2013-04-10gma500:fix build failure for 3.9-rc5Xiong Zhou1-4/+9
Last version of this patch is not clear enough and X86 duplicated. This patch fixes build failure of v3.9-rc5 and rc6. When config ACPI_VIDEO as m, DRM_GMA500 as y, here comes the failure. GMA5/600 needs acpi_video just like nouveau. And some tab type fix by the way. Failure message: drivers/built-in.o: In function `psb_driver_load': kernel-3.9-rc5/drivers/gpu/drm/gma500/psb_drv.c:340: \ undefined reference to `acpi_video_register' make: *** [vmlinux] Error 1 Signed-off-by: Xiong Zhou <jencce.kernel@gmail.com> Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-04-07drm/gma500: Fix hibernation problems on sdvo encodersPatrik Jakobsson1-0/+34
The state of the SDVO chip is more difficult to save than the LVDS so we do a full mode set on the crtc to get SDVO operational again. The SDVOB/C register is also stored just in case we have special bits set in the future. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>

2013-04-07drm/gma500: Activate the gtt rebuild on suspend/resumePatrik Jakobsson1-0/+2
This patch activates the rebuilding of the gtt. Currently we reinitialize the gtt by inserting the stolen pages again and map the rest to our scratch page. Then we go about restoring the needed ranges. This is a bit overkill but right now we don't have that much to restore so better safe than sorry.

i9xx_clock() and i8xx_clock() did the same calc and psb_intel_clock() just called i9xx_clock() so just move it all into psb_intel_clock().

To fix up the very slow unplug issues we might want to fire up a 2nd detect cycle a few hundred ms after each hotplug. But for now at least make displays work again. I somewhat suspect that this is confined to HDMI connectors, since all the machines I have with DP+ outputs work correctly.

2013-02-22drm/tegra: Add list of framebuffers to debugfsThierry Reding1-0/+44
This list is most useful to inspect whether framebuffer reference counting works as expected. The code is loosely based on the i915 implementation. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>

2013-02-22drm/tegra: Split DC_CMD_STATE_CONTROL register writeThierry Reding1-2/+3
The Tegra TRM says that the ACT_REQ and UPDATE fields cannot be programmed at the same time so they are updated in two consecutive writes instead. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-22drm/tegra: Implement page-flipping supportThierry Reding4-0/+82
All the necessary support bits like .mode_set_base() and VBLANK are now available, so page-flipping case easily be implemented on top. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-22drm/tegra: Implement VBLANK supportThierry Reding3-17/+91
Implement support for the VBLANK IOCTL. Note that Tegra is somewhat special in this case because it doesn't use the generic IRQ support provided by the DRM core (DRIVER_HAVE_IRQ) but rather registers one interrupt handler for each display controller. While at it, clean up the way that interrupts are enabled to ensure that the VBLANK interrupt only gets enabled when required. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-22drm/tegra: Implement .mode_set_base()Thierry Reding1-0/+32
The sequence for replacing the scanout buffer is much shorter than a full mode change operation so implementing this callback considerably speeds up cases where only a new framebuffer is to be scanned out. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-22drm/tegra: Add plane supportThierry Reding3-95/+372
Add support for the B and C planes which support RGB and YUV pixel formats and can be used as overlays or hardware cursor. Currently 32-bit XRGB as well as UYVY, YUV420 and YUV422 pixel formats are advertised. Other formats should be easy to add but these are the most common ones and should cover the majority of use-cases. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-22drm/tegra: Remove bogus tegra_framebuffer structureThierry Reding2-12/+1
Tegra uses the CMA FB helpers so framebuffers passed to the driver need to use the corresponding functions to access the underlying GEM objects. This used to work because struct tegra_framebuffer was sufficiently similar to struct drm_fb_cma but that isn't guaranteed to stay that way. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-22drm: Add consistency check for page-flippingThierry Reding2-0/+13
Driver implementations of the drm_crtc's .page_flip() function are required to update the crtc->fb field on success to reflect that the new framebuffer is now in use. This is important to keep reference counting on the framebuffers balanced. While at it, document this requirement to keep others from falling into the same trap.

The modes are only used from within drm_edid.c so we move them there to avoid creating duplicates by multiple inclusion of drm_edid_modes.h. As a side-effect we can also get rid of a few variables that keep track of the number of entries in the tables and use ARRAY_SIZE() instead.

2013-02-21drm/i915: Handle untiled planes when computing their offsetsChris Wilson3-22/+34
We trim the fb to fit the CRTC by computing the offset of that CRTC to its nearest tile_row origin. This allows us to use framebuffers that are larger than the CRTC limits without additional work. However, we failed to compute the offset for a linear framebuffer correctly as we treated its x-advance in whole tiles (instead of the linear increment expected), leaving the CRTC misaligned with its contents.

This patch fixes wrong pointer access issue to filp->f_op and filp->private_data.
