Subject: [PATCH v4 0/6] MIPS: kexec/kdump: Fix smp reboot and other issues
Date: Wed, 5 Sep 2018 08:59:03 -0700 [thread overview]
Message-ID: <20180905155909.30454-1-dzhu@wavecomp.com> (raw)
The issues are mentioned in patches 1/4/5/6. I will update kdump
documentation for MIPS if the series gets accepted. Testing has been done
on single core i6500/Boston with IOCU, dual core i6500 without IOCU, and
dual core interAptiv without IOCU.
Changes:
v4 - v3:
* In patch #1, idle_task_exit() is moved out from play_dead() to its sole
caller arch_cpu_idle_dead(). So no interface change of play_dead().
* In patch #6, the kexec_prepare method for the Generic platform is defined
as uhi_machine_kexec_prepare() for all platforms using UHI boot protocol.
v3 - v2:
* Code style changes according to `scripts/checkpatch.pl --strict`.
Patch #6, like before, still has a warning message reminding if
MAINTAINERS needs updating. But it does NOT involve a maintainer change.
* Add LIBFDT to CPU_LOONGSON3 for default_machine_kexec_prepare().
v2 - v1:
* Tested on MIPS32R2 platform in addition to MIPS64R6.
* Added patches #5 and #6.
* In patch #2, removed the unnecessary inclusion of asm/mipsmtregs.h
Dengcheng Zhu (6):
MIPS: Make play_dead() work for kexec
MIPS: kexec: Let the new kernel handle all CPUs
MIPS: kexec: Deprecate (relocated_)kexec_smp_wait
MIPS: kexec: Do not flush system wide caches in machine_kexec()
MIPS: kexec: Relax memory restriction
MIPS: kexec: Use prepare method from Generic for UHI platforms
