2005-06-01[CPUFREQ] ondemand,conservative governor store the idle ticks for all cpusDave Jones2-2/+14
[PATCH] [2/5] ondemand,conservative governor store the idle ticks for all cpus Ondemand, conservative governor did not store prev_cpu_idle_up into prev_cpu_idle_down for other CPUs than the current CPU.

2005-06-01[CPUFREQ] Conservative cpufreq governerDave Jones3-0/+634
A new cpufreq module, based on the ondemand one with my additional patches just posted. This one is more suitable for battery environments where its probably more appealing to have the cpu freq gracefully increase and decrease rather than flip between the min and max freq's. N.B. Bruno Ducrot pointed out that the amd64's "do have unacceptable latency between min and max freq transition, due to the step-by-step requirements (200MHz IIRC)"; so AMD64 users would probably benefit from this too.

2005-06-01[CPUFREQ] fix up comment in cpufreq.hDave Jones1-1/+1
Fix up comment in cpufreq.h stating transition latency should be passed in microseconds -- it was decided long ago to switch to nanoseconds. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Dave Jones <davej@redhat.com>
2005-06-01[CPUFREQ] dual-core powernow-k8Dave Jones2-37/+91
With the release of the dual-core AMD Opterons last week, it's high time that cpufreq supported them. The attached patch applies cleanly to 2.6.12-rc3 and updates powernow-k8 to support the latest Athlon 64 and Opteron processors. Update the driver to version 1.40.0 and provide support for dual-core processors. Signed-off-by: Mark Langsdorf <mark.langsdorf@amd.com> Signed-off-by: Dave Jones <davej@redhat.com>

2005-06-01[CPUFREQ] Recalibrate cpu_khz [2/2]Dave Jones3-2/+25
Some cpufreq drivers (at that time, only powernow-k7) need to recalibrate the cpu_khz at runtime. Signed-off-by: Bruno Ducrot <ducrot@poupinou.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Dave Jones <davej@redhat.com>
2005-06-01[CPUFREQ] Recalibrate cpu_khz [1/2]Dave Jones1-2/+7
We have to recalibrate cpu_khz in order to use the current FID instead the max FID since some BIOS do not put the processor at maximum frequency at POST. Also, some BIOS will change the processor frequency at our back after cpu_khz was calibrate. Finally, this will fix a long standing bug when we do something like this: # rmmod powernow-k7 # modprobe powernow-k7 Signed-off-by: Bruno Ducrot <ducrot@poupinou.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Dave Jones <davej@redhat.com>

2005-06-01[PATCH] flush icache in correct contextRoman Zippel1-0/+6
flush_icache_range() is used in two different situation - in binfmt_elf.c & co for user space mappings and module.c for kernel modules. On m68k flush_icache_range() doesn't know which data to flush, as it has separate address spaces and the pointer argument can be valid in either address space. First I considered splitting flush_icache_range(), but this patch is simpler. Setting the correct context gives flush_icache_range() enough information to flush the correct data.

Add tg3_nvram_lock() and tg3_nvram_unlock() calls around tg3_halt_cpu(). It is possible that the bootcode may be loading code from nvram during this call and stopping the cpu without getting the lock may cause uncompleted nvram data to be left in the nvram data register.

2005-05-30[BRIDGE]: receive path optimizationStephen Hemminger1-1/+1
This improves the bridge local receive path by avoiding going through another softirq. The bridge receive path is already being called from a netif_receive_skb() there is no point in going through another receiveq round trip. Recursion is limited because bridge can never be a port of a bridge so handle_bridge() always returns. Signed-off-by: David S. Miller <davem@davemloft.net>
