8549a26 David Howells 10 August 2022, 17:52:47 UTC 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.

7391db6 Carsten Haitzler 12 August 2022, 12:16:28 UTC 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.

d0313e6 Ian Rogers 12 August 2022, 23:09:49 UTC 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.

9118259 Ian Rogers 12 August 2022, 23:09:48 UTC perf jevents: Compress the pmu_events_table The pmu_events array requires 15 pointers per entry which in position independent code need relocating. Change the array to be an array of offsets within a big C string. Only the offset of the first variable is required, subsequent variables are stored in order after the \0 terminator (requiring a byte per variable rather than 4 bytes per offset). 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.

8f5cb44 Atish Patra 22 July 2022, 16:50:47 UTC 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.

This commit changes the behavior of the parameter to make effect for every connect, so that the previous behavior of 'blkfront' can be restored.

fc9be61 SeongJae Park 15 July 2022, 22:51:06 UTC xen-blkback: fix persistent grants negotiation Persistent grants feature can be used only when both backend and the frontend supports the feature. The feature was always supported by 'blkback', but commit aac8a70db24b ("xen-blkback: add a parameter for disabling of persistent grants") has introduced a parameter for disabling it runtime. To avoid the parameter be updated while being used by 'blkback', the commit caches the parameter into 'vbd->feature_gnt_persistent' in 'xen_vbd_create()', and then check if the guest also supports the feature and finally updates the field in 'connect_ring()'. However, 'connect_ring()' could be called before 'xen_vbd_create()', so later execution of 'xen_vbd_create()' can wrongly overwrite 'true' to 'vbd->feature_gnt_persistent'. As a result, 'blkback' could try to use 'persistent grants' feature even if the guest doesn't support the feature. This commit fixes the issue by moving the parameter value caching to 'xen_blkif_alloc()', which allocates the 'blkif'. Because the struct embeds 'vbd' object, which will be used by 'connect_ring()' later, this should be called before 'connect_ring()' and therefore this should be the right and safe place to do the caching.

So we should jump to the link address before PG enabled (because DA is disabled at the same time) and just after DMW configured. Specifically: With some older firmwares, non-boot CPUs started with PG enabled, but this need firmware cooperation in the form of a temporary page table, which is deemed unnecessary. OTOH, latest firmware versions configure the non-boot CPUs to start in DA mode, so kernel-side changes are needed.
