Hi Tony, Andrew,
Here are the remaining patches for the PS3 Audio/Video Settings Driver (ps3av)
and the PS3 Virtual Frame Buffer Device Driver (ps3fb) that are not yet in
2.6.23-mm1:
[1] ps3av: Fix black and white stripes
[2] ps3fb: Fix spurious mode change failures
[3] ps3fb: Convert from printk()/DPRINTK() to dev_*()/pr_*()
[4] ps3fb: Do not print warnings on invalid frame numbers
[5] ps3fb: Clean up includes
[6] ps3fb: Make ps3fb_wait_for_vsync() and ps3fb_flip_ctl() static
[7] ps3fb: Fix possible overlap of GPU command buffer and frame buffer
[8] ps3fb: Use fb_info.par properly
[9] ps3fb: Don't keep the borders for non-fullscreen modes in XDR memory
[10] ps3fb: Add virtual screen and panning support
[11] ps3fb: Enhance horizontal panning on firmware 1.90 and up
[12] fb: Move and rename extern declaration for global_mode_option
[13] ps3fb: Default to 480p on DVI-D/HDMI if video=safe
Patches 1-2 are old bug fixes that didn't make it into 2.6.23.
Patches 3-11 were submitted for review last week and received no comments.
Patches 12-13 introduce a safe mode for DVI-D/HDMI displays, to be used by
`kboot'-style boot loaders (i.e. first-stage kernels), as requested by
reviewers of the PS3 video mode autodetection patches (which are in
2.6.23-mm1).
Please apply, thanks!

Fix the black and white stripes issue with WUXGA monitor via HDMI.
It seems that when we use a VESA resolution from boot up, the AV settings
driver could not be initialized correctly.
In that case we need a dummy packet before VESA setting.
[Geert] Refactored to reduce code duplication.

From: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
ps3fb: Add a `mode' parameter to ps3fb_get_res_table(), as in some cases it
should check the full-screen flag of the _new_ video mode instead of the
current video mode.
This bug caused spurious mode change failures when switching between fullscreen
and non-fullscreen modes using fbset, while ps3-video-mode worked fine.

From: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
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()

From: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
ps3fb: Use fb_info.par properly:
o Move mode-specific fields into struct ps3fb_par
o Allocate struct ps3fb_par using framebuffer_alloc()
o Protect access to ps3fb_par in ps3fb_sync() using the console semaphore
(this semaphore is already held when ps3fb_set_par() is called)
o Avoid calling ps3av_set_video_mode() if the actual video mode hasn't
changed

From: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
Don't keep the borders for non-fullscreen modes in XDR memory:
- Extract ps3fb_sync_image()
- Work around the alignment restrictions of L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT
by using an offset with L1GPU_CONTEXT_ATTRIBUTE_DISPLAY_FLIP
- Only copy the visible part of the screen on every vblank
- Always put the real frame buffer at the start of video memory
- Clear fullscreen DDR memory on mode change

From: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
ps3fb: Add virtual screen and panning support:
- The vertical virtual screen size is limited by the amount of memory
reserved for ps3fb,
- The horizontal virtual screen size is limited to the fullscreen width,
- Advertise that we support panning, so fbcon will use it if the virtual
screen is enabled.
Enabling a virtual screen (using `fbset -vyres nnn') can speed up text
console scrolling by a factor of 10-15, depending on the video mode.

From: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
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.

ps3fb: Default to the 480p video mode on DVI-D and HDMI displays if
`video=safe' is passed on the kernel command line.
This is intended to be used by `kboot'-style boot loaders (i.e. first-stage
kernels) for the PS3, to provide a failsafe video mode.

I guess that equals-which-looks-like-it-should-be-equals-equals really
is intended to be an assignment?
I guess. After staring at it for a while. It's a pretty obnoxious way
of coding it, especially in kernel context where such things are unexpected...
