Change in coreboot[master]: cpu/intel/haswell: Clean up CPUID definitions
by Angel Pons (Code Review) April 14, 2026

April 14, 2026

( https://review.coreboot.org/c/coreboot/+/46915 ) Change subject: cpu/intel/haswell: Clean up CPUID definitions ...................................................................... cpu/intel/haswell: Clean up CPUID definitions The `mobile` suffix is misleading, since desktop CPUs share the same CPUIDs. Remove unused stepping IDs and add the full CPUIDs instead. Finally, add Broadwell CPUIDs in preparation for merging CPU code. Note that steppings for Haswell in various comments are incorrect. Tested with BUILD_TIMELESS=1, Asrock B85M Pro4 remains identical.

Patch Set 1: (1 comment) Patchset: PS1: This doesn't really look safe? Wouldn't the equivalent single-threaded version of `thread_run()` be to just run the passed function directly (otherwise it never runs at all)? But that's also not really safe in all cases because something in that code might wait for the main thread making forward progress, so I think the best option would still be to have the caller explicitly handle this difference. You should be able to do that with code like ``` if (ENV_SUPPORTS_COOP) { thread_run(...); } else { ...do the thing in the main thread... } ``` -- To view, visit https://review.coreboot.org/c/coreboot/+/91828?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: coreboot Gerrit-Branch: main Gerrit-Change-Id: Icd93e20231d88612ca399eed92581560856e2291 Gerrit-Change-Number: 91828 Gerrit-PatchSet: 1 Gerrit-Owner: Yidi Lin <yidilin(a)google.com> Gerrit-Reviewer: Chen-Tsung Hsieh <chentsung(a)google.com> Gerrit-Reviewer: Julius Werner <jwerner(a)chromium.org> Gerrit-Reviewer: Yu-Ping Wu <yupingso(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Chen-Tsung Hsieh <chentsung(a)google.com> Gerrit-Attention: Yidi Lin <yidilin(a)google.com> Gerrit-Comment-Date: Tue, 31 Mar 2026 21:57:05 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No

[S] Change in coreboot[main]: lib/thread: Add threshold-based yielding to optimize mdelay
by Julius Werner (Code Review) March 31, 2026

March 31, 2026

Attention is currently required from: Chen-Tsung Hsieh, Yidi Lin. Julius Werner has posted comments on this change by Yidi Lin. ( https://review.coreboot.org/c/coreboot/+/91827?usp=email ) Change subject: lib/thread: Add threshold-based yielding to optimize mdelay ...................................................................... Patch Set 1: (2 comments) Patchset: PS1: I'm concerned that we have many drivers that do `udelay(1)` in a loop to check for some hardware flag to turn on, potentially for a long time. We do want things to deschedule in that case. Rewriting all the drivers to use explicit `yield()` calls would be cumbersome and hard to keep working for future additions. Can you explain the issue you're seeing in more detail? Generally, I would expect the very simple context switching we do (no MMU impact, etc.) to take less than a millisecond. The timer queue framework should already be set up to correctly prioritize threads, so I honestly can't really think of a scenario where we are spending significant time on overhead while we have something that can actually make forward progress. (Of course, if you add UART output or something slow like that to the swtiching code, you totally change that calculus.) It looks like you're suggesting a 60 *milli*second threshold for Rauru, which sounds crazy huge. I feel like there may be some other issue there that makes things not work as effectively as intended, because from the theoretical side this shouldn't be such a problem. File src/lib/thread.c: https://review.coreboot.org/c/coreboot/+/91827/comment/8261267b_01934e0a?us… : PS1, Line 134: if (current->id != t->id) Is this something we want to keep in for production? Won't it trigger a lot in certain situations? (If you think it's useful maybe store a timestamp to rate-limit it when it fires more than a few times in 10ms, and move it to SPEW.)

[M] Change in coreboot[main]: arch/arm64: Add support for COOP_MULTITASKING

Attention is currently required from: Chen-Tsung Hsieh, Yidi Lin. Julius Werner has posted comments on this change by Yidi Lin. ( https://review.coreboot.org/c/coreboot/+/91826?usp=email ) Change subject: arch/arm64: Add support for COOP_MULTITASKING ...................................................................... Patch Set 1: (5 comments) File src/Kconfig: https://review.coreboot.org/c/coreboot/+/91826/comment/568ada6c_85fee684?us… : PS1, Line 818: ARCH_ARM64 > How about `COOP_MULTITASKING`? This breaks `checkstack()`. We'll probably need a more comprehensive solution here (something that distinguishes the main stack size, which is sometimes determined by Kconfig and sometimes by memlayout, and the other thread stack size which only matters when COOP is enabled).
