Subject: [PATCH 23/55] perf: hisi: Make irq shared
|
|
|
|
hulk inclusion
|
|
category: feature
|
|
bugzilla: https://gitee.com/openeuler/kernel/issues/I584X2
|
|
CVE: NA
|
|
|
|
--------------------------------
|
|
|
|
On some platforms, there are some error:
|
|
genirq: Flags mismatch irq 23. 00010804 (xxx) vs. 00010804 (xxx)
|
|
|
|
The reason is that there are more than one pmu nodes witch uses the same
|
|
irq number.
|
|
|
|
Add IROF_SHARED when devm_request_irq
