Turns out b868868ae0f7272228c95cc760338ffe35bb739d wasn't quite right. When called for a page that isn't marked dirty it would artificially create an alias instead of doing the obvious thing and access the page via KSEG0. The same issue also exists in copy_to_user_page and copy_from_user_page which was causing the machine to die under rare circumstances for example when running ps if the BUG_ON() assertion added by the earlier fix was getting triggered.

2007-10-16tgafb: remove a redundant non-mono test in mono imageblitMaciej W. Rozycki
There is a test in tgafb_mono_imageblit() for a colour image with a fall-back to cfb_imageblit(). The test is not necessary as the only caller, which is tgafb_imageblit(), checks it too and only invokes this function for monochrome images. It looks like a left-over from before some changes to tgafb_imageblit(). Signed-off-by: Maciej W.

2007-10-16tgafb: fix an out-of-range shift in mono imageblitMaciej W. Rozycki
The pixel mask calculation in tgafb_mono_imageblit() uses a variable left-shift on a 32-bit data type by up to 32. Shifting by the width of a data type or more produces an unpredictable result according to the C standard. Rather than widening the data type this fix makes sure the count is between 0 and 31. The reason is not to penalise 32-bit platforms with operation on a "long long" type for a marginal case that is meant not to happen (blitting an image of a zero width). The reason it has escaped for so long is the Alpha, being purely 64-bit, :-) does not mask the shift out to 32 bits. This is a valid implementation -- producing the correct result certainly falls within "unpredictable behaviour". It does trigger on MIPS though and it is the recent merge of the TC support which only enabled the driver for use on anything other than the Alpha. For MIPS when the width is 32 the mask ends up being 0 rather than 0xffffffff as it should be and the frame buffer is not updated. Signed-off-by: Maciej W.

2007-10-16fbcon: delay the start of the cursor timer until a con_switch()Antonino Daplas
As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular cursor can still be seen blinking in the upper left part of the screen. It is fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE, KD_TEXT) call done by something in userspace, perhaps by X itself, while the tty is still in graphics mode. And when the tty is in KD_TEXT mode, the cursor timer is restarted. Although this is a userspace problem, we can work around it by delaying the restart of the cursor timer until an fbcon_switch() is called. In other words, the cursor timer will not be restarted even if a KD_TEXT mode switch is requested.

2007-10-16ps3fb: enhance horizontal panning on firmware 1.90 and upGeert Uytterhoeven
ps3fb: Enhance horizontal panning on firmware 1.90 and up: - On firmware 1.90 and up, L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT supports copying rectangles from XDR to DDR memory with different source and destination line lengths. Hence larger horizontal virtual resolutions can be supported (up to 16368 pixels). - As the actual frame buffer memory layout no longer matches the entries in ps3fb_res[], create fake struct ps3fb_ioctl_res data for the PS3FB_IOCTL_SCREENINFO ioctl, so user space applications that depend on it keep on working.

2007-10-16ps3fb: fix possible overlap of GPU command buffer and frame bufferGeert Uytterhoeven
ps3fb: In the case of non-fullscreen video modes, there was a partial overlap of the GPU command buffer and the frame buffer. Fix and cleanup various issues with overlap and alignment: - Move the GPU command buffer from the beginning to the end of video memory - Exclude the GPU command buffer from the actual frame buffer memory - Align the start of the virtual frame buffer to PAGE_SIZE instead of to 64 KiB, and don't waste memory if it's already aligned (for fullscreen modes) - Take into account the alignment when checking memory requirements and maximum number of frames - Make sure fb_fix_screeninfo.smem_start always points to the virtual frame buffer start, so we don't have to compensate for that in ps3fb_mmap() Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Cc: "Antonino A.
