| * [MIPS] PNX8550: Cleanup proc code.Robert P. J. Day2007-07-101-13/+17
| | | | | | | | | | | | | | | | | | Here's a slightly cleaner way of creating the /proc structure for the pnx8850. mostly, it creates a directory with default mode 555, since the one you're creating is mode 444, which is somewhat unusual for a directory under /proc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently a number of unaligned instructions is counted but not used. Add /debug/mips/unaligned_instructions file to show the value. And add /debug/mips/unaligned_action to control behavior upon an unaligned access.

(background: TX49XX SoCs include PCI NIC (TC35815 compatible) connected via its internal PCI bus, but the NIC's PROM interface is not connected to SEEPROM.

| * [MIPS] DECstation: Optimised early printk()Maciej W. Rozycki2007-07-103-7/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an optimised implementation of early printk() for the DECstation. After the recent conversion to a MIPS-specific generic routine using a character-by-character output the performance dropped significantly. This change reverts to the previous speed -- even at 9600 bps of the serial console the difference is visible with a naked eye; I presume for a framebuffer it is even worse (it may depend on exactly which one is used though). Additionally the change includes a fix for a problem that the old implementation had -- the format used would not actually limit the length of the string output. This new implementation uses a local buffer to deal with it -- even with this additional copying it is much faster than the generic function. Plus this driver is registered much earlier than the generic one, allowing one to see critical messages, such as one about an incorrect CPU setting used, that are produced beforehand. :-) Signed-off-by: Maciej W.
