EDAC driver used the hardcoded register offsets. But this caused crash
on SM8450 SoC where the register offsets has been changed.

So to avoid this crash and also to make it easy to accommodate changes for
new SoCs, let's pass the LLCC version specific register offsets to the
EDAC driver.

Currently, two set of offsets are used. One is starting from LLCC version
v1.0.0 used by all SoCs other than SM8450. For SM8450, LLCC version
starting from v2.1.0 is used.

soc: qcom: llcc: Rename reg_offset structs to reflect LLCC version

The register offsets used by the LLCC block retains its layout for multiple
versions. For instance, starting from version v1.0.0 to v2.0.1 the offsets
are same. And starting from v2.1.0, the offsets changed.

But the current reg_offset naming convention is confusing. So to reflect
this change correctly in driver, let's encode the start version from which
the offsets got changed in reg_offset struct name. This will be
llcc_v1_reg_offset for v1.0.0 and llcc_v2_1_reg_offset for v2.1.0.
This will allow multiple SoCs to use the same reg_offset clearly.

And in the future if the offsets got changed again, then that specific
version could be encoded in the struct name.

afs: Enable multipage folio support

Enable multipage folio support for the afs filesystem.

Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.

Note that it does require a change to afs_write_begin() to return the
correct subpage.  This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.

2 years agoperf test: Refactor shell tests allowing subdirs
Carsten Haitzler [Fri, 12 Aug 2022 12:16:28 +0000 (13:16 +0100)]
perf test: Refactor shell tests allowing subdirs

This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.

To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.

This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).

It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).

This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.

2 years agoperf jevents: Fold strings optimization
Ian Rogers [Fri, 12 Aug 2022 23:09:49 +0000 (16:09 -0700)]
perf jevents: Fold strings optimization

If a shorter string ends a longer string then the shorter string may
reuse the longer string at an offset. For example, on x86 the event
arith.cycles_div_busy and cycles_div_busy can be folded, even though
they have difference names the strings are identical after 6
characters. cycles_div_busy can reuse the arith.cycles_div_busy string
at an offset of 6.

In pmu-events.c this looks like the following where the 'also:' lists
folded strings:

/* offset=177541 */ "arith.cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000" /* also: cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000 */

As jevents.py combines multiple strings for an event into a larger
string, the amount of folding is minimal as all parts of the event must
align. Other organizations can benefit more from folding, but lose space
by say recording more offsets.

The file size savings are:

no jevents - the same 19,788,464bytes
x86 jevents - ~16.7% file size saving 23,744,288bytes vs 28,502,632bytes
all jevents - ~19.5% file size saving 24,469,056bytes vs 30,379,920bytes
default build options plus NO_LIBBFD=1.

For example, the x86 build savings come from .rela.dyn and
.data.rel.ro becoming smaller by 3,157,032bytes and 3,042,016bytes
respectively. .rodata increases by 1,432,448bytes, giving an overall
4,766,600bytes saving.

To make metric strings more shareable, the topic is changed from say
'skx metrics' to just 'metrics'.

To try to help with the memory layout the pmu_events are ordered as used
by perf qsort comparator functions.

When the CONFIG_PORTABLE/CONFIG_NONPORTABLE switches were added, various
configs were updated, but the wireguard config was forgotten about. This
leads to unbootable test kernels, causing CI fails. Add

RISC-V: KVM: Support sstc extension

Sstc extension allows the guest to program the vstimecmp CSR directly
instead of making an SBI call to the hypervisor to program the next
event. The timer interrupt is also directly injected to the guest by
the hardware in this case. To maintain backward compatibility, the
hypervisors also update the vstimecmp in an SBI set_time call if
the hardware supports it. Thus, the older kernels in guest also
take advantage of the sstc extension.
