[PATCH v9 0/1] hibernation related patches

by Sebastian Capella

Patchset related to hibernation resume: - enhancement to make the use of an existing resume file more general Patch is based on the 3.13 tag. This was tested on a Beaglebone black with partial hibernation support, also compiled for x86_64. [PATCH v9 1/1] PM / Hibernate: use name_to_dev_t to parse resume kernel/power/hibernate.c | 22 ++++++++++++---------- 1 file changed, 12 insertions(+), 10 deletions(-) Use name_to_dev_t to parse the /sys/power/resume file making the syntax more flexible. It supports the previous use syntax and additionally can support other formats such as /dev/devicenode and UUID= formats. By changing /sys/debug/resume to accept the same syntax as the resume=device parameter, we can parse the resume=device in the initrd init script and use the resume device directly from the kernel command line. Changes in v9: -------------- * Dropped util changes based on feedback * Reverted to special newline handling in resume_store Changes in v8: -------------- * Dropped cleanup checkpatch warnings in hibernate.c file * Review comments for more compact checking in hibernate.c Changes in v7: -------------- * Switch to trim only one trailing newline if present using kstrdup_trimnl * remove kstrimdup patch * add kstrdup_trimnl patch * Add clean up patch for kernel/power/hibernate.c checkpatch warnings Changes in v6: -------------- * Revert tricky / confusing while loop indexing Changes in v5: -------------- * Change kstrimdup to minimize allocated memory. Now allocates only the memory needed for the string instead of using strim. Changes in v4: -------------- * Dropped name_to_dev_t rework in favor of adding kstrimdup * adjusted resume_store Changes in v3: -------------- * Dropped documentation patch as it went in through trivial * Added patch for name_to_dev_t to support directly parsing userspace buffer Changes in v2: -------------- * Added check for null return of kstrndup in hibernate.c Thanks, Sebastian

[PATCH] perf: ARM64: wire up perf_regs and unwind support

by Jean Pihet

This patch hooks in the perf_regs and libunwind code for ARM64. The tools/perf/arch/arm64 is created; it contains the arch specific code for DWARF unwinding.
