Re: [Qemu-devel] Sparc system patch 12

[Blue Swirl]

Hi,

I looked at the data sheets of the both chips and your driver. Good news is 
that all the 16-bit data structures used in Sparc are implemented in your 
driver. Bad news is that the endianness bit (CSR3 BSWP) is not implemented 
in either driver, and both assume different endianness.

Then there is Sparc-specific I/O MMU, which translates device virtual 
addresses issued by the DMA controller to physical ones. It needs to fix all 
memory accesses, but this is easy.
