Stephane Eranian 2de71ee153 perf/x86/intel: Fix ICL/SPR INST_RETIRED.PREC_DIST encodings
This patch fixes the encoding for INST_RETIRED.PREC_DIST as published by Intel
(download.01.org/perfmon/) for Icelake. The official encoding
is event code 0x00 umask 0x1, a change from Skylake where it was code 0xc0
umask 0x1.

With this patch applied it is possible to run:
$ perf record -a -e cpu/event=0x00,umask=0x1/pp .....

Whereas before this would fail.

To avoid problems with tools which may use the old code, we maintain the old
encoding for Icelake.

Kajol Jain 26da4abfb3 powerpc/perf: Fix data source encodings for L2.1 and L3.1 accesses
Fix the data source encodings to represent L2.1/L3.1(another core's
L2/L3 on the same node) accesses properly for power10 and older
plaforms.

Add new macros(LEVEL/REM) which can be used to add mem_lvl_num and remote
field data inside perf_mem_data_src structure.

Result in power9 system with patch changes:

Kajol Jain cae1d75906 tools/perf: Add mem_hops field in perf_mem_data_src structure
Going forward, future generation systems can have more hierarchy
within the node/package level but currently we don't have any data source
encoding field in perf, which can be used to represent this level of data.

Add a new field called 'mem_hops' in the perf_mem_data_src structure
which can be used to represent intra-node/package or inter-node/off-package
details. This field is of size 3 bits where PERF_MEM_HOPS_{NA, 0..6} value
can be used to present different hop levels data.

Also add corresponding macros to define mem_hop field values
and shift value.

Currently we define macro for HOPS_0 which corresponds
to data coming from another core but same node.

Add functionality to represent mem_hop field data in
perf_mem__lvl_scnprintf function with the help of added string
array called mem_hops.

For ex: Encodings for mem_hops fields with L2 cache:

L2                      - local L2
L2 | REMOTE | HOPS_0    - remote core, same node L2

Since with the addition of HOPS field, now remote can be used to
denote cache access from the same node but different core, a check
is added in the c2c_decode_stats function to set mrem only when HOPS
is zero along with set remote field.

Adrian Hunter 8b8ff8cc3b perf/x86: Add new event for AUX output counter index
PEBS-via-PT records contain a mask of applicable counters. To identify
which event belongs to which counter, a side-band event is needed. Until
now, there has been no side-band event, and consequently users were limited
to using a single event.

Add such a side-band event. Note the event is optimised to output only
when the counter index changes for an event. That works only so long as
all PEBS-via-PT events are scheduled together, which they are for a
recording session because they are in a single group.

Also no attribute bit is used to select the new event, so a new
kernel is not compatible with older perf tools.  The assumption
being that PEBS-via-PT is sufficiently esoteric that users will not
be troubled by this.

Colin Ian King 0b3a8738b7 perf/x86/intel/uncore: Fix integer overflow on 23 bit left shift of a u32
The u32 variable pci_dword is being masked with 0x1fffffff and then left
shifted 23 places. The shift is a u32 operation,so a value of 0x200 or
more in pci_dword will overflow the u32 and only the bottow 32 bits
are assigned to addr. I don't believe this was the original intent.
Fix this by casting pci_dword to a resource_size_t to ensure no
overflow occurs.

Note that the mask and 12 bit left shift operation does not need this
because the mask SNR_IMC_MMIO_MEM0_MASK and shift is always a 32 bit
value.

Pull drm fixes from Dave Airlie:
 "Regularly scheduled fixes. The ttm one solves a problem of GPU drivers
  failing to load if debugfs is off in Kconfig, otherwise the i915 and
  mediatek, and amdgpu fixes all fairly normal.

  Nouveau has a couple of display fixes, but it has a fix for a
  longstanding race condition in it's memory manager code, and the fix
  mostly removes some code that wasn't working properly and has no
  userspace users. This fix makes the diffstat kinda larger but in a
  good (negative line-count) way.

   - fix drm_wait_vblank uapi copying bug

  amdgpu:
