Nothing ever reads pmc logs out of a counting PMC, so the log buffers were leaked when the PMC was deconfigured. The process mappings are only useful for sampling PMCs anyway, so only log the mappings if the PMC is a sampling PMC. This bug would cause allocating sample-mode PMCs to fail with ENOMEM after allocating several counting-mode PMCs.

There is some removed events in the documentation, they have been kept in the code but documented in the man page as obsolete. - Offcore response events can be setup with rsp token.

This will indirectly fix a bug where the thread will be pinned forever if the assert is not compiled. 2010-03-29T06:55:38Z Fabien Thomas fabient@FreeBSD.org 2010-03-29T06:55:38Z urn:sha1:44a4e1d8fb8f69863493cc375bf5668976622dff Handling SIGPIPE will cause deadlock/crash. Return an error immediatly in case of hard shutdown. 2010-03-11T07:35:30Z Fabien Thomas fabient@FreeBSD.org 2010-03-11T07:35:30Z urn:sha1:4e0c5d79a0aa5fa7109e017111c07d0ce1988de2 Change the way shutdown is handled for log file. pmc_flush_logfile is now non-blocking and just ask the kernel to shutdown the file. From that point, no more data is accepted by the log thread and when the last buffer is flushed the file is closed. This will remove a deadlock between pmcstat asking for flush while it cannot flush the pipe itself. 2010-01-10T16:08:14Z Fabien Thomas fabient@FreeBSD.org 2010-01-10T16:08:14Z urn:sha1:40095a24edebf3b01e0bbf5ddac944cb2c482686 Use VFS_{LOCK,UNLOCK}_GIANT() around the call to vrele(). 2010-01-10T16:04:32Z Fabien Thomas fabient@FreeBSD.org 2010-01-10T16:04:32Z urn:sha1:a267011a08d5da690383ee1275de08578419066d * Support the L1D_CACHE_LD event on Core2 processors. * Correct a group of typos: for Core2 programmable events, check user supplied umask values against the correct event descriptor field. 2010-01-10T16:00:00Z Fabien Thomas fabient@FreeBSD.org 2010-01-10T16:00:00Z urn:sha1:cd56dc4253eb0f193fc0c1b23b2113b4d9b6f4a6 Log process mappings for existing processes at PMC start time. 2009-12-11T12:36:02Z Fabien Thomas fabient@FreeBSD.org 2009-12-11T12:36:02Z urn:sha1:68d2ef77eb3795733f819822ecd701b847c9b581 Add counters for the i7 architecture which were accidentally left out of the original commit of i7 support. These are all the counters on pages A-32 and A-33 of the _Intel(R) 64 and IA32 Architectures Software Developer's Manual Vol 3B_, June 2009. Almost all of these counters relate to operations on the L2 cache. 2009-12-07T20:49:49Z Fabien Thomas fabient@FreeBSD.org 2009-12-07T20:49:49Z urn:sha1:86cff089e71c766a2e1f57155c3086370e228757 Use a better check for a valid kernel stack address when capturing kernel call chains.
