Thanks for all the suggestions and Comments!
In the system, the total memory size is less than 4GB. I want to know how to
map the 3GB pci address to the kernel ,
and how can my driver access all the pci device. Usually we have only 1GB
kernel address, minus the 896MB
for memory map, we can onl

Commit d015fe995 'powerpc/cell/axon-msi: Retry on missing interrupt'
has turned a rare failure to kexec on QS22 into a reproducible
error, which we have now analysed.
The problem is that after a kexec, the MSIC hardware still points
into the middle of the old ring buffer. We set up the ring buffer

Hi!
Reading of "powerbook VT garbled between rc7 and rc8" by
Johannes Berg reminded me of my own graphics problem with the X.org radeon
driver when connected to a TFT panel using the DVI connector.
The symtom: after initial X video initialization the screen flickers red. This

I am using the ppc460ex as an endpoint and I see that the mentioned
function setups a 32Mb
window at address 0 in sdram. what i want is some memory that the host
can read/write to.
But the 32Mb that are already mapped at the bottom of ram, so it would
not be good do writes
to those addresses. Am

Hm. Then you don't need a chip-select, and SPI driver must understand
this case. When SPI controller has no "gpios" pro

This patch adds a dummy GPIO driver, which is useful for SPI devices
that do not have a physical chip select.

The SPI subsystem requires a chip-select for each connected slave
device. I have a custom board with an Atmel "co-processor". This part
is reprogramme

Hi,
After upgrading to -rc8 yesterday my powerbook started up today with the
screen totally garbled, only occasionally was a word readable. I also
tried adding radeonfb=accel_cexp to the command line but that changed
nothing. Also, once I was in X, it seemingly worked fine, but then I
