2007-10-12[MIPS] R1: Fix hazard barriers to make kernels work on R2 also.Ralf Baechle1-1/+53
Tested with Malta; inflates malta_defconfig by 3932 bytes. Ideally there should be additional configuration to allow getting rid of this overhead but that would be too much complexity at this stage of the release cycle. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-09-11[MIPS] Provide empty irq_enable_hazard definition for legacy and R1 cores.Ralf Baechle1-0/+1
Following a strict interpretation the empty definition of irq_enable_hazard has always been a bug - but an intentional one because it didn't bite. This has now changed, for uniprocessor kernels mm/slab.c:do_drain() [...] on_each_cpu(do_drain, cachep, 1, 1); check_irq_on(); [...] may be compiled into a mtc0 c0_status; mfc0 c0_status sequence resulting in a back-to-back hazard.

2007-03-24[MIPS] Fix pipeline hazard.Ralf Baechle1-0/+1
In the the sequence: ei .. mfc0 $x, $status the mfc0 may not see the SR_IE bit set. This was a deliberate bug in the kernel code because we knew this was a safe thing to do on all R2 silicon so far but new silicon is changing this. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-01-24[MIPS] vr41xx: need one more nop with mtc0_tlbw_hazard()Yoichi Yuasa1-1/+1
NEC VR4111 and VR4121 need one more nop with mtc0_tlbw_hazard(). Signed-off-by: Yoichi Yuasa <yoichi_yuasa@tripeaks.co.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-03-18[MIPS] SB1: Fix interrupt disable hazard.Ralf Baechle1-77/+103
The SB1 core has a three cycle interrupt disable hazard but we were wrongly treating it as fully interlocked. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-01-10MIPS: R2: Try to bulletproof instruction_hazard against miss-compilation.Ralf Baechle1-5/+15
Gcc has a tradition of misscompiling the previous construct using the address of a label as argument to inline assembler. Gas otoh has the annoying difference between la and dla which are only usable for 32-bit rsp. 64-bit code, so can't be used without conditional compilation. The alterantive is switching the assembler to 64-bit code which happens to work right even for 32-bit code ... Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+217
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!
