Jun 10, 2024 · Re: [PATCH] x86: add 'runtime constant' infrastructure. > So I would also strongly suggest that we make the code fault if it is executed unpatched if there is no fallback. valid address before patching. Doing it in general is actually very very painful. Feel free to try -.
Jun 10, 2024 · And those kinds of runtime constant addresses would always. be the full 64-bit - I don't think 32-bit is interesting enough to. spend any effort on. (Yes, you can get 32-bit rip-address constants if you start doing. things like conditional link addresses, but that's what things like. static_call() is for - not this runtime constant code) Linus.

Jun 11, 2024 · fixed first" argument doesn't really work well either (and _that_ has. been discussed for over a decade at various maintainer summits). Maybe the people who have concerns about this can work on those. concerns when it's in-tree.

Jun 11, 2024 · Phoronix: Linus Torvalds Throws Down The Hammer: Extensible Scheduler "sched_ext" In Linux 6.11 The extensible scheduler "sched_ext" code has proven quite versatile for opening up better Linux gaming performance, more quickly prototyping new scheduler changes, Ubuntu/Canonical has been evaluating it for
Jun 10, 2024 · And while arm64 can take a 32-bit input register and output a 64-bit. output, on x86-64 the input and output registers are the same, and you. cannot tell the compiler that the upper 32 bits don't matter on input. to the asm. End result: you actually want to keep the input to the constant shift.
