Hi folks,
For some reason, gfx wont init on Sandybridge P8H61-M PRO with i5-2500T on coreboot 4.9
Following a recommendation from Icon in coreboot IRC chat, the following debug was added to check the value of reg16
diff ../core2/src/northbridge/intel/sandybridge/early_init.c ./src/northbridge/intel/sandybridge/early_init.c 86c86 < ---
102a103
printk(BIOS_DEBUG, "%lx\n", (long)reg16);
The serial log shows
coreboot-4.9-1050-gebd8a4f90c-dirty Sat Mar 16 16:22:16 UTC 2019 romstage starting (log level: 7)... Setting up static southbridge registers... done. Disabling Watchdog reboot... done. Setting up static northbridge registers... done. ffff Graphics not supported by this CPU/chipset. Back from sandybridge_early_initialization()
lspci with manufacturers BIOS and linux shows the display controller at 00:02.0 as 8086:0102 . There are no other display controllers connected to the system.
Build log, defconfig, flash log and boot log are attached
Any pointers are greatly appreciated!
