We show the streams separately. They are divided into different sections.
1. "Matched hot streams"
2. "Hot streams in old perf data only"
3. "Hot streams in new perf data only".
For each stream, we report the cycles and hot percent (hits%).
For example,

Stream is the branch history which is aggregated by the branch

Hi.
The first part is to document DT bindings for Keem Bay eMMC PHY.
The second is the driver file, loosely based on phy-rockchip-emmc.c
and phy-intel-emmc.c. The latter is not being reused as there are
quite a number of differences i.e. registers offset, supported clock
rates, bitfield to set.
This change has 2 parts:
1. Add support for profiles mode settings.
This allows different fan settings for trip point temp/hyst/pwm.
T194 has multiple fan-profiles support.
2. Add pwm-fan remove support. This is essential since the config is
tristate capable.

When I searched percpu data touched by entry code for #DB
protection[1], it seems to me RESTORE_CR3() does too much work,
this patchset simplifies it.
Patch 1 enhances 21e944591102("x86/mm: Optimize RESTORE_CR3") for
kernel CR3.
Patch 2 *reverts* 21e944591102("x86/mm: Optimize RESTORE_CR3") for
U
RESTORE_CR3 is called when CPL==0 or #DF, it is unlikely
CPL==0&cr3==userCR3 and #DF itself is unlikely case.
There is no much overhead to always flush userCR3.

The nvme host and target verify the wwnn and wwpn format via
nvme_fc_parse_traddr(). For instance, it is required that the length of
wwnn to be either 21 ("nn-0x") or 19 (nn-).
Add this verification to nvme-fcloop so that the input should always be in
hex and the length of input should always be 1

What about older Elaan parts? We can't simply drop compatibility with
older chips in newer kernels.
Thanks.

Controller ID info got by VSC EDL_PATCH_GETVER is very
important, so improve its log level from DEBUG to INFO.

The INTF_INPUT_CTRL feature is not available on sdm845, so don't set it.
This also adds separate feature bits for INTF (based on downstream) instead
of using CTL feature bit for it, and removes the unnecessary NULL check in
the added bind_pingpong_blk function.

This brings up basic video mode functionality for SM8150 DPU. Command mode

address this. Scaler functionality and multiple planes is also untested.

Update the UBWC registers to the right values for sm8150 and sm8250.
This removes broken dpu_hw_reset_ubwc, which doesn't work because the
"force blk offset to zero to access beginning of register region" hack is
copied from downstream, where mapped region starts 0x1000 below what is
used in the u
This isn't something that ever changes between planes, so move it to
dpu_caps struct. Making this change will allow more re-use in the
"SSPP sub blocks config" part of the catalog, in particular when adding
support for SM8150 and SM8250 which have different max_linewidth.
This also sets max_hdeci_
All DPU versions starting from 4.0 use the sdm845 version, so check for
that instead of checking each version individually. This chooses the right
