2014-03-18uxa: Implement minimal flushing for bdw+Chris Wilson
Based on the patch by Kenneth Graunke, "Several places (such as intel_cache_expire) call intel_emit_batch_flush, so it needs to work on Broadwell. Sometimes the batch is empty, in which case current_batch may not yet be BLT_RING. The PIPE_CONTROL code has not been ported to work on Broadwell, so trying to do a render ring flush will hang the GPU. It also doesn't make any sense to do a render ring flush, given that we never use the render ring for UXA on Broadwell."

2014-03-18uxa: Add support for server managed fds (via intel_device)Chris Wilson
Based on the patch by Hans de Goede, this removes the handling of drmOpen() and DRM_MASTER from within uxa and instead uses the common routines. This reduces the duplicate code from within uxa, and enables new features such as server managed fds. Cc: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-03-13uxa: Enable BLT acceleration on Broadwell.Kenneth Graunke
This supports solid, copy, put_image, and get_image acceleration via the BLT engine. RENDER acceleration (composite) and Xv would be piles of work, which is not worth doing since SNA exists, and Glamor is coming. Signed-off-by: Kenneth Graunke <kenneth@whitecape.org>

2014-02-15backlight: Amalgamate hardcoded priority tablesChris Wilson
Our fallback path for finding the backlight interface uses a hardcoded table of known backlight controllers in proirity order. Rather than maintain this table twice in the midst of the KMS logic, push it to the new set of common backlight routines. This incorporates bugfixes from SNA to handle unknown backlights, but usable, gracefully. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-02-15intel: Add a helper for setting backlight without root rightsChris Wilson
Once the xserver stops running as root on kms capabable systems, we will need some other way to access the backlight. The approach taken in this patch moves most of the heavy lifting to a helper that runs with root privileges and pipes our requested brightness into the sysfs backlight interface. Where required, we use pkexec to launch the helper with the elevated privilege. v2: Amalgamate much more of the duplicate code. Keep the daemon and pipe alive for the lifetime of the backlight interface. Provide an alternative for systems without PolicyKit.

2014-02-13uxa: Check for access to backlight interfaceChris Wilson
Before attaching properties to any connector, check that we can indeed control the backlight through the sysfs interface by doing an access check. If the xserver is started without root privileges, we cannot write through /sys/class/backlight and so should take care not to advertise that we can.

2014-02-13Revert "uxa: Do not change DPMS mode on unconnected outputs"Chris Wilson
This reverts commit 4497212307dee5e35bc6836201738a2fdb559020. Unfortunately, this simple fix does not work for UXA as DPMS is used by the xserver to turn off CRTCs and outputs. Since UXA does not implement CRTC DPMS, this commit causes us to fail to turn off outputs. The kernel has been fixed up in the meantime and that commit has been recommended to be backported to all stable kernels: commit c9976dcf55c8aaa7037427b239f15e5acfc01a3a Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Sep 29 19:15:07 2013 +0100 drm/i915: Only apply DPMS to the encoder if enabled so it should be safe for UXA to rely on its old behaviour.

2014-01-17Provide DRI2DriverVDPAU for future compatibilityRinat
Since 2010, DRI2 supports multiple driver names. That was added to ease selection of appropriate driver by libvdpau. As for today, intel driver support only DRI2DriverDRI (== 0), but not DRI2DriverVDPAU (== 1). Although there is no any hardware-specific VDPAU driver for intel video adapters at the moment, it would be easier to use generic drivers like libvdpau-va-gl by creating symlink named libvdpau_i965.so.1. That way appropriate driver will be selected in run time automatically: libvdpau_i965.so.1 on i965 equipped machines, and libvdpau_nvidia.so.1 on nvidia equipped ones. [ickle: Whilst I think this is a workaround for a brainfart in libvdpau that it defaults to libvdpau_nvidia.so rather than first to libdvpau_${DRI2DriverDRI} and then to a hardcoded libvdpau_backend.so, I have no better solution, and this does seem in accordance with the spec.] Signed-off-by: Rinat <ibragimovrinat@mail.ru> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=73507
2014-01-06uxa: Always treat DPMSModeSuspend/Standby similar to DPMSModeOffChris Wilson
As we assume that Suspend, Standby alias to Off and disable the crtc when switching to any mode other than On, we need to also perform the backlight updates for Suspend,Standby prior to passing the DPMS value onto the kernel.

2014-01-06uxa/dri: Pixmap are offscreen and not attached to any displayChris Wilson
As the code current assumes that pixmaps are located at screen origin (0,0), it assumes that they are all on the first CRTC. However, since they are offscreen, this leads to such complications as attempting to emit vsync swapbuffers, and even worse attempting to swap a GLXPixmap onto the scanout following a DRI2SwapBuffers.

2013-10-13uxa: Check for allocation failure in i915 videoChris Wilson

2013-10-13uxa: Abort CreateScreenResources after allocation failureChris Wilson
One of UXA's invarients is that the ScreenPixmap is complete (i.e. has an intel_pixmap private with a bo attached). If we fail to create that private during CreateScreenResources we will die very soon afterwards, so just report the failure and shutdown gracefully.

2013-10-03intel: Remove dependence upon having PciInfoChris Wilson
After some probing mechanisms, we may end up with a valid device without knowing its PCI address a priori. Having a valid device, we can just query it for the correct device id, and can safely abort any path that requires PCI information that we don't have. (Those paths are not valid under such hosting anyway - if it may be required, we could reconstruct the address.) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
