2013-06-09drm/gma500/psb: Fix cursor gem obj referencing on psbPatrik Jakobsson1-6/+13
The internal crtc cursor gem object pointer was never set/updated since it was required to be set in the first place. Fixing this will make the pin/unpin count match and prevent cursor objects from leaking when userspace drops all references to it. Also make sure we drop the gem obj reference on failure. This patch only affects Poulsbo chips. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-06-09drm/gma500/psb: Unpin framebuffer on crtc disablePatrik Jakobsson1-0/+14
The framebuffer needs to be unpinned in the crtc->disable callback because of previous pinning in psb_intel_pipe_set_base(). This will fix a memory leak where the framebuffer was released but not unpinned properly. This patch only affects Poulsbo.

2013-03-17drm/gma500: Remove unnecessary function exposurePatrik Jakobsson1-2/+2
psb_intel_crtc_gamma_set() and psb_intel_crtc_destroy() aren't used outside of psb_intel_display.c right now so no need to expose them. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-03-17drm/gma500: Type clock limits directly into array and remove definesPatrik Jakobsson1-46/+20
This makes it easier to read. We do the same for cdv so it becomes more consistent as well. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-03-17drm/gma500: Calculate clock in one function instead of three identicalPatrik Jakobsson1-23/+5
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(). The same calculation is duplicated in cdv_intel_display.c as well so maybe we can share it later on. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>

2013-02-22gma500: Fix n, m1 and m2 clock limits for sdvo and lvdsPatrik Jakobsson1-6/+6
The values of n, m1 and m2 needs to be subtracted by 2 before writing them to the FP register. The dot clock calculation already thinks of these values in register form so we must also specify them as such.

2012-08-30gma500: Consider CRTC initially active.Forest Bond1-0/+3
[this one ideally should make 3.6 - it fixes the very annoying mode setting bug] This causes the pipe to be forced off prior to initial mode set, which roughly mirrors the behavior of the i915 driver. It fixes initial mode setting on my Intel DN2800MT (Cedarview) board. Without it, mode setting triggers an out-of-range error from the monitor for most modes, but only on initial configuration (i.e. they can be configured successfully from userspace after that).

2012-05-22gma500: handle poulsbo cursor restrictionPatrik Jakobsson1-7/+55
Poulsbo needs a physical address in the cursor base register. We allocate a stolen memory buffer and copy the cursor image provided by userspace into it. When/If we get our own userspace driver we can map this stolen memory directly. The patch also adds a mark in chip ops so we can identify devices that has this requirement.

2011-12-20drm: Replace pitch with pitches[] in drm_framebufferVille Syrjälä1-2/+2

2011-11-16gma500: Add Poulsbo supportAlan Cox1-0/+1431
This provides the specific code for Poulsbo, some of which is also used for the later chipsets. We support the GTT, the 2D engine (for console), and the display setup/management. We do not support 3D or the video overlays. In theory enough public info is available to do the video overlay work but that represents a large task. Framebuffer X will run nicely with this but do *NOT* use the VESA X server at the same time as KMS. With a Dell mini 10 things like Xfce4 are nice and usable even when compositing as the CPU has a good path to the memory.
