| * | drm/qxl: Remove release_lock stupidity | Maarten Lankhorst | 2014-09-03 |
| | | | | | | | | | The locking of release_lock was stupid; t should have been be called with fence_lock_irq if it was legitimately used. Unfortunately it never protected anything except the fence implementation correctly. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> | ||

| * | drm/qxl: rework to new fence interface | Maarten Lankhorst | 2014-09-02 |
| | | | | | | | | | | | Final driver! \o/ This is not a proper dma_fence because the hardware may never signal anything, so don't use dma-buf with qxl, ever. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> | ||

| * | drm: add new QXL driver. (v1.4) | Dave Airlie | 2013-04-11 |
| QXL is a paravirtual graphics device used by the Spice virtual desktop interface. The drivers uses GEM and TTM to manage memory, the qxl hw fencing however is quite different than normal TTM expects, we have to keep track of a number of non-linear fence ids per bo that we need to have released by the hardware. The releases are freed from a workqueue that wakes up and processes the release ring. releases are suballocated from a BO, there are 3 release categories, drawables, surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling. The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface ids. This requires a newer version of the QXL userspace driver, so shouldn't be enabled until that has been placed into your distro of choice. Authors: Dave Airlie, Alon Levy v1.1: fixup some issues in the ioctl interface with padding v1.2: add module device table v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq, don't try flush release ring (broken hw), fix -modesetting. v1.4: fbcon cpu usage reduction + suitable accel flags.
