Hi all,
This series does a number of cleanups into resctrl_val() and generalizes it by removing test name specific handling from the function.
Hopefully these reach also Shuah successfully as I've recently seen rejects for mail from @linux.intel.com to gmail addresses.
v5: - Open mem bw file only once and use rewind(). - Add \n to mem bw file read to allow reading fresh values from the file. - Return 0 if create_grp() is given NULL grp_name (matches the original behavior). Mention this in function's kerneldoc. - Cast pid_t to int before printing with %d. - Caps/typo fixes to kerneldoc and commit messages. - Use imperative tone in commit messages and improve them based on points that came up during review.
v4: - Merged close fix into IMC READ+WRITE rework patch - Add loop to reset imc_counters_config fds to -1 to be able know which need closing - Introduce perf_close_imc_mem_bw() to close fds - Open resctrl mem bw file (twice) beforehand to avoid opening it during the test - Remove MBM .mongrp setup - Remove mongrp from CMT test
v3: - Rename init functions to <testname>_init() - Replace for loops with READ+WRITE statements for clarity - Don't drop Return: entry from perf_open_imc_mem_bw() func comment - New patch: Fix closing of IMC fds in case of error - New patch: Make "bandwidth" consistent in comments & prints - New patch: Simplify mem bandwidth file code - Remove wrong comment - Changed grp_name check to return -1 on fail (internal sanity check)
v2: - Resolved conflicts with kselftest/next - Spaces -> tabs correction
