing we want if we haven't memory to allocate space for a printk in an irq context is more printks.

In order to fix an issue with reservations we need to create the releases as pre-pinned objects, this changes the placement interface and bo creation interface to allow creating pinned objects to save nested reservations later. This is just a stepping stone to main fix which follows to actually fix how qxl deals with reservations.

It now allocates the necessary objects then does a complete reservation pass on them to avoid deadlocks. c) it had two lists per release tracking objects, unnecessary complicating the reservation process. This patch removes the dual object tracking, adds reservations ticket support to the release and fence object handling. It then ports the internal fb drawing code and the userspace facing ioctl to use the new interfaces properly, along with cleanup up the error path handling in some codepaths.
