2024-01-16riscv: fpu: drop SR_SD bit checkingAndy Chiu1-2/+1
SR_SD summarizes the dirty status of FS/VS/XS. However, the current code structure does not fully utilize it because each extension specific code is divided into an individual segment. So remove the SR_SD check for now.

2024-01-16riscv: lib: vectorize copy_to_user/copy_from_userAndy Chiu6-1/+125
This patch utilizes Vector to perform copy_to_user/copy_from_user. If Vector is available and the size of copy is large enough for Vector to perform better than scalar, then direct the kernel to do Vector copies for userspace. Though the best programming practice for users is to reduce the copy, this provides a faster variant when copies are inevitable. The optimal size for using Vector, copy_to_user_thres, is only a heuristic for now. We can add DT parsing if people feel the need of customizing it. The exception fixup code of the __asm_vector_usercopy must fallback to the scalar one because accessing user pages might fault, and must be sleepable. Current kernel-mode Vector does not allow tasks to be preemptible, so we must disactivate Vector and perform a scalar fallback in such case. The original implementation of Vector operations comes from https://github.com/sifive/sifive-libc, which we agree to contribute to Linux kernel.

2024-01-16riscv: sched: defer restoring Vector context for userAndy Chiu8-5/+41
User will use its Vector registers only after the kernel really returns to the userspace. So we can delay restoring Vector registers as long as we are still running in kernel mode. So, add a thread flag to indicates the need of restoring Vector and do the restore at the last arch-specific exit-to-user hook. This save the context restoring cost when we switch over multiple processes that run V in kernel mode. For example, if the kernel performs a context swicth from A->B->C, and returns to C's userspace, then there is no need to restore B's V-register. Besides, this also prevents us from repeatedly restoring V context when executing kernel-mode Vector multiple times. The cost of this is that we must disable preemption and mark vector as busy during vstate_{save,restore}. Because then the V context will not get restored back immediately when a trap-causing context switch happens in the middle of vstate_{save,restore}.

2024-01-16riscv: vector: make Vector always available for softirq contextAndy Chiu3-4/+19
The goal of this patch is to provide full support of Vector in kernel softirq context. So that some of the crypto alogrithms won't need scalar fallbacks. By disabling bottom halves in active kernel-mode Vector, softirq will not be able to nest on top of any kernel-mode Vector. So, softirq context is able to use Vector whenever it runs. After this patch, Vector context cannot start with irqs disabled. Otherwise local_bh_enable() may run in a wrong context. Disabling bh is not enough for RT-kernel to prevent preeemption. So we must disable preemption, which also implies disabling bh on RT.

2024-01-16sched/fair: Fix frequency selection for non-invariant caseVincent Guittot1-1/+5
Linus reported a ~50% performance regression on single-threaded workloads on his AMD Ryzen system, and bisected it to: 9c0b4bb7f630 ("sched/cpufreq: Rework schedutil governor performance estimation") When frequency invariance is not enabled, get_capacity_ref_freq(policy) is supposed to return the current frequency and the performance margin applied by map_util_perf(), enabling the utilization to go above the maximum compute capacity and to select a higher frequency than the current one. After the changes in 9c0b4bb7f630, the performance margin was applied earlier in the path to take into account utilization clampings and we couldn't get a utilization higher than the maximum compute capacity, and the CPU remained 'stuck' at lower frequencies. To fix this, we must use a frequency above the current frequency to get a chance to select a higher OPP when the current one becomes fully used. Apply the same margin and return a frequency 25% higher than the current one in order to switch to the next OPP before we fully use the CPU at the current one.

2024-01-15spinlock: Fix failing build for PREEMPT_RTLeonardo Bras1-6/+6
Since 1d71b30e1f85 ("sched.h: Move (spin|rwlock)_needbreak() to spinlock.h") build fails for PREEMPT_RT, since there is no definition available of either spin_needbreak() and rwlock_needbreak(). Since it was moved on the mentioned commit, it was placed inside a !PREEMPT_RT part of the code, making it out of reach for an RT kernel. Fix this by moving code it a few lines down so it can be reached by an RT build, where it can also make use of the *_is_contended() definition added by the spinlock_rt.h.
