https://review.coreboot.org/c/coreboot/+/40331/7/src/northbridge/intel/i945/... File src/northbridge/intel/i945/raminit.c:

https://review.coreboot.org/c/coreboot/+/40331/7/src/northbridge/intel/i945/... PS7, Line 2149: PCI_DEV(0, 0x00, 0) Only `0x0`? Is there a macro for the expression?

https://review.coreboot.org/c/coreboot/+/40331/7/src/northbridge/intel/i945/... PS7, Line 2305: #ifdef C2_SELF_REFRESH_DISABLE Afterward set `integrated_graphics` down here, so it’s closer to the usage?

NB: That macro does not exist (commit 71a3d96bc (* drop ich7 include)).

https://review.coreboot.org/c/coreboot/+/40331/7/src/northbridge/intel/i945/... PS7, Line 2308: printk(BIOS_DEBUG, "C2 self-refresh with IGD\n"); Isn’t that the disabled branch of `ifdef`?

...

Only `0x0`? Is there a macro for the expression?

I don't think so for i945

git grep 'PCI_DEV(0, 0x00, 0)' |grep i945

https://review.coreboot.org/c/coreboot/+/40331/7/src/northbridge/intel/i945/... PS7, Line 2305: #ifdef C2_SELF_REFRESH_DISABLE

...

Afterward set `integrated_graphics` down here, so it’s closer to the usage? […]

Ack

https://review.coreboot.org/c/coreboot/+/40331/7/src/northbridge/intel/i945/... PS7, Line 2308: printk(BIOS_DEBUG, "C2 self-refresh with IGD\n");

...

Isn’t that the disabled branch of `ifdef`?

yes, as C2_SELF_REFRESH_DISABLE = 0
