That's very old; have you tried the latest kernel?
I have one question about cache coherency.
In dma-mapping.h, I found some functions are defined as NU

Hi,
I am using 2.6.14.5 and MPC8349.
I got some DMA problems with PCI devices.
So, I tried to understand the DMA stuff of linux.
I have one question about cache coherency.
In dma-mapping.h, I found some functions are defined as NULL.
For example:
#define dma_cache_inv(_start,_size) do { } whil

Hi Rajasekaran,
Firstly - please don't hijack an existing thread when asking a new, completely
unrelated question. Start a new thread with a relevant title.

HI,
I would like to port a linux kernel to a 8051 Microcontroller
C8051F120(128kB flash memory 8KB Ram ).
Is this really possible?
What book would help me in porting a linux kernel to a modest
microcontroller such as 8051?
Any help would be greatly appreciated
Thanks in Advance
K.Ra
