Since panic_timeout is an integer passed-in through sysctl,
the loop boundary panic_timeout * 1000 could overflow and
result in a zero-delay panic when panic_timeout is greater
than INT_MAX/1000.
Fix this by moving 1000 to the left, also in case i/1000
might never be greater

This brings up basic video mode functionality for SM8150 DPU. Command mode
and dual mixer/intf configurations are not working, future patches will
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
These patches bring up SM8150 and SM8250 with basic functionality.
Tested with displayport output (single mixer, video mode case).

Jonathan Marek (8):
drm/msm/dpu: use right setup_blend_config for sm8150 and sm8250
drm/msm/dpu: update UBWC config for sm8150 and sm8250
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
function for sm8150 and sm8250.

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.
Fixes:
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

Some CPUs can speculate past an ERET instruction and potentially perform
speculative accesses to memory before processing the exception return.

Hi Linus, please pull from:

...to receive a coding-style update for v5.9. The discussion has
tapered off as well as the incoming ack, review, and sign-off tags. I
did not see a reason to wait for the next merge
I hit this FTBFS earlier today while trying to build the LT 4.19.132
kernel from source:
https://lore.kernel.org/patchwork/patch/960281/
The "quick hack" patch mentioned at the bottom of the thread gets it
to compile. Is this the correct solution, or is there a better fix? As
it stands,
It's been about two weeks since the last batch of fixes, and it
shows as we clock in here at 146 non-merge commits:
1) Restore previous behavior of CAP_SYS_ADMIN wrt. loading networking
BPF programs, from Maciej Żenczykowski.
2) Fix dropped broadcasts in mac80211 code, from Seevalamuthu
