This is based upon Jason's work on xscale. Most of the interrupt handling code is now written in C using an asm stub to call into the C code. spl* now only updates a software mask, and does not update the hardware, this should be much faster. The new code works well on cats, it's untested on netwinder, but should work. The code implements generic soft interrupts. More work is still required to bring the isa interrupt handling code upto scratch currently all isa interrupts are handled at IPL_BIO on the footbridge. This may cause isa interrupts to be handled later than they should be. I plan to fix this in the near future. |
