2008-05-14fix "lxfb: extend PLL table to support dotclocks below 25 MHz"Jens Rottmann1-22/+0
The following patch caused a regression with OLPC panels: commit 3888d4639e78802c4ec1086127124e890461b9e4 lxfb: extend PLL table to support dotclocks below 25 MHz Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25 MHz. These are needed for small LCDs (e.g. 320x240). Also inserts some intermediate steps between pre-existing frequencies. The problem was the insertion of intermediate steps into the frequency table; they would cause the wrong frequency to be matched. This patch drops those intermediate frequencies while keeping the sub-25MHz frequencies.

2008-04-28OLPC: gxfb/lxfb: add DCON panel modes to framebuffer driversAndres Salomon2-7/+67
Since there's no way to autodetect panel modes, we're forced to hardcode them in the driver and add a big fat #ifdef. The OLPC DCON needs a specific mode line (at 1200x900). This adds it to both gxfb and lxfb. (Jordan said: We could probably detect the panel mode, but there isn't any reason to since the panel timings are well known and won't change. While OFW detection would be good computer science fu, it would be a wasted effort since its so easy to hard code them into the table.)

2008-04-28PM/gxfb: add hook to PM console layer that allows disabling of suspend VT switchAndres Salomon1-0/+7
Prior to suspend, we allocate and switch to a new VT; after suspend, we switch back to the original VT. This can be slow, and is completely unnecessary if the framebuffer we're using can restore video properly. This adds a hook that allows drivers to select whether or not to do this vt switch, and changes the gxfb driver to call this hook. It also adds a module param to gxfb to allow controlling of the vt switch (defaulting to no switch). (Note: I'm not convinced that console_sem is the best way to protect this, but we should probably have some form of locking..)

We want to stop sharing stuff with gx1fb; it makes little sense.

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.

2007-10-19x86: convert cpuinfo_x86 array to a per_cpu arrayMike Travis1-1/+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.

2006-12-08[PATCH] gxfb: Fixups for the AMD Geode GX framebuffer driverJordan Crouse6-1/+65
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.

2006-12-07[PATCH] Trivial cleanup in the PCI IDs for the CS5535Jordan Crouse1-1/+1
Rename a poorly worded PCI ID for the Geode GX and CS5535 companion chips. The graphics processor and host bridge actually live in the northbridge on the integrated processor, not in the companion chip.

2006-07-10[PATCH] vt: Remove VT-specific declarations and definitions from tty.hJon Smirl2-2/+0
MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h allows all of the framebuffer and VT console drivers to remove their dependency on tty.h.

2006-06-26[PATCH] Detaching fbcon: remove calls to pci_disable_device()Antonino A. Daplas2-6/+0
Detaching fbcon allows individual drivers to be unloaded. However several drivers call pci_disable_device() upon exit. This function will disable the BAR's which will kill VGA text mode and/or affect X/DRM. To prevent this, remove calls to pci_disable_device() from several drivers.

2006-03-27[PATCH] fbdev: framebuffer driver for Geode GXDavid Vrabel7-2/+1003
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.

2006-01-14[PATCH] gx1fb: (try to) play nicer with various BIOSesDavid Vrabel1-7/+4
Seems that the CS5530A chip used in Geode GX1 systems has some crazy feature that causes SMI traps when accessing the PCI configuration space of the video device. Various GX1 BIOSes seem to use this 'feature' to hide the real BARs of the device. This patch disables these traps (in an early PCI fixup) so that Linux sees the real, physical BARs and not the virtual ones provided by the BIOS. This should allow the GX1 framebuffer driver to work on more systems that have different BIOSes as the driver no longer guesses at what the virtual BARs mean. I'm not entirely sure it the correct solution as I can neither test regular VGA console nor the X's 'cyrix' video driver so there might be some breakage there -- probably best to get some more testers before applying it.
