2011-01-18MIPS: Add generic support for multiple machines within a single kernelGabor Juhos
This patch adds a generic solution to support multiple machines based on a given SoC within a single kernel image. It is implemented already for several other architectures but MIPS has no generic support for that yet. [Ralf: This competes with DT but DT is a much more complex solution and this code has been used by OpenWRT for a long time so for now DT is a bad reason to stop the merge but longer term this should be migrated to DT.] Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: linux-mips@linux-mips.org Cc: kaloz@openwrt.org Cc: Luis R.

2009-08-03MIPS: Eleminate filenames from commentsRalf Baechle
They tend to get not updated when files are moved around or copied and lack any obvious use. While at it zap some only too obvious comments and as per Shinya's suggestion, add a copyright header to extable.c.

2009-06-08MIPS: Outline udelay and fix a few issues.Ralf Baechle
Outlining fixes the issue were on certain CPUs such as the R10000 family the delay loop would need an extra cycle if it overlaps a cacheline boundary. The rewrite also fixes build errors with GCC 4.4 which was changed in way incompatible with the kernel's inline assembly. Relying on pure C for computation of the delay value removes the need for explicit. The price we pay is a slight slowdown of the computation - to be fixed on another day.

2007-11-15[MIPS] Fix shadow register support.Ralf Baechle
Shadow register support would not possibly have worked on multicore systems. The support code for it was also depending not on MIPS R2 but VSMP or SMTC kernels even though it makes perfect sense with UP kernels. SR sets are a scarce resource and the expected usage pattern is that users actually hardcode the register set numbers in their code. So fix the allocator by ditching it. Move the remaining CPU probe bits into the generic CPU probe. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-10-11[MIPS] Make facility to convert CPU types to strings generally available.Ralf Baechle

2007-10-11[MIPS] Add support for BCM47XX CPUs.Aurelien Jarno
Note that the BCM4710 does not support the wait instruction, this is not a mistake in the code. It originally comes from the OpenWrt patches.

2006-10-08[MIPS] Show actual CPU information in /proc/cpuinfoKarl-Johan Karlsson
Currently, /proc/cpuinfo contains several copies of the information for whatever processor we happen to be scheduled on. This patch makes it contain the proper information for each CPU, which is particularly useful on mixed R12k/R10k IP27 machines.

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!
