Sun, 03 Nov 2024 15:51:53 +0100

riscv: Add qspinlock supportIn order to produce a generic kernel, a user can selectCONFIG_COMBO_SPINLOCKS which will fallback at runtime to the ticketspinlock implementation if Zabha or Ziccrse are not present.Note that we can't use alternatives here because the discovery ofextensions is done too late and we need to start with the qspinlockimplementation because the ticket spinlock implementation would pollutethe spinlock value, so let's use static keys.This is largely based on Guo's work and Leonardo reviews at [1].Link: https://lore.kernel.org/linux-riscv/20231225125847.2778638-1-guoren@kernel.org/ [1]Signed-off-by: Guo Ren Signed-off-by: Alexandre Ghiti Reviewed-by: Andrea Parri Link: https://lore.kernel.org/r/20241103145153.105097-14-alexghiti@rivosinc.comSigned-off-by: Palmer Dabbelt List of files: /linux/include/asm-generic/ticket_spinlock.h
