2008-07-12fbdev: bugfix for multiprocess defioJaya Kumar
This patch is a bugfix for how defio handles multiple processes manipulating the same framebuffer. Thanks to Bernard Blackham for identifying this bug. It occurs when two applications mmap the same framebuffer and concurrently write to the same page. Normally, this doesn't occur since only a single process mmaps the framebuffer. The symptom of the bug is that the mapping applications will hang. The cause is that defio incorrectly tries to add the same page twice to the pagelist. The solution I have is to walk the pagelist and check for a duplicate before adding. Since I needed to walk the pagelist, I now also keep the pagelist in sorted order.

This patch fixes several issues: Use the right openprom device name so the driver is actually loaded. Fix a crash due to unitialized info->pseudo_palette. Put the framebuffer in the proper mode for software rendering. checkpatch cleanups. Hardware acceleration was removed when the driver was rewritten for the new framebuffer API in 2003. Software rendering requires a different framebuffer access mode but that wasn't changed. The driver now works again but is slow. The proper fix is to reintroduce hardware acceleration.

2008-05-27xen pvfb: Dynamic mode support (screen resizing)Markus Armbruster
The pvfb backend indicates dynamic mode support by creating node feature_resize with a non-zero value in its xenstore directory. xen-fbfront sends a resize notification event on mode change. Fully backwards compatible both ways. Framebuffer size and initial resolution can be controlled through kernel parameter xen_fbfront.video. The backend enforces a separate size limit, which it advertises in node videoram in its xenstore directory. xen-kbdfront gets the maximum screen resolution from nodes width and height in the backend's xenstore directory instead of hardcoding it. Additional goodie: support for larger framebuffers (512M on a 64-bit system with 4K pages). Changing the number of bits per pixels dynamically is not supported, yet.

2008-05-27xen: Enable console tty by default in domU if it's not a dummyMarkus Armbruster
Without console= arguments on the kernel command line, the first console to register becomes enabled and the preferred console (the one behind /dev/console). This is normally tty (assuming CONFIG_VT_CONSOLE is enabled, which it commonly is). This is okay as long tty is a useful console. But unless we have the PV framebuffer, and it is enabled for this domain, tty0 in domU is merely a dummy. In that case, we want the preferred console to be the Xen console hvc0, and we want it without having to fiddle with the kernel command line. Commit b8c2d3dfbc117dff26058fbac316b8acfc2cb5f7 did that for us. Since we now have the PV framebuffer, we want to enable and prefer tty again, but only when PVFB is enabled. But even then we still want to enable the Xen console as well. Problem: when tty registers, we can't yet know whether the PVFB is enabled. By the time we can know (xenstore is up), the console setup game is over. Solution: enable console tty by default, but keep hvc as the preferred console. Change the preferred console to tty when PVFB probes successfully, unless we've been given console kernel parameters.

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.

Another addendum to commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b ("vt: fix background color on line feed"). fbcon still was not doing the right thing (read: continued to do old behavior). fbcon_clear() seems to clear the new line (e.g. where your new prompt appears after doing echo -en "\e[42mfoo\n"), while scr_memsetw clears the previous one only (where "foo" appears). So just temporarily set the video_erase_char to the scrl_erase_char so that fbcon_clear does the right thing.

Addendum to commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b ("vt: fix background color on line feed"). vc->vc_scrl_erase_char was not updated when fbcon switches between 256- and 512-glyph fonts.

2008-05-13fbdev: do not let CONFIG_FB_DEFERRED_IO default to yGeert Uytterhoeven
CONFIG_FB_DEFERRED_IO can not be turned off, while it's already selected automatically by the drivers that need it. Although it's nice to have more compile-coverage, not being able to disable a rarely used feature is annoying.

2008-05-13atmel_lcdfb: fix pixclock divider calculationNicolas Ferre
Fix divider calculation and allow CLKVAL = 0 (divisor 2) It was not possible to get the clock value 0 (divisor 2) because the test "<=0" force the BYPASS bit to be activated instead.

2008-05-13drivers/video/pnx4008: eliminate double freeJulia Lawall
The function framebuffer_release just calls kfree, so calling kfree subsequently on the same argument represents a double free. The comments with the definition of framebuffer_release in drivers/video/fbsysfs.c suggest that a more elaborate definition of this function is planned, such that the splitting up of framebuffer_release and kfree as done in the second instance might someday make sense, but it does not make sense now. This was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E; @@ * kfree(E); ... * framebuffer_release(E); @@ expression E; @@ * framebuffer_release(E); ... * kfree(E); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Vitaly Wool <vitalywool@gmail.com> Cc: Krzysztof Helt <krzysztof.h1@wp.pl> Cc: Grigory Tolstolytkin <gtolstolytkin@ru.mvista.com> Cc: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
