2006-11-30[MIPS] Don't print presence of WAIT instruction on bootup.Ralf Baechle
Not useful and quite a big of noise on bootup of large systems. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-10-09[MIPS] Fix RM9000 wait instruction detection.Ralf Baechle
Only revisions < 4.0 don't have a functional wait instruction. From Thomas Koeller (Thomas.Koeller@baslerweb.com). Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-09-27[MIPS] Reduce race between cpu_wait() and need_resched() checkingAtsushi Nemoto
If a thread became runnable between need_resched() and the WAIT instruction, switching to the thread will delay until a next interrupt. Some CPUs can execute the WAIT instruction with interrupt disabled, so we can get rid of this race on them (at least UP case). Original Patch by Atsushi with fixing up for MIPS Technology's cores by Ralf based on feedback from the RTL designers.

2006-07-13[MIPS] Save 2k text size in cpu-probeThiemo Seufer

2006-06-06[MIPS] SB1: Only pass1 FPUs are broken beyond recovery.Ralf Baechle
The wrong revision number in the check was forcing a fallback to FPU emulation for all SB1 cores in 2.6. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-06-01[MIPS] Fix detection and handling of the 74K processor.Chris Dearman
Nothing exciting; Linux just didn't know it yet so this is most adding a value to a case statement. Signed-off-by: Chris Dearman <chris@mips.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2005-10-29No point in checking cpu_has_tlb before we've computed the CPU options.Ralf Baechle
So for now we just unconditionally set the option - Linux wouldn't work without a TLB anyway. Setting MIPS_CPU_4KTLB was missing for Alchemy and Sandcraft, add that back. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
