powerpc/powernv: Add a kmsg_dumper that flushes console output on panic On BMC machines, console output is controlled by the OPAL firmware and is only flushed when its pollers are called. When the kernel is in a panic state, it no longer calls these pollers and thus console output does not completely flush, causing some output from the panic to be lost. Output is only actually lost when the kernel is configured to not power off or reboot after panic (i.e. CONFIG_PANIC_TIMEOUT is set to 0) since OPAL flushes the console buffer as part of its power down routines. Before this patch, however, only partial output would be printed during the timeout wait. This patch adds a new kmsg_dumper which gets called at panic time to ensure panic output is not lost. It accomplishes this by calling OPAL_CONSOLE_FLUSH in the OPAL API, and if that is not available, the pollers are called enough times to (hopefully) completely flush the buffer. The flushing mechanism will only affect output printed at and before the kmsg_dump call in kernel/panic.c:panic(). As such, the "end Kernel panic" message may still be truncated as follows: >Call Trace: >[c000000f1f603b00] [c0000000008e9458] dump_stack+0x90/0xbc (unreliable) >[c000000f1f603b30] [c0000000008e7e78] panic+0xf8/0x2c4 >[c000000f1f603bc0] [c000000000be4860] mount_block_root+0x288/0x33c >[c000000f1f603c80] [c000000000be4d14] prepare_namespace+0x1f4/0x254 >[c000000f1f603d00] [c000000000be43e8] kernel_init_freeable+0x318/0x350 >[c000000f1f603dc0] [c00000000000bd74] kernel_init+0x24/0x130 >[c000000f1f603e30] [c0000000000095b0] ret_from_kernel_thread+0x5c/0xac >---[ end Kernel panic - not This functionality is implemented as a kmsg_dumper as it seems to be the most sensible way to introduce platform-specific functionality to the panic function.

powerpc/powernv: Introduce sysfs control for fastsleep workaround behavior Fastsleep is one of the idle state which cpuidle subsystem currently uses on power8 machines. In this state L2 cache is brought down to a threshold voltage. Therefore when the core is in fastsleep, the communication between L2 and L3 needs to be fenced. But there is a bug in the current power8 chips surrounding this fencing. OPAL provides a workaround which precludes the possibility of hitting this bug. But running with this workaround applied causes checkstop if any correctable error in L2 cache directory is detected. Hence OPAL also provides a way to undo the workaround. In the existing implementation, workaround is applied by the last thread of the core entering fastsleep and undone by the first thread waking up. But this has a performance cost. These OPAL calls account for roughly 4000 cycles everytime the core has to enter or wakeup from fastsleep. This patch introduces a sysfs attribute (fastsleep_workaround_applyonce) to choose the behavior of this workaround. By default, fastsleep_workaround_applyonce = 0. In this case, workaround is applied/undone everytime the core enters/exits fastsleep. fastsleep_workaround_applyonce = 1. In this case the workaround is applied once on all the cores and never undone. This can be triggered by echo 1 > /sys/devices/system/cpu/fastsleep_workaround_applyonce For simplicity this attribute can be modified only once. Implying, once fastsleep_workaround_applyonce is changed to 1, it cannot be reverted to the default state. Signed-off-by: Shreyas B.
