Update the instructions for enabling and disabling read access to the
special sysfs 'rom' file for PCI devices. The function that interprets
user data for enabling and disabling the device actually expects _at
least_ 2 bytes, more than what is expressly implied by "1" or "0".
It should also be no

Doing this with coccinelle would have been nicer but this is small
enough to review without too much fatigue :)

Yes, either one works. In the interrupt driven mode, som
Hi Stef,
Thanks for sharing your time to test it.
That is expected result in v2. Previously in v1, it used delayed
creation on core temperature group so it was okay if hwmon driver is
registered when client CPU is powered down, but in v2, the driver should
check resolved cores at probing time

map_info is very generic name, rename it to uprobe_map_info.
Renaming will help to export this structure outside of the
file.
Also rename free_map_info() to uprobe_free_map_info() and
build_map_info() to uprobe_build_map_info().

With this, perf buildid-cache will save SDT markers with reference
counter in probe cache. Perf probe will be able to probe markers
having reference counter. Ex,

Name: loop2
... Semaphore: 0x10020036
# ./perf buildid-cache --add /tmp/tic

Hi Jae,
I tried version 1 and 2 of your PECI patch on our (AST2500 / Xeon E5 v4)
system. The V1 patchset works as expected (reading back temperature 0
until PECI is up), but the hwmon driver probe fails with version 2. It
communicates with the Xeon and assumes during kernel boot of the Aspeed

I will queue it for 4.17, with just one minor fix below.
