2012-12-13MIPS: PMC-Sierra Yosemite: Remove support.Ralf Baechle1-4/+0
Nobody seems to be interested anymore and upstream also never had an ethernet driver. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2012-07-23MIPS: Add CPU support for Loongson1BKelvin Cheung1-0/+1
Loongson 1B is a 32-bit SoC designed by Institute of Computing Technology (ICT) and the Chinese Academy of Sciences (CAS), which implements the MIPS32 release 2 instruction set. [ralf@linux-mips.org: But which is not strictly a MIPS32 compliant device which also is why it identifies itself with the Legacy Vendor ID in the PrID register. When applying the patch I shoveled some code around to keep things in alphabetical order and avoid forward declarations.] Signed-off-by: Kelvin Cheung <keguang.zhang@gmail.com> Cc: To: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Cc: wuzhangjin@gmail.com Cc: zhzhl555@gmail.com Cc: Kelvin Cheung <keguang.zhang@gmail.com> Patchwork: https://patchwork.linux-mips.org/patch/3976/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2011-06-15MIPS: oprofile: Add callgraph supportDaniel Kalmar1-0/+1
Stack unwinding is done by code examination. For kernelspace, the already existing unwind function is utilized that uses kallsyms to quickly find the beginning of functions. For userspace a new function was added that examines code at and before the pc.

2009-09-17MIPS: Loongson: Add oprofile supportWu Zhangjin1-0/+4
This kernel support is needed by the user-space tool:oprofile to profile linux kernel or applications via loongson2 performance counters. you can enable this driver via CONFIG_OPROFILE = y or m. On Loongson2 there are two performance counters, each one can count 16 events respectively. when anyone of the performance counter overflows, an interrupt will be generated and is routed to the IRQ MIPS_CPU_IRQ_BASE + 6.

2007-10-11[MIPS] Allow hardwiring of the CPU type to a single type for optimization.Ralf Baechle1-1/+1
This saves a few k on systems which only ever ship with a single CPU type. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-06-26[PATCH] oprofile: Fix unnecessary clevernessMarkus Armbruster1-1/+1
nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on model->num_counters (number of performance counters) being less than 10. While this is currently the case, it's too clever by half. Other archs aren't quite as clever: they assume 100. I suggest to normalize them all to 1000.

2006-06-06[MIPS] Fix modpost warning: Rename op_model_xxx to op_model_xxx_ops.Atsushi Nemoto1-4/+4
The modpost uses a whitelist for commonly used suffix on checking the section mismatch. Adding "_ops" suffix to op_modex_xxx get rid of this modpost warning.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+106
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!
