2009-10-06drm/fb: add more correct 8/16/24/32 bpp fb support.Dave Airlie
The previous patches had some unwanted side effects, I've fixed the lack of 32bpp working, and fixed up 16bpp so it should also work. this also adds the interface to allow the driver to set a preferred console depth so for example low memory rn50 can set it to 8bpp. It also catches 24bpp on cards that can't do it and forces 32bpp. Tested on r100/r600/i945.

2009-10-05drm/fb: add setcmap and fix 8-bit support.Dave Airlie
This adds support for the setcmap api and fixes the 8bpp support at least on radeon hardware. It adds a new load_lut hook which can be called once the color map is setup. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-10-05drm/radeon/kms: respect single crtc cards, only create one crtc. (v2)Dave Airlie
Also add single crtc for RN50 chips. changes in v2: fix vblank init to respect single crtc flag fix r100 mode bandwidth to respect single crtc flag Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-25drm/kms: start adding command line interface using fb.Dave Airlie
[note this requires an fb patch posted to linux-fbdev-devel already] This uses the normal video= command line option to control the kms output setup at boot time. It is used to override the autodetection done by kms. video= normally takes a framebuffer as the first parameter, in kms it will take a connector name, DVI-I-1, or LVDS-1 etc. If no output connector is specified the mode string will apply to all connectors. The mode specification used will match down the probed modes, and if no mode is found it will add a CVT mode that matches. video=1024x768 - all connectors match a 1024x768 mode or add a CVT on video=VGA-1:1024x768, VGA-1 connector gets mode only. The same strings as used in current fb modedb.c are used, except I've added three more letters, e, D, d, e = enable, D = enable Digital, d = disable, which allow a connector to be forced into a certain state.

2009-09-11drm/radeon/kms: set fbdev_info for suspend/resumeDave Airlie
this hopefully will bring back suspend/resume under kms. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-08-31drm/kms: move driver specific fb common code to helper functions (v2)Dave Airlie
Initially I always meant this code to be shared, but things ran away from me before I got to it. This refactors the i915 and radeon kms fbdev interaction layers out into generic helpers + driver specific pieces. It moves all the panic/sysrq enhancements to the core file, and stores a linked list of kernel fbs. This could possibly be improved to only store the fb which has fbcon on it for panics etc. radeon retains some specific codes used for a big endian workaround. changes: fix oops in v1 fix freeing path for crtc_info Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-08-19drm/radeon/kms: memset the allocated framebuffer before using it.Dave Airlie
This gets rid of some ugliness, we shuold probably find a way for the GPU to zero this. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-29drm/radeon: set fb aperture sizes for framebuffer handoff.Dave Airlie
This will allow efi/vesa to handoff to radeon. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-29drm/radeon/kms: add initial colortiling support.Dave Airlie
This adds new set/get tiling interfaces where the pitch and macro/micro tiling enables can be set. Along with a flag to decide if this object should have a surface when mapped. The only thing we need to allocate with a mapped surface should be the frontbuffer. Note rotate scanout shouldn't require one, and back/depth shouldn't either, though mesa needs some fixes. It fixes the TTM interfaces along Thomas's suggestions, and I've tested the surface stealing code with two X servers and not seen any lockdep issues. I've stopped tiling the fbcon frontbuffer, as I don't see there being any advantage other than testing, I've left the testing commands in there, just flip the fb_tiled to true in radeon_fb.c Open: Can we integrate endian swapping in with this? Future features: texture tiling - need to relocate texture registers TXOFFSET* with tiling info. This also merges Michel's cleanup surfaces regs at init time patch even though it makes sense on its own, this patch really relies on it. Some PowerMac firmwares set up a tiling surface at the beginning of VRAM which messes us up otherwise. that patch is: Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-06-24drm/radeon: fix radeon kms framebuffer deviceJerome Glisse
smem.start is a physical address which kernel can remap to access video memory of the fb buffer. We now pin the fb buffer into vram by doing so we are loosing vram but fbdev need to be reworked to allow change in framebuffer address.

2009-06-15drm/radeon: introduce kernel modesetting for radeon hardwareJerome Glisse
Add kernel modesetting support to radeon driver, use the ttm memory manager to manage memory and DRM/GEM to provide userspace API. In order to avoid backward compatibility issue and to allow clean design and code the radeon kernel modesetting use different code path than old radeon/drm driver. When kernel modesetting is enabled the IOCTL of radeon/drm driver are considered as invalid and an error message is printed in the log and they return failure. KMS enabled userspace will use new API to talk with the radeon/drm driver. The new API provide functions to create/destroy/share/mmap buffer object which are then managed by the kernel memory manager (here TTM). In order to submit command to the GPU the userspace provide a buffer holding the command stream, along this buffer userspace have to provide a list of buffer object used by the command stream. The kernel radeon driver will then place buffer in GPU accessible memory and will update command stream to reflect the position of the different buffers. The kernel will also perform security check on command stream provided by the user, we want to catch and forbid any illegal use of the GPU such as DMA into random system memory or into memory not owned by the process supplying the command stream. This part of the code is still incomplete and this why we propose that patch as a staging driver addition, future security might forbid current experimental userspace to run. This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX (radeon up to X1950). Works is underway to provide support for R6XX, R7XX and newer hardware (radeon from HD2XXX to HD4XXX).
