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.

* [patch 11/13] ps3fb: Enhance horizontal panning on firmware 1.90 and up
From: Geert Uytterhoeven @ 2007-10-12 14:51 UTC (permalink / raw)

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.

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.

* [patch 09/13] ps3fb: Dont keep the borders for non-fullscreen modes in XDR memory

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

* [patch 08/13] ps3fb: Use fb_info.par properly

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

* [patch 07/13] ps3fb: Fix possible overlap of GPU command buffer and frame buffer
From: Geert Uytterhoeven @ 2007-10-12 14:50 UTC (permalink / raw)

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: 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: Masashi Kimoto <Masashi_Kimoto@hq.scei.sony.co.jp>
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.

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!

I'll pull the one in the URL soon, yes. This patch, and the RGMII

I believe we should really have a generic way to probe ATA
ports as long as they are compatible to the standard register
set, and use a generic of-ata driver for that. The two
questions arising there are:
1. Should there be a new device-type for ATA? Alternatively
we would only look at the "compatible" property, maybe
looking for a generic "ata" name.
2. How do we make sure the of-ata driver and the specific
(e.g. sata_fsl) driver don't fight over the same devices?
Would it be enough to reject all known specific devices
in of_ata_probe?

This should be fine, as cd->sfis is allocated in host memory using a
_coherent allocator and the SATA-2 controller is
DMA'ing the D2H FIS into it.

If cd->sfis points at memory over the PCI bus (eg mmio or memory on the
controller card) then you need to use ioread/_io type functions. If
cd->sfis points into host memory where the FIS is delivered by DMA from
the card you will be fine if it was allocated with an _coherent
allocator

Some of my comments here are similar to those for the ata driver,
so I won't be as verbose here

of_iomap?
Also, shouldn't there be a matching iounmap?

I suppose the reason why you can't use an of_platform_device here is that
the serdes node is a child of the actual device that is using the serdes
interface, right?
Could you perhaps call fsl_serdes_init from all the drivers that can have
a serdes attachment, and pass the parent device into the setup function?

These can all be moved to the source file so you can kill the

Thanks for the clarification. So the code here is ok, that we use

Hmm, I think we should redefine of_iomap to do the right thing
for you. currently, it is the combination of of_address_to_resource
and ioremap, which you do as well, so your code can be simplified
to do that. However, ioremap is meant to be used with readl/writel
or in_le32/out_le32 and similar functions, not with ioread32/iowrite32
which you are using.
I had planned to do a patch to get that right for some time so
you can use of_iomap with ioread in all cases, but I guess you
should start using of_iomap even now.

Once of_iomap start using devres, we would no longer need to iounmap here.

The header file is entirely pointless, since all definitions in here
are only used in a single file. Please merge the header into the

In particular, get rid of the forward declarations for static functions.
All functions in a simple driver should be ordered in a way that you
always reference only code that was previously defined. This helps
avoid accidental recursions and makes it easier to review.

If cd->sfis points at memory over the PCI bus (eg mmio or memory on the
controller card) then you need to use ioread/_io type functions. If
cd->sfis points into host memory where the FIS is delivered by DMA from
the card you will be fine if it was allocated with an _coherent allocator

* [PATCH v2] drivers/ata: add support to Freescale 3.0Gbps SATA Controller
From: Li Yang @ 2007-10-12 13:47 UTC (permalink / raw)
To: jgarzik, linux-ide; +Cc: linuxppc-dev, Li Yang, Ashish Kalra
From: Ashish Kalra <ashish.kalra@freescale.com>
This patch adds support for Freescale 3.0Gbps SATA Controller supporting
Native Command Queueing(NCQ), device hotplug, and ATAPI. This controller
can be found on MPC8315 and MPC8378.

Clean up all the leftover of CONFIG_SATA_FSL_FPGA_PCI.
So far there is no comment on the SATA device node definition. I'd assume
that we can close on it.
