perf-buildid-list(1)
====================

NAME
----
perf-buildid-list - List the buildids in a perf.data file

SYNOPSIS
--------
[verse]
'perf buildid-list <options>'

DESCRIPTION
-----------
This command displays the buildids found in a perf.data file, so that other
tools can be used to fetch packages with matching symbol tables for use by
perf report.

It can also be used to show the build id of the running kernel or in an ELF
file using -i/--input.

OPTIONS
-------
-H::
--with-hits::
        Show only DSOs with hits.
-i::
--input=::
        Input file name. (default: perf.data unless stdin is a fifo)
-f::
--force::
	Don't do ownership validation.
-k::
--kernel::
	Show running kernel build id.
-v::
--verbose::
	Be more verbose.

PCI/MSI: Don't apply affinity if there aren't enough vectors left
Bart reported a problem wіth an out of bounds access in the low-level IRQ affinity code, which we root caused to the qla2xxx driver assigning all its MSI-X vectors to the pre and post vectors, and not having any left for the actually spread IRQs. Fix this issue by not asking for affinity assignment when there are no vectors to assign left.
