| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code tries to store -EFAULT in an unsigned int. The xenbus_file_read() function returns type ssize_t so the negative value is returned as a positive value to the user. This change forces another change to the min() macro. Originally, the min() macro used "unsigned" type which checkpatch complains about. Also unsigned type would break if "len" were not capped at MAX_RW_COUNT. Use size_t for the min(). (No effect on runtime for the min_t() change).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some use cases[1], the backend is created while the frontend doesn't support the persistent grants feature, but later the frontend can be changed to support the feature and reconnect. In the past, 'blkback' enabled the persistent grants feature since it unconditionally checked if frontend supports the persistent grants feature for every connect ('connect_ring()') and decided whether it should use persistent grans or not. However, commit aac8a70db24b ("xen-blkback: add a parameter for disabling of persistent grants") has mistakenly changed the behavior. It made the frontend feature support check to not be repeated once it shown the 'feature_persistent' as 'false', or the frontend doesn't support persistent grants. Similar behavioral change has made on 'blkfront' by commit 74a852479c68 ("xen-blkfront: add a parameter for disabling of persistent grants"). This commit changes the behavior of the parameter to make effect for every connect, so that the previous behavior of 'blkfront' can be restored.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement support for the HVMOP_set_evtchn_upcall_vector hypercall in order to set the per-vCPU event channel vector callback on Linux and use it in preference of HVM_PARAM_CALLBACK_IRQ. If the per-VCPU vector setup is successful on BSP, use this method for the APs. If not, fallback to the global vector-type callback. Also register callback_irq at per-vCPU event channel setup to trick toolstack to think the domain is enlightened.

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.

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.

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.

This way the pmu_event is only needed for one element and not an entire array. Switch existing code iterating over the pmu_event arrays to use the new loop function pmu_events_table_for_each_event.

While the map is passed, the table of events is all that is normally wanted. While modifying the function's types, rename pmu_events_map__find to pmu_events_table__find to match later encapsulation. Similarly rename pmu_add_cpu_aliases_map to pmu_add_cpu_aliases_table.

The sort order tries to replicated cmp_sevent from pmu.c so that the input there is already sorted except for sysfs events. Specifically, the sort order is given by the tuple: (not j.desc is None, fix_none(j.topic), fix_none(j.name), fix_none(j.pmu), fix_none(j.metric_name)) which is putting events with descriptions and topics before those without, then sorting by name, then pmu and finally metric_name Add the topic to JsonEvent on reading to simplify. Remove an unnecessary lambda in the JSON reading.
