* lxfb/gxfb: when blanking with FB_BLANK_POWERDOWN, also turn off the CRTAndres Salomon2008-04-281-8/+10
| | | | | | | | | | | The Display Control's CRT_EN can be shut off when we enter FB_BLANK_POWERDOWN in an attempt to save additional power.

* gxfb: stop sharing code with gx1fbAndres Salomon2008-04-281-14/+6Star
| | | | | | | | | | | | | | | | | | 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.

* gxfb: move MSR bit fields into gxfb.hAndres Salomon2008-04-281-2/+2
| | | | | | | | | | | This continues the gxfb header cleanups. MSRs are defined in geode.h; the specific bits we care about are defined in gxfb.h.

* gxfb: clean up register definitionsAndres Salomon2008-04-281-46/+46
| | | | | | | | | | | | | | | | | | | | 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.

* gxfb: create DC/VP/FP-specific handlers rather than using readl/writelAndres Salomon2008-04-281-20/+21
| | | | | | | | | | | | | | 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.

* gxfb: don't enable the CRT DACs when we are in flatpanel modeJordan Crouse2008-04-281-15/+17
| | | | | | | | | | | | | When the FP strap is enabled, don't turn on the CRT DACs - that will save about 35 mA of power. Updated/cleaned up by Andres Salomon.

* gxfb: set the right registers to tweak the sync polarityJordan Crouse2008-04-281-6/+10
| | | | | | | | | | | | | | | While running in flatpanel mode it is important to change the FP sync bits (VG register 0x408) rather then the CRT sync bits (VG register 0x008). This patch keeps the CRT sync bits at default when a flatpanel exists. Note that this also fixes inverted logic; we want CRT_VSYNC_POL to be set (ie, vsync is normally high) when FB_SYNC_VERT_HIGH_ACT is unset.

* x86: geode: MSR cleanupAndres Salomon2008-04-281-2/+3
| | | | | | | | | | | | | | | | | This cleans up a few MSR-using drivers in the following manner: - Ensures MSRs are all defined in asm/geode.h, rather than in misc places - Makes the naming consistent; cs553[56] ones begin with MSR_, GX-specific ones start with MSR_GX_, and LX-specific ones start with MSR_LX_. Also, make the names match the data sheet. - Use MSR names rather than numbers in source code - Document the fact that the LX's MSR_PADSEL has the wrong value in the data sheet. That's, uh, good to note.

* x86: convert cpuinfo_x86 array to a per_cpu arrayMike Travis2007-10-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | cpu_data is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpus. When NR_CPU count is raised to 4096 the size of cpu_data becomes 3,145,728 bytes. These changes were adopted from the sparc64 (and ia64) code. An additional field was added to cpuinfo_x86 to be a non-ambiguous cpu index. This corresponds to the index into a cpumask_t as well as the per_cpu index. It's used in various places like show_cpuinfo(). cpu_data is defined to be the boot_cpu_data structure for the NON-SMP case.

| | | | | | | | | | | | | | 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.

* [PATCH] fbdev: framebuffer driver for Geode GXDavid Vrabel2006-03-271-0/+262
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.
