For non-smp kernels the call to update_process_times is done in the do_timer function. It is more consistent with smp kernels to move this call to the architecture file which calls do_timer. Signed-off-by:

These had been officially deprecated since Rusty's module rewrite, but never got the __deprecated marker. The only remaining users are drm and mtd, so we'll get some warnings for common builds. But maybe that's the only way to get the drm people to fix the mess :) Signed-off-by:

Relatively minor add-on (not necessarily tied to it or required to be taken or a fix for any bug). Since cond_resched() is using PREEMPT_ACTIVE now, it may be useful to update the open-coded instance of cond_resched() to use the generic call. Also, it should probably be __sched so the caller shows up in wchan. Signed-off-by:

In arch/i386/kernel/acpi/boot.c, platform GSI does not propagate back from mp_register_gsi() to a calling routine which results in IRQ to be set for wrong GSI. This causes most of the PCI slots on the first PCI module to fail. This patch fixes the problem by returning new GSI back to acpi_register_gsi(). Signed-off-by:

Having recently repaired autofs' ability to recognise updates to maps dynamically I found I needed to reintroduce the directory inode lookup method (I broke the update recognition several versions ago, oops). This patch does this and applies cleanly against 2.6.9-rc1-mm4. As far as I can tell from testing it doesn't introduce any backward incompatibilities. Signed-off-by:

The pid_max sysctl doesn't enforce PID_MAX_LIMIT or sane lower bounds. RESERVED_PIDS + 1 is the minimum pid_max that won't break alloc_pidmap(), and PID_MAX_LIMIT may not be aligned to 8*PAGE_SIZE boundaries for unusual values of PAGE_SIZE, so this also rounds up PID_MAX_LIMIT to it. Signed-off-by:

For several months I'm receiving complaints from matroxfb users that v4lctl suddenly stops working for them on kernel upgrade. Problem is that VIDIOC_S_CTRL was renumbered, but all distros still use old VIDIOC_S_CTRL value (f.e. even xawtv-3.94 in Debian unstable still uses old VIDIOC_S_CTRL definition). So let's add this old VIDIOC_S_CTRL value (now named VIDIOC_S_CTRL_OLD) to matroxfb's v4l handling. Signed-off-by:

This patch cleans up some old cruft in the manipulation of the LVDS interface registers and fixes the blanking code to work with various DVI flat panels. Since this is all very sensitive stuff, I'm posting the patch here for testing before submitting it upstream, though Andrew is welcome to put it in -mm. It also fix some problems with getting the right PLL setup on recent Mac laptops, replacing the old hard coded list of values with cleaner code that "probes" the PLL setup done by the firmware.

This small change does: (1) Properly document 'outputs' option. (2) Properly use accelerated characters drawing. fbcon used depth == 0 for character painting long ago, but it is fixed for several months. (3) Provide correct hints for fbcon about matroxfb/matroxfb_crtc2 hardware capabilities. Signed-off-by: -

One of the PowerPC developers, Kostas Georgiou, pointed out to me discussion back from 2001 that they would prefer little endian mode as majority of users runs XF4.x and not Xpmac. And apparently nobody runs Xpmac now, so we can safely remove big-endian mode from matroxfb completely. So let's simplify matroxfb a bit: Accelerator and ILOAD fifo is now always in little endian mode. This is what XFree does. Due to this change all #ifdefs based on endianness was removed from driver - except one which selects framebuffer endinaness (but there is no code in matroxfb which writes to framebuffer directly). It seems that while I was not looking m68k got ioremap, and all architectures now offer ioremap and ioremap_nocache. Let's kill code which mapped ioremap_nocache to ioremap, and ioremap to bus_to_virt for architectures which did not provide them. And this also fixes small typo - M_C2CTL should be 0x3C10 and not 0x3E10. Apparently Matrox notes about need to program this register during initialization are not so important... Signed-off-by:

From: Gerd Knorr <kraxel@bytesex.org>: "IMHO the the only sane thing is to have two options for total + remapped memory as well. Otherwise we'll end up changing that back and forth like it happened for the size calculation stuff for quite some time ...

EDID_INFO is encroaching on the space meant for E820 map in zero-page. This will result in E820 map corruption on any system that has more=20 than 18 E820 entries and CONFIG_VIDEO_SELECT.

fbcon doesn't set a unimap at boot time, so special characters come out wrongly. This is the code sequence in take_over_console(). newcon->startup() oldcon->deinit() newcon->init() The previous console driver (ie, vgacon), via its deinit method, may release the unimap allocated by fbcon in fbcon_startup. This is the reason why calling con_set_default_unimap() in fbcon_init() works, but not in fbcon_startup(). Check if the default display has an allocated unimap, and if it has none, call con_set_default_unimap(). And if the target display has no allocated unimap, then call con_copy_unimap(), where the source unimap is from the default display. Signed-off-by:

From: Egbert Eich <eich@suse.de> I would like to utilize kernel ioctls to save/restore console fonts in VGA text mode when running X. So far the Xserver takes care of this however there more and more problems with this: 1. On some platforms (IA64) we need to POST the BIOS before we even have a chance to access the hardware ourselves. This POSTing will usually undo any changes to the graphics hardware that the kernel may have done. 2. More and more drivers fully rely on BIOS support however the BIOS functions which could be used to save/restore register settings may be broken so the only way of mode save/restore is getting/setting the BIOS mode ID. I've hacked up some code for X however I ran into two problems: 1. con_font_get() in linux/drivers/char/vt.c seems to be broken as the font parameters (height, width, charcount) are never reported back. Therefore this function seems to be pretty useless. The fix is simple (please see below). 2. fb consoles seem to allow to install fonts per vt so that the user can have a different font on every console. The text console driver doesn't support this: the font is downloaded to the video card and will be used for all systems. Still the vga_con driver stores the font parameters per console with the effect that setting a font with different parameters on one console will result in the wron values when this font information is read back from another console. Appearantly this broken feature has been introduced in 2.6 as in the 2.4 kernel the vga_con font information is stored in one single global variable. The IA64 platform at least still heavily relies on the VGA text console. To be able to fix some VT switching issues with X on this platform I need these two issues resolved. Signed-off-by: -

When Antonino A. Daplas posted his "fbdev: Initialize i810fb after agpgart" patch he said that the ugly agp initialization hack for intel agp shouldn't be needed but that he couldn't test it. I have tested the framebuffer updates and additionally removed the initialization hack and it does indeed work. Signed-off-by:

Hopefully, this patch fixes one last major regression for one particular driver, namely matroxfb. This drier has 2 versions, one for the kernel and another as a '2.4 backport' patch. This patch adds a tileblitting extension to fbcon. This extension, in summary, is basically a forward-port of the 2.4 fbdev/fbcon framework to 2.6 but without the fbcon dependency. Tile blitting is similar to bitblit, except that the basic unit is a tile (a bitmap of x-by-y dimensions). The display, instead of being described in terms of pixels and scanlines, are described as a region further subdivided into rectangular sections. In fbcon parlance, a tile is a character. Besides a possible fix for matroxfb, tileblitting can be advantageous for hardware that supports some kind of fontcaching mechanism. Also, in the unlikely chance that the console begins supporting multicolored fonts, tileblitting is probably more optimal than bitblitting because bitblitting will need to push more data through the bus. To enable support for this extension, a driver needs to: - enable CONFIG_FB_TILEBLITTING - set FBINFO_MISC_TILEBLITTING in info->flags - set the required function pointers in struct fb_tileops. The required operations are: - void (*fb_settile)(struct fb_info *info, struct fb_tilemap *map); tells driver about the tile characteristics (dimensions, bitdepth) and about the tilemap which is an array of bitmaps: display->fontdata - void (*fb_tilecopy)(struct fb_info *info, struct fb_tilearea *area); move a rectangular section of tiles (bmove) - void (*fb_tilefill)(struct fb_info *info, struct fb_tilerect *rect); fill a rectangular section with a tile (clear) - void (*fb_tileblit)(struct fb_info *info, struct fb_tileblit *blit); copy an array of tiles to a rectangular section (putcs) - void (*fb_tilecursor)(struct fb_info *info, struct fb_tilecursor *cursor); cursor function Changes: Addition of this extension necessitates cleanup of fbcon.c. The basic drawing functions in fbcon are bmove, clear, putcs and cursor (the fbcon_* set). The fbcon_* set are just wrappers to accel_* set. However, usage is not consistent, some functions call the fbcon_* set, others call the accel_* set. With this patch, a new fbcon-specific structure (struct fbcon_ops) is created. Depending on the setting of the hardware, this struct contains pointers to either the tileblitting set or the bitblitting set (formerly the accel_* set). The tileblitting set is new in this patch. The vast majority of functions in fbcon will need to only call the fbcon_* set. In turn, it calls functions in struct fbcon_ops. Knowledge of the blitting type is not required. The accel_* set is renamed to bit_* and is moved into a separate file, bitblit.c. The tile blitting set is in tileblit.c. In my case at least, the cleanup did produce an unexpected but beneficial side effect, a little more speedup. Not much, < 5%. Petr, if you have comments, suggestions, or you think this is a bad idea, let me know. Signed-off-by: -

Swsusp turns off the display when a power-management-enabled framebuffer driver is used. According to Nigel Cunningham <ncunningham@linuxmail.org>, the fix may involve the following: "...I thought the best approach would be to use device classes to find the struct dev for the frame buffer driver, and then use the same code I use for storage devices to avoid suspending the frame buffer until later..." Changes: - pass info->device to class_simple_device_add() - add struct device *device to struct fb_info - store struct device in framebuffer_alloc() - for drivers not using framebuffer_alloc(), store the struct during initalization - port i810fb and rivafb to use framebuffer_alloc() Signed-off-by:

This patch fixes the 'fbcon=map:<option>" of fbcon. (This option has been present since 2.4, but got broken in 2.6). This particular option tells fbcon what framebuffer device gets mapped to what console. Syntax is: fbcon=map:abcd... where a, b, c, d,... are framebuffer numbers as it would appear in /proc/fb. Given only 2 valid fbdevs, 0 and 1, if fbcon=map:0110, then: tty1 = fb0 tty2 = fb1 tty3 = fb1 tty4 = fb0 (sequence repeats for the rest of the consoles) If an invalid framebuffer is used, then the console will be mapped to the first user-chosen framebuffer. Ie: fbcon=map:102 tty1 = fb1 tty2 = fb0 tty3 = fb1 <
