* ukleinek wonders about drivers/irqchip/irq-riscv-imsic-early.c:52:9: error: too many arguments to function ‘riscv_ipi_set_virq_range’ in linus/master
<conchuod> linus' fault ;)
<conchuod> He was told about it in the PR

<ukleinek> conchuod: ah, Linus didn't take the suggested merge resolution from https://lore.kernel.org/all/mhng-e73e59bf-92fc-4122-9f9e-a329d20eba55@palmer-ri-x1c9/ it seems.
<conchuod> Yeah. Palmer sent a patch for it: 20240522184953.28531-3-palmer@rivosinc.com

<broonie> ardb: Did you manage to reproduce that FP issue or was the fix done purely from inspection?
<ardb> broonie: no i managed to reproduce it
<ardb> with the fio test running concurrently with a couple of instances of fpsimd-test
<ardb> that way, it reproduced within a minute for me in a VM running on a M2 mac
<broonie> Ah, cool. What hardware were you using? I never managed to get it to trigger.
<broonie> Right, thanks.
<ardb> i imagine it would be rather easy to reproduce by adding a schedule() in kernel_neon_end()
<broonie> Yes, probably.
<ardb> however, the kernel mode failure is not as easy to hit as the usermode one
<ardb> i.e., 19 out of 20 times, it would be fpsimd-test failing not fio
<ardb> the kernel side only fails because we do the cpu binding thing
<ardb> which may result in fpsimd_save_user_state() writing its state to the kernel mode buffer
<broonie> Right, there will have been some unnoticed userspace corruption going on in other cases but fpsimd-test aggressively going out and looking for problems made it more obvious.
<broonie> dmart is probably right that we should do the kernel mode binding earlier.

<dmart> broonie: Do you think there is an actual bug there? It depends on what kinds of interrupts / preemption can happen, but I hadn't figured it out.
<broonie> dmart: I can't think of a specific issue that currently exists but it feels like even if one doesn't exist now one will at some future point.

<dmart> broonie: See what ardb thinks, I guess. I'd vote for moving the _bind_to_cpu() to the sched-in path unless there's a clear reason why not...
