[PATCH V2 0/6] cpufreq: cleanups and reorganization

by Viresh Kumar

Hi Rafael, This cleans up cpufreq core and few platform drivers a bit. Its mostly around cleaning up the usage of cpufreq_frequency_table_target(), which will be optimized in a separate series. This is just preparatory cleanup for that. V1->V2: - Dropped one powernv patch which wasn't really required. - Dropped one more patch as its already applied by the ARM mach maintainer. - Added Reviewed-by in the first patch - Just rebased otherwise, no other changes. Viresh Kumar (6): cpufreq: s3c24xx: Remove useless checks cpufreq: Remove cpufreq_frequency_get_table() cpufreq: ondemand: Don't keep a copy of freq_table pointer cpufreq: Drop freq-table param to cpufreq_frequency_table_target() cpufreq: Drop 'freq_table' argument of __target_index() cpufreq: Return index from cpufreq_frequency_table_target() Documentation/cpu-freq/cpu-drivers.txt | 8 ++--- drivers/cpufreq/amd_freq_sensitivity.c | 10 +++--- drivers/cpufreq/cpufreq.c | 66 ++++++++++++---------------------- drivers/cpufreq/cpufreq_ondemand.c | 25 ++++++------- drivers/cpufreq/cpufreq_ondemand.h | 1 - drivers/cpufreq/cpufreq_stats.c | 3 +- drivers/cpufreq/freq_table.c | 35 +++++++++--------- drivers/cpufreq/powernv-cpufreq.c | 5 ++- drivers/cpufreq/ppc_cbe_cpufreq_pmi.c | 3 +- drivers/cpufreq/s3c24xx-cpufreq.c | 33 ++++------------- drivers/cpufreq/s5pv210-cpufreq.c | 8 ++--- drivers/thermal/cpu_cooling.c | 22 +++++++++--- include/linux/cpufreq.h | 6 +--- 13 files changed, 88 insertions(+), 137 deletions(-) -- 2.7.1.410.g6faf27b

[PATCH V2 0/2] cpufreq: Use sorted frequency tables

by Viresh Kumar

Hi Guys, This work in inspired by some of the concerns raised by Steve in one of his patchset. Currently, the cpufreq drivers aren't required to provide a sorted list of frequencies to the cpufreq-core and so traversing that list match a target frequency is very inefficient. This is not bearable by, for example, the fast-switch path of schedutil governor and so we have moved the traversing logic local to the acpi-cpufreq driver for now. That is better handled in the core, but it has to be efficient first. OTOH, even for traditional governors without a fast-switch path, it would be much better to be able to traverse this table quickly. The ideal solution would be to keep a single *sorted* freq-table in struct cpufreq_policy. But there are few dependencies due to which it can't be done today (Hint: cpufreq drivers are abusing the 'index' passed to them, to refer to multiple arrays). And so for now, lets create a separate table local to the cpufreq-core *only*. This modifies the existing API cpufreq_frequency_table_target() to use the sorted table. Lightly tested on Exynos board, frequencies were getting selected as expected. V1->V2: - This optimizes cpufreq_frequency_table_target() instead of new APIs. - Is rebased over bleeding-edge + following cleanup series.

[PATCH 00/11] cpufreq: Keep policy->freq_table sorted

by Viresh Kumar

Hi Rafael, This series fixes all cpufreq drivers that provide a 'target_index' callback or in other words, which provide a freq-table to cpufreq core, to make sure they *only* use the 'index' argument to ->target_index() with the policy->freq_table. This change allows us to remove the (duplicate) sorted-freq-table, which was added by following series: [PATCH V2 0/2] cpufreq: Use sorted frequency tables The final code looks like this: - drivers provide a freq table to the cpufreq core - core makes a copy of that and sort that in ascending order of frequencies. This is what we get from policy->freq_table. - drivers can now free the freq-table they provided earlier. - ->target_index() contains the 'index' to this sorted policy->freq_table. This is based of the two series I have posted until now: [PATCH V2 0/6] cpufreq: cleanups and reorganization [PATCH V2 0/2] cpufreq: Use sorted frequency tables All the patches are pushed here for testing in case anyone wants to try: git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/sorted-freq-table The 3 series combined makes freq-table traversing to find a match really fast and efficient. Which will also allow us to use it for new governors like schedutil. -- viresh Viresh Kumar (11): ARM: davinci: Sort frequency table cpufreq: davinci: Reuse cpufreq_generic_frequency_table_verify() cpufreq: Use policy->freq_table in ->target_index() cpufreq: blackfin: Use 'index' only to index into policy->freq_table cpufreq: elanfreq: Use 'index' only to index into policy->freq_table cpufreq: exynos: Use 'index' only to index into policy->freq_table cpufreq: ia64: Use 'index' only to index into policy->freq_table cpufreq: imx: Use 'index' only to index into policy->freq_table cpufreq: maple: Use 'index' only to index into policy->freq_table cpufreq: Keep a single (sorted) freq_table cpufreq: drivers: Free frequency tables after being used arch/arm/mach-davinci/da850.c | 16 ++++++++------- drivers/cpufreq/acpi-cpufreq.c | 7 +++---- drivers/cpufreq/arm_big_little.c | 2 +- drivers/cpufreq/at32ap-cpufreq.c | 8 ++++---- drivers/cpufreq/blackfin-cpufreq.c | 17 +++++++++++----- drivers/cpufreq/cpufreq-dt.c | 9 ++++----- drivers/cpufreq/cpufreq.c | 6 +----- drivers/cpufreq/cris-artpec3-cpufreq.c | 2 +- drivers/cpufreq/cris-etraxfs-cpufreq.c | 2 +- drivers/cpufreq/davinci-cpufreq.c | 22 +-------------------- drivers/cpufreq/dbx500-cpufreq.c | 3 ++- drivers/cpufreq/e_powersaver.c | 26 +++++++++++++----------- drivers/cpufreq/elanfreq.c | 8 +++++++- drivers/cpufreq/exynos5440-cpufreq.c | 13 ++++++++---- drivers/cpufreq/freq_table.c | 36 +++++++++++++--------------------- drivers/cpufreq/ia64-acpi-cpufreq.c | 16 ++++++++++----- drivers/cpufreq/imx6q-cpufreq.c | 13 +++++++++--- drivers/cpufreq/kirkwood-cpufreq.c | 2 +- drivers/cpufreq/loongson1-cpufreq.c | 10 +--------- drivers/cpufreq/loongson2_cpufreq.c | 5 ++--- drivers/cpufreq/maple-cpufreq.c | 6 ++++++ include/linux/cpufreq.h | 9 ++------- 22 files changed, 117 insertions(+), 121 deletions(-) -- 2.7.1.410.g6faf27b

[PATCH] mm: check the return value of lookup_page_ext for all call sites

by Yang Shi

Per the discussion with Joonsoo Kim [1], we need check the return value of lookup_page_ext() for all call sites since it might return NULL in some cases, although it is unlikely, i.e. memory hotplug. Tested with ltp with "page_owner=0".

[PATCH 0/8] cpufreq: cleanups and reorganization

by Viresh Kumar

Hi Rafael, This cleans up cpufreq core and few platform drivers a bit. Its mostly around cleaning up the usage of cpufreq_frequency_table_target(), which will be optimized in a later series. This is just preparatory cleanup for that. Also note that the 4th patch was sent earlier as well in a different form and this is V3 of that. Viresh Kumar (8): ARM: s3c24xx: Sort cpufreq tables cpufreq: s3c24xx: Remove useless checks cpufreq: powerenv: Fix memory leak cpufreq: Remove cpufreq_frequency_get_table() cpufreq: ondemand: Don't keep a copy of freq_table pointer cpufreq: Drop freq-table param to cpufreq_frequency_table_target() cpufreq: Drop 'freq_table' argument of __target_index() cpufreq: Return index from cpufreq_frequency_table_target() Documentation/cpu-freq/cpu-drivers.txt | 8 ++-- arch/arm/mach-s3c24xx/pll-s3c2410.c | 3 +- arch/arm/mach-s3c24xx/pll-s3c2440-12000000.c | 1 + arch/arm/mach-s3c24xx/pll-s3c2440-16934400.c | 1 + drivers/cpufreq/amd_freq_sensitivity.c | 10 ++--- drivers/cpufreq/cpufreq.c | 66 ++++++++++------------------ drivers/cpufreq/cpufreq_ondemand.c | 25 +++++------ drivers/cpufreq/cpufreq_ondemand.h | 1 - drivers/cpufreq/cpufreq_stats.c | 3 +- drivers/cpufreq/freq_table.c | 35 +++++++-------- drivers/cpufreq/powernv-cpufreq.c | 18 ++++---- drivers/cpufreq/ppc_cbe_cpufreq_pmi.c | 3 +- drivers/cpufreq/s3c24xx-cpufreq.c | 33 +++----------- drivers/cpufreq/s5pv210-cpufreq.c | 8 +--- drivers/thermal/cpu_cooling.c | 22 +++++++--- include/linux/cpufreq.h | 6 +-- 16 files changed, 100 insertions(+), 143 deletions(-) -- 2.7.1.410.g6faf27b
