2017-03-09drm/qxl: Remove qxl_debugfs_remove_files()Noralf Trønnes1-1/+0
drm_debugfs_cleanup() now removes all minor->debugfs_list entries automatically, so it's not necessary to call drm_debugfs_remove_files().

2017-03-07qxl: drop mode_info.modes & related code.Gerd Hoffmann1-22/+0
very old qxl hardware revisions (predating qxl ksm support by a few years) supported a fixed list of video modes only. The list is still provided by the virtual hardware, for backward compatibility reasons. The qxl kms driver never ever looks at it, except for dumping it to the kernel log at load time in case debug logging is enabled. Drop that pointless code.

2017-01-19drm: qxl: Open code probing sequence for qxlGabriel Krisman Bertazi1-38/+2
This avoids using the deprecated drm_get_pci_dev() and load() hook interfaces in the qxl driver. The only tricky part is to ensure TTM debugfs initialization happens after the debugfs root node is created, which is done by moving that code into the debufs_init() hook. Tested on qemu with igt and running a WM on top of X. Changes since v1: - Drop verification for primary minor in qxl_debugsfs_init. Changes since V2: - Put new header together with other debugfs headers.

2016-07-12drm/qxl: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar1-5/+1
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.

2013-04-12drm: add new QXL driver. (v1.4)Dave Airlie1-0/+302
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.
