2005-11-13[PATCH] make vesafb build without CONFIG_MTRRJan Beulich
vesafb did not build without CONFIG_MTRR. Cc: "Antonino A. Daplas" <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-11-09[DRIVER MODEL] Convert platform drivers to use struct platform_driverRussell King
This allows us to eliminate the casts in the drivers, and eventually remove the use of the device_driver function pointer methods for platform device drivers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-11-07[PATCH] vesafb: Disable mtrr as the defaultAntonino A. Daplas
vesafb occassionally gets the size wrong when setting the mtrr. When X or DRI attempts to set the mtrr, it will fail due to range overlap significantly affecting their performance. Disable mtrr and let the user explicitly enable it with the mtrr:n option.

2005-11-07[PATCH] vesafb: Fix color palette handlingAntonino A. Daplas
Fix out-of-bounds bug. The pseudopalette has room only for 16 entries, thus, write only the first 16 entries to the pseudopalette. Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

2005-10-18[PATCH] vesafb: Fix display corruption on display blankAntonino A. Daplas
Reported by: Bob Tracy <rct@gherkin.frus.com> "...I've got a Toshiba notebook (730XCDT -- Pentium 150MMX) for which I'm using the Vesa FB driver. When the machine has been idle for some time and the driver attempts to powerdown the display, rather than the display going blank, it goes gray with several strange lines. When I hit the "shift" key or other-wise wake up the display, the old video state is not fully restored..." vesafb recently added a blank method which has only 2 states, powerup and powerdown. The powerdown state is used for all blanking levels, but in his case, powerdown does not work correctly for higher levels of display powersaving. Thus, for intermediate power levels, use software blanking, and use only hardware blanking for an explicit powerdown.

2005-09-09[PATCH] vesafb: Add blanking supportAntonino A. Daplas
Add rudimentary support by manipulating the VGA registers. However, not all vesa modes are VGA compatible, so VGA compatiblity is checked first. Only 2 levels are supported, powerup and powerdown.

To eliminate the warning messages, you can add the option mtrr:2 to add a write-back mtrr for vesafb. Or just use nomtrr option. 1. Fix algorithm for finding the best power of 2 size with mtrr_add(). 2. Add option to choose the mtrr type by extending the mtrr boot option: mtrr:n where n 0 = no mtrr (equivalent to using the nomtrr option) 1 = uncachable 2 = write back 3 = write combining (default) 4 = write through Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-21[PATCH] some vesafb fixesGerd Knorr
Fix the size passed to release_mem_region in an error path. Also adjust the message printed when vesafb cannot load; the comment there already says this must not be fatal, so the message should also not mention the word 'abort' otherwise indicating a problem to worry about in the log.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
