We never used initial_x/y or the force_encoder_id, so drop those fields and proide a basic description of the others. Really, the ELD bits belong in drm_display_info rather than directly in the connector, but that's a separate cleanup. Signed-off-by:

Now that we pull the right BIOS data out of the hat we need to use it when doing our panel setup. Signed-off-by:

The Oaktrail platform does not use the GCT/VBT format that is used by the Moorestowm (non PC legacy) equivalent device. It uses the BIOS tables which means an opregion and the like. The current code uses the wrong table which breaks things like the Fujitsu q550 tablets. Fix the table usage as a first step. The problem was found and diagnosed by Chia-I Wu Signed-off-by:

If we can't fit a page aligned display stride then it's not the end of the world for a normal font, so try half a page and work down sizes. Signed-off-by:

Add support for GTT based scrolling. Instead of pushing bits around we simply use the GTT to change the mappings. This provides us with a very fast way to scroll the display providing we have enough memory to allocate on 4K line boundaries. In practice this seems to be the case except for very big displays such as HDMI, and the usual configurations are netbooks/tablets. Signed-off-by:

If we are the console then a printk can hit us with a spin lock held (and in fact the kernel will do its best to take the console printing lock). In that case we cannot politely sleep when synching after an accelerated op but must behave obnoxiously to be sure of getting the bits out. Signed-off-by:

Initial changes to get backlight behaviour we want and to fix backlight crashes on suspend/resume paths. [Note: on some boxes this will now produce a warning about the backlight, this isn't a regression it's an unfixed but non harmful case I still need to nail] Signed-off-by:

First step in adding proper irq handling. We'll start with poulsbo support so make sure other chips don't touch drm_irq_install(). Signed-off-by:

This isn't actually usable - we simply don't have the vmap space on a 32bit system to do this stunt. Instead we will rely on the low level drivers limiting the console resolution as before. The real fix is for someone to write a page table aware version of the framebuffer console blit functions. Good university student project perhaps.. Signed-off-by:

Name the formats as DRM_FORMAT_X instead of DRM_FOURCC_X. Use consistent names, especially for the RGB formats. Component order and byte order are now strictly specified for each format. The RGB format naming follows a convention where the components names and sizes are listed from left to right, matching the order within a single pixel from most significant bit to least significant bit. The YUV format names vary more. For the 4:2:2 packed formats and 2 plane formats use the fourcc. For the three plane formats the name includes the plane order and subsampling information using the standard subsampling notation. Some of those also happen to match the official fourcc definition. The fourccs for for all the RGB formats and some of the YUV formats I invented myself. The idea was that looking at just the fourcc you get some idea what the format is about without having to decode it using some external reference. Signed-off-by:

Again this is similar but has some differences so we have a set of plug in support. This does make the driver bigger than is needed in some respects but the tradeoff for maintainability is huge. Signed-off-by:

Oaktrail (GMA600) is found on some tablet/slate PC type systems. It's a bit different to the GMA500 but similar enough it makes sense to plug it into the same driver. Signed-off-by:

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. Signed-off-by:
