There have been some cases where external tooling (e.g., kpatch-build)
creates a corrupt relocation which targets the wrong address. This is a
silent failure which can corrupt memory in unexpected places.
On x86, the bytes of data being overwritten by relocations are always

This patch adds a LCD driver supporting the OTM3225A LCD SoC
from ORISE Technology. This device can drive TFT LC panels having a
resolution of 240x320 pixels. After initializing the OTM3225A using

Certain SoCs need to map the MSI address in raise_irq.
To map an address, you first need to call pci_epc_mem_alloc_addr(),
however, pci_epc_mem_alloc_addr() calls ioremap() (which can sleep).
Since raise_irq is only called from atomic context, we can't call
pci_epc_mem_alloc_addr() from
Use the DMA-API to get the MSI address. This address will be written to

to write to the MSI address,
Previously, dw_pcie_ep_set_msi() wrote all bits in the Message Control

Introduce a new option to dump trace output to files named by the
monitored events and update perf-script documentation accordingly.
Shown below is output of perf script command with the newly introduced
option.

We will use it to generate tables for beautifying prctl's 'option' arg
and some of the others eventually.

Milian Wolff found a problem he described in [1] and that for him would

We should support this because it would allow easily to collect metrics

For some unknown reason there is no entry in tracefs's syscalls for
kcmp, i.e. no tracefs/events/syscalls/sys_{enter,exit}_kcmp, so we need
to provide a data dictionary for the fields.

When libbfd is not used, addr2inlines() executes `addr2line -i` and
process output line by line. But it resets filename to NULL in the loop
so getline() allocates additional memory everytime instead of realloc.

When libbfd is not used, it doesn't show proper function name and reuse
the original symbol of the sample. That's because it passes the
original sym to inline_list__append(). As `addr2line -f` returns
function names as well, use that to create an inline_sym and pass it to

Move the shadow stats scale computation to the
perf_stat__update_shadow_stats() function, so it's centralized and we
don't forget to do it. It also saves few lines of code.

Rename struct perf_data_file to perf_data, because we will add the
possibility to have multiple files under perf.data, so the 'perf_data'
name fits better.

When we started using it for stats and did it not just in
builtin-stat.c, but also for builtin-script.c, then it stopped being a
tool private area, so introduce a new pointer for these stats and leave
