Patch Set 2: Code-Review+2
(1 comment)
File src/acpi/acpi.c:
https://review.coreboot.org/c/coreboot/+/76293/comment/09cfd053_eded3e61 :
PS2, Line 1633: | (uint64_t)fadt->x_firmware_ctl_h << 32);
For some reason, src/southbridge/amd/pi/hudson/fadt.c has this:
fadt->x_firmware_ctl_l = 0; /* set to 0 if firmware_ctrl is used */
fadt->x_firmware_ctl_h = 0;
The only hardware using this now, pcengines/apu[2..6] do not support S3 but I think this change would break S3 resume if FACS was ever located above 4G.

soc/intel/meteorlake: Hook up UPD for C1 C-state auto-demotion
FSP has a parameter to enable/disable c1-state autodemotion feature.
Boards/Baseboard can choose to use this feature as per requirement.
This patch hooks up this parameter to devicetree.
BUG=b:286328295
TEST=Check code compiles & boot google/rex, and correct value has been
passed to FSP.

Hello Jakub Czapiga, Kapil Porwal, Subrata Banik, Tarun Tuli, build bot (Jenkins),
I'd like you to reexamine a change. Please visit

to look at the new patch set (#4).

Change subject: mb/google/{rex,ovis}: Disable C1-state auto demotion for rex & ovis
......................................................................
mb/google/{rex,ovis}: Disable C1-state auto demotion for rex & ovis
C1-state auto demotion feature allows hardware to determine C1-state
as per platform policy. Since platform sets performance policy to
balanced from hardware, auto demotion can be disabled without
performance impact.
Also, disabling this feature results soc to enter PC2 and lower
state in camera preview case and save platform power.
Note: C1 demotion heuristics used EPB parameter to balance between power
and performance, i.e. low threshold when EPB is low in-order to get C1
demotion faster and vice-versa. ChromeOS operates at default EPB=0x7
(low EPB) in both AC/DC, so in DC mode it gets more C1 demotion hits
than expected (similar to AC mode) and losing power respectively.
BUG=b:286328295
TEST=Code compiles and correct value of c1-state auto demotion is
passed to FSP. Also verified PC residency improvement ~10% in
camera preview case.
