drivers/perf: hisi: Simplify hisi_read_sccl_and_ccl_id and its comment

2020-01-10T15:58:57+00:00

hisi_read_sccl_and_ccl_id is not readable and its comment is a little confused, so simplify the function and its comment as Mark's suggestion. Acked-by: Mark Rutland Reviewed-by: John Garry Suggested-by: Mark Rutland Signed-off-by: Shaokun Zhang Signed-off-by: Will Deacon

drivers/perf: hisi: update the sccl_id/ccl_id for certain HiSilicon platform

2019-11-07T13:07:55+00:00

For some HiSilicon platform, the originally designed SCCL_ID and CCL_ID are not satisfied with much rich topology when the MT is set, so we extend the SCCL_ID to MPIDR[aff3] and CCL_ID to MPIDR[aff2]. Let's update this for HiSilicon uncore PMU driver. Cc: John Garry Cc: Hanjun Guo Cc: Mark Rutland Cc: Will Deacon Signed-off-by: Shaokun Zhang Signed-off-by: Will Deacon

perf: Remove dev_err() usage after platform_get_irq()

2019-07-31T16:15:20+00:00

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).

drivers/perf: hisi: Fixup one DDRC PMU register offset

2019-01-04T10:13:27+00:00

For DDRC PMU, each PMU counter is fixed-purpose. There is a mismatch between perf list and driver definition on rw_chg event. # perf list | grep chg hisi_sccl1_ddrc0/rnk_chg/ [Kernel PMU event] hisi_sccl1_ddrc0/rw_chg/ [Kernel PMU event] But the register offset of rw_chg event is not defined in the driver, meanwhile bnk_chg register offset is mis-defined, let's fixup it.

MT bit in MPIDR_EL1 is now supported in certain HiSilicon platforms, so the mapping between sccl_id/ccl_id and affinity level needs to be updated from the generic encoding we originally used.

perf: Fix sibling iteration

2018-03-16T19:44:12+00:00

Mark noticed that the change to sibling_list changed some iteration semantics; because previously we used group_list as list entry, sibling events would always have an empty sibling_list. But because we now use sibling_list for both list head and list entry, siblings will report as having siblings. Fix this with a custom for_each_sibling_event() iterator.
