2017-06-23drm/qxl: fix __user annotationsGerd Hoffmann1-3/+3
Drop them from u64 fields, tag local variables correctly instead. While being at it switch the code to use u64_to_user_ptr().

2016-04-27drm/qxl: remove XXX comment from the UAPI headerEmil Velikov1-1/+0
One cannot rename the struct at this point, so might as well remove the comment. Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Dave Airlie <airlied@redhat.com> Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2015-12-10drm: fix inclusion of drm.h in qxl_drm.hGabriel Laskar1-2/+1
Using `#include "drm.h"` instead of `#include <drm/drm.h>` allow drm headers to be moved in another directory without changes, like for the libdrm imports.

2013-04-12drm: add new QXL driver. (v1.4)Dave Airlie1-0/+152
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 This requires a newer version of the QXL userspace driver, so shouldn't be enabled until that has been placed into your distro of choice.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.
