* drm/qxl: reapply cursor after SetCrtc callsRay Strode2016-09-20
| | | | | | | | | | | | | | | | | | | The qxl driver currently destroys and recreates the qxl "primary" any time the first crtc is set. A side-effect of destroying the primary is mouse state associated with the crtc is lost, which leads to disappearing mouse cursors on wayland sessions. This commit changes the driver to reapply the cursor any time SetCrtc is called. It achieves this by keeping a reference to the cursor bo on the qxl_crtc struct.

* drm/qxl: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar2016-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | System workqueues have been able to handle high level of concurrency for a long time now and there's no reason to use dedicated workqueues just to gain concurrency. Since the workqueue in the QXL graphics device driver is involved in freeing and processing the release ring (workitem &qdev->gc_workqxl, maps to gc_work which calls qxl_garbage_collect) and is not being used on a memory reclaim path, dedicated gc_queue has been replaced with the use of system_wq. Unlike a dedicated per-cpu workqueue created with create_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantees unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. flush_work() has been called in qxl_device_fini() to ensure that there are no pending tasks while disconnecting the driver.

| * drm/qxl: fix cursor position with non-zero hotspotJohn Keeping2016-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPICE protocol considers the position of a cursor to be the location of its active pixel on the display, so the cursor is drawn with its top-left corner at "(x - hot_spot_x, y - hot_spot_y)" but the DRM cursor position gives the location where the top-left corner should be drawn, with the hotspot being a hint for drivers that need it. This fixes the location of the window resize cursors when using Fluxbox with the QXL DRM driver and both the QXL and modesetting X drivers.

* drm/qxl: validate monitors config modesJonathon Jongsma2015-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to some recent changes in drm_helper_probe_single_connector_modes_merge_bits(), old custom modes were not being pruned properly. In current kernels, drm_mode_validate_basic() is called to sanity-check each mode in the list. If the sanity-check passes, the mode's status gets set to to MODE_OK. In older kernels this check was not done, so old custom modes would still have a status of MODE_UNVERIFIED at this point, and would therefore be pruned later in the function. As a result of this new behavior, the list of modes for a device always includes every custom mode ever configured for the device, with the largest one listed first. Since desktop environments usually choose the first preferred mode when a hotplug event is emitted, this had the result of making it very difficult for the user to reduce the size of the display. The qxl driver did implement the mode_valid connector function, but it was empty. In order to restore the old behavior where old custom modes are pruned, we implement a proper mode_valid function for the qxl driver. This function now checks each mode against the last configured custom mode and the list of standard modes. If the mode doesn't match any of these, its status is set to MODE_BAD so that it will be pruned as expected.

* qxl: add a connector property to denote hotplug should rescan modes.Dave Airlie2013-11-06
| | | | | | | | | | | | | | | | | So GNOME userspace has an issue with when it rescans for modes on hotplug events, if the monitor has no EDID it assumes that nothing has changed on EDID as with real hw we'd never have new modes without a new EDID, and they kind off rely on the behaviour now, however with virtual GPUs we would like to rescan the modes and get a new preferred mode on hotplug events to handle dynamic guest resizing (where you resize the host window and the guest resizes with it). This is a simple property we can make userspace watch for to trigger new behaviour based on it, and can be used to replaced EDID hacks in virtual drivers.

| * qxl: convert qxl driver to proper use for reservationsDave Airlie2013-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent addition of lockdep support to reservations and their subsequent use by TTM showed up a number of potential problems with the way qxl was using TTM objects. a) it was allocating objects, and reserving them later without validating underneath the reservation, which meant in extreme conditions the objects could be evicted before the reservation ever used them. b) it was reserving objects straight after allocating them, but with no ability to back off should the reservations fail. 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.

| * drm/qxl: add delayed fb operationsDave Airlie2013-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Dave Airlie <airlied@redhat.com>

* drm: add new QXL driver. (v1.4)Dave Airlie2013-04-11
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.
