Change in coreboot[master]: nb/intel/sandybridge: Improve channel disable logic
by Angel Pons (Code Review) April 11, 2024

April 11, 2024

Angel Pons has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/45500 ) Change subject: nb/intel/sandybridge: Improve channel disable logic ...................................................................... nb/intel/sandybridge: Improve channel disable logic Do not consider the failed channel's SPDs in emergency mode. Also, force a full training if not resuming from S3 and the saved data indicates a channel has failed. Special care needs to be taken as the selected memory frequency could be raised after a channel has been disabled. Tested on Asus P8Z77-V LX2, with a good DIMM on channel 0 and a bad DIMM on channel 1. The failing channel causes errors when discovering timB, and emergency mode raminit for the other channel is good enough to boot. With this commit: a. Regular boots always result in full training. b. The board still boots, as emergency raminit trained the good DIMM. c. S3 resume still works in all tested configurations. d. If pretending the bad DIMM is slower: 1. The MPLL gets locked at the slow frequency of the bad DIMM. 2. The first raminit attempt still fails miserably on the bad DIMM. 3. Emergency mode uses the frequency the MPLL is locked at. 4. The board boots with the good DIMM running at the slow frequency. With good DIMMs on both channels, everything works the same as before.

Change in coreboot[master]: arch,toolchain,xcompile: Use GCC as linker
by Jacob Garber (Code Review) April 4, 2024

April 4, 2024

Jacob Garber has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/40811 ) Change subject: arch,toolchain,xcompile: Use GCC as linker ...................................................................... arch,toolchain,xcompile: Use GCC as linker Code generation when using LTO is not done until after linking, so the compiler must be invoked at all linking stages instead of the linker. Replace $(LD) with GCC, and prefix all linker-specific flags with -Wl so they will be passed to the linker.

Change in coreboot[master]: WIP: riscv/mb/qemu: fix DRAM probing
by Philipp Hug (Code Review) March 4, 2024

March 4, 2024

Philipp Hug has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/36486 ) Change subject: WIP: riscv/mb/qemu: fix DRAM probing ......................................................................

Change in coreboot[master]: [TEST] Add support for link time optimization
by Jacob Garber (Code Review) Feb. 22, 2024

Feb. 22, 2024

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.
