2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen1-184/+0
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

2008-04-28gxfb/lxfb: detect framebuffer size using an MSR if VSA2 isn't availableAndres Salomon1-1/+17
If there's no VSA2 (ie, if we're using tinybios or OpenFirmware), use the GLIU's P2D Range Offset Descriptor to determine how much memory we have available for the framebuffer. Originally based on a patch by Jordan Crouse. Tested with OpenFirmware; Pascal informs me that tinybios has a stub that fills in P2D_RO0.

2008-04-28gxfb: stop sharing code with gx1fbAndres Salomon1-14/+7
We want to stop sharing stuff with gx1fb; it makes little sense. There were fields in geodefb_par that weren't being used, there was little point to the DC/VP ops callbacks, etc. This implements the following: - Create gxfb_par (based on geodefb_par), place it in gxfb.h - Drop display_gx.h and video_gx.h. The last few patches moved most stuff into gxfb.h anyways, so there was very little left. - Drop the geode_{dc,vid}_ops stuff. Un-static functions, add declarations to gxfb.h.

2008-04-28gxfb: clean up register definitionsAndres Salomon1-13/+15
This does the following in preparation for register saving: - moves the register definitions from video_gx.h and display_gx.h into gxfb.h. - renames GX_* registers to match their section (ie, VP_). - renames register bitfields to match the data sheet (ie, DC_DCFG_TGEN -> DC_DISPLAY_CFG_TGEN). - for DC registers, rather than defining to specific addresses, use an enum to number them sequentially and just multiply by 4(bytes) to access them (in read_dc/write_dc). - for VP and FP registers, use an enum and multiple by 8 (bytes). They're 64bit registers. Signed-off-by: Andres Salomon <dilinger@debian.org> Cc: Jordan Crouse <jordan.crouse@amd.com> Cc: "Antonino A.

2008-04-28gxfb: create DC/VP/FP-specific handlers rather than using readl/writelAndres Salomon1-21/+27
This creates read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for reading and updating those registers. It creates gxfb.h to house these. We also drop a no-op readl() from gx_set_mode. Other than that, there should be no functionality change. Signed-off-by: Andres Salomon <dilinger@debian.org> Cc: Jordan Crouse <jordan.crouse@amd.com> Cc: "Antonino A.

2008-04-28gxfb: replace FBSIZE config option with a module parameterAndres Salomon1-7/+0
Use a command line option (vram) rather than hardcoding the vram size. LxFB already does this; it's useful for machines that can't query the BIOS for fb size. This patch originated from David Woodhouse, was modified by Jordan Crouse, and was then modified further by me. This also adds some gxfb documentation in Documentation/fb.

2006-12-08[PATCH] gxfb: Fixups for the AMD Geode GX framebuffer driverJordan Crouse1-0/+8
We cannot assume that the BIOS will be correctly setting up the hardware, so set some bits in various display registers to enable video output. Allow an advanced user to specify a frambuffer size, rather then probing the BIOS. All of these fixes were prompted by the OLPC effort.

2006-03-27[PATCH] fbdev: framebuffer driver for Geode GXDavid Vrabel1-0/+156
A framebuffer driver for the display controller in AMD Geode GX processors (Geode GX533, Geode GX500 etc.). Tested at 640x480, 800x600, 1024x768 and 1280x1024 at 8, 16, and 24 bpp with both CRT and TFT. No accelerated features currently implemented and compression remains disabled. This driver requires that the BIOS (or the SoftVG/Firmbase code in the BIOS) has created an appropriate virtual PCI header.
