2010-02-27Staging: Octeon: Free transmit SKBs in a timely mannerDavid Daney
If we wait for the once-per-second cleanup to free transmit SKBs, sockets with small transmit buffer sizes might spend most of their time blocked waiting for the cleanup. Normally we do a cleanup for each transmitted packet. We add a watchdog type timer so that we also schedule a timeout for 150uS after a packet is transmitted. The watchdog is reset for each transmitted packet, so for high packet rates, it never expires. At these high rates, the cleanups are done for each packet so the extra watchdog initiated cleanups are neither needed nor triggered.

2010-02-27MIPS: Implement Read Inhibit/eXecute InhibitDavid Daney
The SmartMIPS ASE specifies how Read Inhibit (RI) and eXecute Inhibit (XI) bits in the page tables work. The upper two bits of EntryLo{0,1} are RI and XI when the feature is enabled in the PageGrain register. SmartMIPS only covers 32-bit systems. Cavium Octeon+ extends this to 64-bit systems by continuing to place the RI and XI bits in the top of EntryLo even when EntryLo is 64-bits wide. Because we need to carry the RI and XI bits in the PTE, the layout of the PTE is changed. There is a two instruction overhead in the TLB refill hot path to get the EntryLo bits into the proper position. Also the TLB load exception has to probe the TLB to check if RI or XI caused the exception. Also of note is that the layout of the PTE bits is done at compile and runtime rather than statically. In the 32-bit case this allows for the same number of PFN bits as before the patch as the _PAGE_HUGE is not supported in 32-bit kernels (we have _PAGE_NO_EXEC and _PAGE_NO_READ instead of _PAGE_READ and _PAGE_HUGE). The patch is tested on Cavium Octeon+, but should also work on 32-bit systems with the Smart-MIPS ASE.

2010-02-27MIPS: Use 64-bit stores to c0_entrylo on 64-bit kernels.David Daney
64-bit CPUs have 64-bit c0_entrylo{0,1} registers. We should use the 64-bit dmtc0 instruction to set them. This becomes important if we want to set the RI and XI bits present in some processors.

2010-02-27MIPS: Allow the auxv's elf_platform entry to be set.David Daney
The userspace runtime linker uses the elf_platform to find the libraries optimized for the current CPU archecture variant. First we need to allow it to be set to something other than NULL. Follow-on patches will set some values for specific CPUs. GLIBC already does the right thing. The kernel just needs to supply good data.
