2020-11-06drm/qxl: replace idr_init() by idr_init_base()Deepak R Varma1-2/+2
idr_init() uses base 0 which is an invalid identifier for this driver. The idr_alloc for this driver uses 1 as start value for ID range. The new function idr_init_base allows IDR to set the ID lookup from base 1. This avoids all lookups that otherwise starts from 0 since 0 is always unused / available.

2020-03-31drm/qxl: Use correct notify port address when creating cursor ringHuacai Chen1-1/+1
The command ring and cursor ring use different notify port addresses definition: QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR. However, in qxl_device_init() we use QXL_IO_NOTIFY_CMD to create both command ring and cursor ring. This doesn't cause any problems now, because QEMU's behaviors on QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR are the same. However, QEMU's behavior may be change in future, so let's fix it. P.S.: In the X.org QXL driver, the notify port address of cursor ring is correct.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-1/+1
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2018-06-12treewide: kmalloc() -> kmalloc_array()Kees Cook1-2/+2
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

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.

2013-11-06drm/qxl: support 64bit surface barGerd Hoffmann1-7/+25
qxl devices can have a 64bit surface bar, which is quite handy if you need a bit more surface memory. So try to use it if it is present. Note that this bar might be mapped above 4g. QEMU command line to check that out: qemu-system-x86_64 -m 4g \ -vga qxl -global qxl-vga.vram64_size_mb=512 \ $otheroptions Signed-off-by: Gerd Hoffmann <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
2013-07-05qxl: use drm helper hotplug supportDave Airlie1-0/+3
This uses the helper to deal with hotplug so fbdev gets included. Signed-off-by: Dave Airlie <[email protected]>
2013-07-05qxl: prepare memslot code for suspend/resumeDave Airlie1-4/+17
this splits out initing the hw memslots from the guest info, and creates an entrypoint for s/r to use. Signed-off-by: Dave Airlie <[email protected]>

/usr/lib/gcc/x86_64-linux-gnu/4.7/include/stddef.h:414:9: sparse: preprocessor token offsetof redefined include/linux/stddef.h:17:9: this was the original definition >> drivers/gpu/drm/qxl/qxl_drv.c:49:5: sparse: symbol 'qxl_modeset' was not declared.

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.
