Subject: [PATCH 0/4] arm64: kgdb/kdb: Fix single-step debugging issues
Date: Sun, 10 May 2020 05:41:55 +0800 [thread overview]
Message-ID: <20200509214159.19680-1-liwei391@huawei.com> (raw)
This patch set is to fix several issues of single-step debugging
in kgdb/kdb on arm64.
It seems that these issues have been shelved a very long time,
but i still hope to solve them, as the single-step debugging
is an useful feature.
Note:
Based on patch "arm64: cacheflush: Fix KGDB trap detection",
https://www.spinics.net/lists/arm-kernel/msg803741.html
Wei Li (4):
arm64: kgdb: Fix single-step exception handling oops
arm64: Extract kprobes_save_local_irqflag() and
kprobes_restore_local_irqflag()
arm64: kgdb: Fix single-stepping into the irq handler wrongly
arm64: kgdb: Set PSTATE.SS to 1 to reenable single-step
