* PM/gxfb: add hook to PM console layer that allows disabling of suspend VT switchAndres Salomon2008-04-28
| | | | | | | | | | | | | | | | | | | | | | 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..)

* gxfb: add power management functionalityAndres Salomon2008-04-28
| | | | | | | | | | | | | | | | | | | This adds the ability to suspend/resume the gxfb driver, which includes: - The addition of a Graphics Processor register table in gxfb.h, and associated GP handling. - Register and palette saving code; registers are stored in gxfb_par. A few MSR values are saved as well. - gx_powerup and gx_powerdown functions which restore/save registers and enable/disable graphic engines. - gxfb_suspend/gxfb_resume Originally based on a patch by Jordan Crouse.

* gxfb: stop sharing code with gx1fbAndres Salomon2008-04-28
| | | | | | | | | | | | | | | | | | 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: clean up register definitionsAndres Salomon2008-04-28
| | | | | | | | | | | | | | | | | | | | 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.

We also drop a no-op readl() from gx_set_mode. Other than that, there should be no functionality change.

* gxfb: replace FBSIZE config option with a module parameterAndres Salomon2008-04-28
| | | | | | | | | | | | | | | 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.

* gxfb: set the right registers to tweak the sync polarityJordan Crouse2008-04-28
| | | | | | | | | | | | | | | 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.

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.

* fbdev: make the best-fit section of fb_find_mode return the closest matching ↵Michal Januszewski2008-04-28
| | | | | | | | | | | | | | | | | | | | mode Currently, if a perfect match in terms of resolution is not found, fb_find_mode() only looks for a best-fit mode among modes with a higher resolution than the one requested. Thus, if the user requests a resolution higher than the largest supported one, they are dropped to the default mode (usually a low resolution one). Change this behaviour so that all valid video modes are considered when looking for a best-fit mode, while still preferring modes with a higher resolution.

This is useful for devices that aren't always present, such as GPIOs on hotplugged devices rather than mainboards. (This behavior was previously specified but not implemented.) To avoid using any numbers that may have been explicitly assigned but not yet registered, this dynamic allocation assigns GPIO numbers from the biggest number on down, instead of from the smallest on up.

The existing mechanism (gpiochip_remove failure) doesn't address that, since rmmod can no longer be made to fail by having the cleanup code report errors. Module usecounts are the solution. Assuming standard "initialize struct to zero" policies, this change won't affect SOC platform drivers. However, drivers for external chips (on I2C and SPI busses) should be updated if they can be built as modules.

* quota: quota core changes for quotaon on remountJan Kara2008-04-28
| | | | | | | | | | | | | Currently, we just turn quotas off on remount of filesystem to read-only state. The patch below adds necessary framework so that we can turn quotas off on remount RO but we are able to automatically reenable them again when filesystem is remounted to RW state. All we need to do is to keep references to inodes of quota files when remounting RO and using these references to reenable quotas when remounting RW.
