Until now the ingenic-drm driver supported the same pixel formats on the F0 and F1 planes, and across all SoCs. However, the F0 plane does support paletted 8bpp, while the F1 plane doesn't. Furthermore, the three SoCs currently supported all have different pixel formats available; 24bpp was added in JZ4725B, 30bpp was added in JZ4770. Prepare the inclusion of paletted 8bpp, 24bpp and 30bpp support by having separate pixel format lists for F0 and F1 planes. Signed-off-by:

Instead of calling dmam_alloc_coherent() once for each 4-bit DMA hardware descriptor, we can have them both in a physical memory page, as long as they are aligned to 16 bytes. This reduces memory consumption, and will make it easier to add more DMA descriptors in the future. Note that the old code would not create the F0 descriptor on SoCs that don't support multiple planes. We don't care, because: - we don't use more memory by allocating two descriptors instead of a single one; - the only SoC that does not support multiple planes (JZ4740) still has two independent DMA channels, for an unknown reason.

Add support for static memory reserved from Device Tree. Since we're using GEM buffers backed by CMA, it is interesting to have an option to specify the CMA area where the GEM buffers will be allocated. v2: Don't abort probe if reserved memory cannot be obtained. The driver will still work fine provided the kernel configuration is sane. Signed-off-by: -

Old Ingenic SoCs can overclock very well, up to +50% of their nominal clock rate, whithout requiring overvolting or anything like that, just by changing the rate of the main PLL. Unfortunately, all clocks on the system are derived from that PLL, and when the PLL rate is updated, so is our pixel clock. To counter that issue, we make sure that the panel is in VBLANK before the rate change happens, and we will then re-set the pixel clock rate afterwards, once the PLL has been changed, to be as close as possible to the pixel rate requested by the encoder. v2: Add comment about mutex usage Signed-off-by:

This is one of the last users of compat_alloc_user_space() and copy_in_user(). The actual handler is implemented in the same file and could be shared, but as I couldn't test this properly I leave the native case alone and just make a straight copy of it for the compat case, with a minimum set of modifications.

No driver implements FBIOSCURSOR, so this function has no purpose and can be removed. Apparently it was added in linux-2.1.44 to handle compatibility for drivers/sbus/char/sunfb.c but lost its purpose when that driver got rewritten in linux-2.5.63. Signed-off-by:

This function is one of the remaining users of compat_alloc_user_space() and copy_in_user(). Clean it up by copying to a local data structure copy instead, which also leads to more readable code. Signed-off-by:

Most drivers that use VRAM helpers have only a few MiB of framebuffer memory available. To reduce fragmentation, new BOs are now put into system memory by default. Only pin operations are allowed to move BOs into VRAM. v2: * rebased onto latest drm-tip Signed-off-by:

Several GEM and PRIME callbacks have been deprecated in favor of per-instance GEM object functions. Remove the callbacks as they are now unused. The only exception is .gem_prime_mmap, which is still in use by several drivers. What is also gone is gem_vm_ops in struct drm_driver. All drivers now use struct drm_gem_object_funcs.vm_ops instead. While at it, the patch also improves error handling around calls to .free and .get_sg_table callbacks. v3: * restore default call to drm_gem_prime_export() in drm_gem_prime_handle_to_fd() * return -ENOSYS if get_sg_table is not set * drop all checks for obj->funcs * clean up TODO list and documentation v2: * update related TODO item (Sam) Signed-off-by:

The xlnx driver uses CMA helpers with default callback functions. Initialize the driver structure with the rsp CMA helper macro. The driver is being converted to use GEM object functions as part of this change. Two callbacks, .dumb_destroy and .gem_prime_import, were initialized to their default implementations, so they are just kept empty now. v2: * initialize with DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE (Laurent) Signed-off-by:

The core move code currently handles use_tt moves, for radeon this was being handled also in the driver, but not using the same paths. If moving between TT/SYSTEM (all the use_tt paths on radeon) use the core move function. Eventually the core will be flipped over to calling the driver. Reviewed-by:
