sparc, sparc64: use arch/sparc/include

2008-07-27T21:00:59+00:00

The majority of this patch was created by the following script: *** ASM=arch/sparc/include/asm mkdir -p $ASM git mv include/asm-sparc64/ftrace.h $ASM git rm include/asm-sparc64/* git mv include/asm-sparc/* $ASM sed -ie 's/asm-sparc64/asm/g' $ASM/* sed -ie 's/asm-sparc/asm/g' $ASM/* *** The rest was an update of the top-level Makefile to use sparc for header files when sparc64 is being build. And a small fixlet to pick up the correct unistd.h from sparc64 code. Signed-off-by: Sam Ravnborg

sparc: join the remaining header files

2008-07-18T04:55:51+00:00

With this commit all sparc64 header files are moved to asm-sparc. The remaining files (71 files) were too different to be trivially merged so divide them up in a _32.h and a _64.h file which are both included from the file with no bit size. The following script were used: cd include FILES=`wc -l asm-sparc64/*h | grep -v '^ 1' | cut -b 20-` for FILE in ${FILES}; do echo $FILE: BASE=`echo $FILE | cut -d '.' -f 1` FN32=${BASE}_32.h FN64=${BASE}_64.h GUARD=___ASM_SPARC_`echo $BASE | tr '-' '_' | tr [:lower:] [:upper:]`_H git mv asm-sparc/$FILE asm-sparc/$FN32 git mv asm-sparc64/$FILE asm-sparc/$FN64 echo git mv done printf "#ifndef %s\n" $GUARD > asm-sparc/$FILE printf "#define %s\n" $GUARD >> asm-sparc/$FILE printf "#if defined(__sparc__) && defined(__arch64__)\n" >> asm-sparc/$FILE printf "#include \n" $FN64 >> asm-sparc/$FILE printf "#else\n" >> asm-sparc/$FILE printf "#include \n" $FN32 >> asm-sparc/$FILE printf "#endif\n" >> asm-sparc/$FILE printf "#endif\n" >> asm-sparc/$FILE git add asm-sparc/$FILE echo new file done printf "#include \n" $FILE > asm-sparc64/$FILE git add asm-sparc64/$FILE echo sparc64 file done done The guard contains three '_' to avoid conflict with existing guards. In additing the two Kbuild files are emptied to avoid breaking headers_* targets. We will reintroduce the exported header files when the necessary kbuild changes are merged.

[SPARC64]: Add NUMA support.

2008-04-24T06:32:17+00:00

Currently there is only code to parse NUMA attributes on sun4v/niagara systems, but later on we will add such parsing for older systems. Signed-off-by: David S. Miller

Convert cpu_sibling_map to be a per cpu variable

2007-10-16T16:42:50+00:00

Convert cpu_sibling_map from a static array sized by NR_CPUS to a per_cpu variable. This saves sizeof(cpumask_t) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions.

[SPARC64]: Fix {mc,smt}_capable().

2007-06-05T04:50:05+00:00

It's not just sun4v hypervisor platforms that should return true for this, sun4u with UltraSPARC-IV should return true too. Signed-off-by: David S. Miller

[SPARC64]: Proper multi-core scheduling support.

2007-06-05T04:50:00+00:00

The scheduling domain hierarchy is: all cpus --> cpus that share an instruction cache --> cpus that share an integer execution unit Signed-off-by: David S. Miller

[SPARC64]: Use machine description and OBP properly for cpu probing.

[PATCH] sched: mc/smt power savings sched policy

2006-06-28T00:32:45+00:00

sysfs entries 'sched_mc_power_savings' and 'sched_smt_power_savings' in /sys/devices/system/cpu/ control the MC/SMT power savings policy for the scheduler. Based on the values (1-enable, 0-disable) for these controls, sched groups cpu power will be determined for different domains. When power savings policy is enabled and under light load conditions, scheduler will minimize the physical packages/cpu cores carrying the load and thus conserving power(with a perf impact based on the workload characteristics... see OLS 2005 CMP kernel scheduler paper for more details..)

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

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!
