Change in coreboot[master]: [TEST] Add support for link time optimization
by Jacob Garber (Code Review) 22 Feb '24

Jacob Garber has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/38989 ) Change subject: [TEST] Add support for link time optimization ...................................................................... [TEST] Add support for link time optimization - Code generation is not done until after linking, so the compiler must be invoked at all linking stages instead of the linker. As a consequence all linker arguments must be prefixed with -Wl. - Partial linking is not supported. Instead, object files are collected into thin archives that are linked instead. - The dead_code() macro causes linking errors, since dead functions aren't optimized out until after linking has begun. This macro could be replaced with the preprocessor if necessary, or just disabled for LTO builds. - Wrapping libgcc functions causes a symbol mismatch when using LTO. Wrapping these functions was originally done to support alternate regparam values, though AFAICT this isn't used anywhere. Using LTO leads to a ~10% decrease in stage size for QEMU and ~18% for the Thinkpad T500, and both targets boot successfully.

Change in coreboot[master]: nb/intel/sandybridge: Refine power-down mode logic
by Angel Pons (Code Review) 04 Jan '24

04 Jan '24

Angel Pons has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/47746 ) Change subject: nb/intel/sandybridge: Refine power-down mode logic ...................................................................... nb/intel/sandybridge: Refine power-down mode logic When memory is running at fast frequencies, power-down modes can lessen system stability. Check tXP and tXPDLL values and use safer power down modes if their values are high. Do not use APD with DLL-off on mobile: vendor firmware does not use it, and it can influence system stability.
