Hi, I just figured out that I need to use m8xx_cpm_hostalloc() to allocate memory for "buffer" that needs to be attached to the "Buffer Descriptor" of an MPC8xx CPM peripheral (like IIC, SPI, SCC etc). Instead, if I try to use kmalloc() or a static memory allocation, my driver isn't working.
1) Can somebody throw some light on what exactly is the difference between m8xx_cpm_hostalloc() and kmalloc(). 2) Why is the difference important in ppc linux ? Thanks -- Rupesh S ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
