[PATCH OLK-6.6] irqdomain: Fix driver re-inserting failures when IRQs not being freed
by Jie Zhan 09 Apr '24

09 Apr '24

driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9ERMB ------------------------------------------------------------------------ Since commit 4615fbc3788d ("genirq/irqdomain: Don't try to free an interrupt that has no mapping"), we have found failures when re-inserting some specific drivers: [root@localhost ~]# rmmod hisi_sas_v3_hw [root@localhost ~]# modprobe hisi_sas_v3_hw [ 1295.622525] hisi_sas_v3_hw: probe of 0000:30:04.0 failed with error -2 A relevant discussion can be found at: https://lore.kernel.org/lkml/3d3d0155e66429968cb4f6b4feeae4b3@kernel.org/ This is because IRQs from a low-level domain are not freed together, leaving some leaked. Thus, the next driver insertion fails to allocate the same number of IRQs. Free a contiguous group of IRQs in one go to fix this issue.
