Hi, arm and arm64 topology.c share a lot of code related to parsing of capacity information. This is v4 of a solution [1] (based on Will's, Catalin's and Mark's off-line suggestions) to move such common code in a single place: drivers/base/arch_topology.c (by creating such file and conditionally compiling it for arm and arm64 only). First 4 patches are actually fixes for the current code. Patch 5 is the actual refactoring. Patch 6 removes one of the extern symbols by changing a bit the now common code. Patch 7 removes the remaining externs (as required by Russell during v1 review) by creating a new header file include/linux/arch_topology.h and including that from arm, arm64 and drivers. Last patch addresses Dietmar's comments to v1 and adds a 'atd_' prefix to interfaces exported by drivers code and used by arch (and potentially others in the future). Changes from v3: - rebase on top of 4.11-rc7 - addressed Vincent's comment on patch 3/8 - removed v3 6/9 as discussed with Russell - added Russell and Catalin's Acked-by The set is based on top of linux/master (4.11-rc7 f61143c45077) and it is also available from: git://linux-arm.org/linux-jl.git upstream/default_caps_factorize-v4 Best, - Juri [1] v1 - https://marc.info/?l=linux-kernel&m=148483680119355&w=2 v2 - https://marc.info/?l=linux-kernel&m=148663344018205&w=2 v3 - http://marc.info/?l=linux-kernel&m=149062080701399&w=2 Juri Lelli (8): Documentation: arm: fix wrong reference number in DT definition Documentation/ABI: add information about cpu_capacity arm: fix return value of parse_cpu_capacity arm: remove wrong CONFIG_PROC_SYSCTL ifdef arm, arm64: factorize common cpu capacity default code arm,arm64,drivers: reduce scope of cap_parsing_failed arm,arm64,drivers: move externs in a new header file arm,arm64,drivers: add a prefix to drivers arch_topology interfaces Documentation/ABI/testing/sysfs-devices-system-cpu | 7 + Documentation/devicetree/bindings/arm/cpus.txt | 4 +- arch/arm/Kconfig | 1 + arch/arm/kernel/topology.c | 221 +------------------ arch/arm64/Kconfig | 1 + arch/arm64/kernel/topology.c | 226 +------------------ drivers/base/Kconfig | 8 + drivers/base/Makefile | 1 + drivers/base/arch_topology.c | 243 +++++++++++++++++++++ include/linux/arch_topology.h | 17 ++ 10 files changed, 290 insertions(+), 439 deletions(-) create mode 100644 drivers/base/arch_topology.c create mode 100644 include/linux/arch_topology.h -- 2.10.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
