2013-04-18drm/i915: Abstract PPGTT enablingBen Widawsky
Since we've already set up a nice vtable to abstract other PPGTT functions, also abstract the actual register programming to enable things. This function will probably need to change a bit as we implement real processes. v2: Resolve conflicts due to patch series reordering.

2013-04-18drm/i915: generalize pte vs. register BAR allocationBen Widawsky
All gen6+ parts so far have 1 BAR which holds both the register space and the GTT PTEs. Up until now, that was a 4MB BAR with half allocated to each. I have a strong hunch (wink, nod, wink) that future gens will also keep a similar 50-50 split though the sizes may change. To help this along change the code to obey the rule of half the total size instead of a hard-coded 2MB.

2013-04-18drm/i915: Use MLC (l3$) for context objectsChris Wilson
Enabling context support increases SwapBuffers latency by about 20% (measured on an i7-3720qm). We can offset that loss slightly by enabling faster caching for the contexts. As they are not backed by any particular cache (such as the sampler or render caches) our only option is to select the generic mid-level cache. This reduces the latency of the swap by about 5%. Oddly this effect can be observed running smokin-guns on IVB at 1280x1024: Using BLT copies for swaps: 151.67 fps Using Render copies for swaps (unpatched): 141.70 fps With contexts disabled: 150.23 fps With contexts in L3$: 150.77 fps Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ben Widawsky <ben@bwidawsk.net> Cc: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-04-18drm/i915: Fix SDVO connector and encoder get_hw_state functionsEgbert Eich
The connector associated with the encoder is considered active when the output associtated with this connector is active on the encoder. The encoder itself is considered active when either there is an active output on it or the respective SDVO channel is active. Having active outputs when the SDVO channel is inactive seems to be inconsistent: such states can be found when intel_modeset_setup_hw_state() collects the hardware state set by the BIOS. This inconsistency will be fixed in intel_sanitize_crtc() (when intel_crtc_update_dpms() is called), this however only happens when the encoder is associated with a crtc.

2013-04-17drm/exynos: change the method for getting the interruptVikas Sajjan
Replaces the "platform_get_resource() for IORESOURCE_IRQ" with platform_get_resource_byname(). Both in exynos4 and exynos5, FIMD IP has 3 interrupts in the order: "fifo", "vsync", and "lcd_sys". But The FIMD driver expects the "vsync" interrupt to be mentioned as the 1st parameter in the FIMD DT node. So to meet this expectation of the driver, the FIMD DT node was forced to be made by keeping "vsync" as the 1st paramter. For example in exynos4, the FIMD DT node has interrupt numbers mentioned as <11, 1> <11, 0> <11, 2> keeping "vsync" as the 1st paramter. This patch fixes the above mentioned "hack" of re-ordering of the FIMD interrupt numbers by getting interrupt resource of FIMD by using platform_get_resource_byname().

2013-04-16drm: Perform ioctl command validation on the stored kernel valuesChris Wilson
Userspace is free to pass in any command bits it feels like through the ioctl cmd, and for example trinity likes to fuzz those bits to create conflicting commands. So instead of relying upon userspace to pass along the correct IN/OUT flags for the ioctl, use the flags as expected by the kernel. This does have a side-effect that NULL pointers can not be substituted by userspace in place of a struct. This feature was not being used by any driver, but instead exposed all of the command handlers to a user triggerable OOPS.

2013-04-15drm/gma500: Check connector status before restoring sdvoPatrik Jakobsson
This patch fixes a bug introduced by: commit 749387dc8d8270b279f27a0a794cdf4f4a4aa774 Author: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Date: Sun Apr 7 16:35:50 2013 +0200 drm/gma500: Fix hibernation problems on sdvo encoders The bug is triggered when we do a mode set on a sdvo encoder with all connectors in the disconnected state. A crtc is considered enabled by drm even though all of its connectors are disconnected. Work around this by adding a check in our sdvo restore function. Also remove the unneeded dpms on. Prepare and Commit will take care of that. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>

2013-04-12drm: cleanup: use drm_framebuffer_reference instead of a kref_getarchit taneja
drm_framebuffer_lookup() does a kref_get() for the framebuffer if it finds one corresponding to the fb id passed to it. Use drm_framebuffer_reference() instead for clarity since it's the function used in other places to take a reference.

2013-04-12drm: add new QXL driver. (v1.4)Dave Airlie
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.
