2021-06-02docs: fix references to docs/devel/tracing.rstStefano Garzarella1-1/+1
Commit e50caf4a5c ("tracing: convert documentation to rST") converted docs/devel/tracing.txt to docs/devel/tracing.rst. We still have several references to the old file, so let's fix them with the following command: sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt) Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210517151702.109066-2-sgarzare@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

2019-03-22trace-events: Fix attribution of trace points to sourceMarkus Armbruster1-2/+4
Some trace points are attributed to the wrong source file. Happens when we neglect to update trace-events for code motion, or add events in the wrong place, or misspell the file name. Clean up with help of cleanup-trace-events.pl. Same funnies as in the previous commit, of course. Manually shorten its change to linux-user/trace-events to */signal.c.

2019-03-22trace-events: Delete unused trace pointsMarkus Armbruster1-1/+0
Tracked down with cleanup-trace-events.pl. Funnies requiring manual post-processing: * block.c and blockdev.c trace points are in block/trace-events. * hw/block/nvme.c uses the preprocessor to hide its trace point use from cleanup-trace-events.pl. * include/hw/xen/xen_common.h trace points are in hw/xen/trace-events. * net/colo-compare and net/filter-rewriter.c use pseudo trace points colo_compare_udp_miscompare and colo_filter_rewriter_debug to guard debug code.

2019-03-22trace-events: Shorten file names in commentsMarkus Armbruster1-8/+8
We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.

2018-06-08ide: push end_transfer_func out of start_transfer callback, rename callbackPaolo Bonzini1-1/+1
Now that end_transfer_func is a tail call in ahci_start_transfer, formalize the fact that the callback (of which ahci_start_transfer is the sole implementation) takes care of the transfer too: rename it to pio_transfer and, if it is present, call the end_transfer_func as soon as it returns.

2018-06-08ahci: make port read traces more descriptiveJohn Snow1-1/+2
A trace is added to let us watch unimplemented registers specifically, as these are more likely to cause us trouble. Otherwise, the port read traces now tell us what register is getting hit, which is nicer.

2017-09-18AHCI: Rework IRQ constantsJohn Snow1-1/+1
Create a new enum so that we can name the IRQ bits, which will make debugging them a little nicer if we can print them out. Not handled in this patch, but this will make it possible to get a nice debug printf detailing exactly which status bits are set, as it can be multiple at any given time. As a consequence of this patch, it is no longer possible to set multiple IRQ codes at once, but nothing was utilizing this ability anyway.
