I will apply this to linux-kbuild since this depends on
another patch there.
Sure.
Add a 'percore' event qualifier, like cpu/event=0,umask=0x3,percore=1/,
that sums up the event counts for both hardware threads in a core.
We can already do this with --per-core, but it's often useful to do
this together with other metrics that are collected per hardware thread.
So we need to
The 'percore' event qualifier which sums up the event counts for both
hardware threads in a core. For example,
perf stat -e cpu/event=0,umask=0x3,percore=1/,cpu/event=0,umask=0x3/
In this example, we count the event 'ref-cycles' per-core and per-CPU in
one perf stat command-line.
We can already

The error return path via label rel_resource checks for a non-null
skb before free'ing it. However, skb is always null at this exit
path, so the null check and the free are redundant and can be removed.
Removing this allows the original goto's to rel_resource to be cleaned

It's confused that R/W some registers by csr_readl()/csr_writel(),
while others by read_paged_register()/write_paged_register().
Actually the lower 3KB of 4KB PCIe configure space can be accessed
directly and higher 1KB is paging area. So this patch unifies the
register

It should get PCI base address from the 'ranges' property of DT node
