smp: Mark smp_prepare_boot_cpu() __init

2024-09-08T14:01:10Z

smp_prepare_boot_cpu() is only called during boot, hence mark it as __init. Signed-off-by: Bibo Mao Signed-off-by: Thomas Gleixner Reviewed-by: Huacai Chen Link: https://lore.kernel.org/all/20240907082720.452148-1-maobibo@loongson.cn

Revert "MIPS: csrc-r4k: Apply verification clocksource flags"

2024-08-25T22:26:30Z

This reverts commit 7190401fc56fb5f02ee3d04476778ab000bbaf32. Verifying the clock source sometimes deems the MIPS clock to be unstable, at least in qemu. clocksource: timekeeping watchdog on CPU0: Marking clocksource 'MIPS' as unstable because the skew is too large: clocksource: 'jiffies' wd_nsec: 500000000 wd_now: ffff8bde wd_last: ffff8bac mask: ffffffff clocksource: 'MIPS' cs_nsec: 940634468 cs_now: 310181c4 cs_last: 28090a09 mask: ffffffff clocksource: Clocksource 'MIPS' skewed 440634468 ns (440 ms) over watchdog 'jiffies' interval of 500000000 ns (500 ms) clocksource: 'MIPS' is current clocksource. If this happens, network interfaces fail to come online. Signed-off-by: Guenter Roeck

MIPS: cevt-r4k: Don't call get_c0_compare_int if timer irq is installed

2024-08-20T08:36:52Z

This avoids warning: [ 0.118053] BUG: sleeping function called from invalid context at kernel/locking/mutex.c:283 Caused by get_c0_compare_int on secondary CPU. We also skipped saving IRQ number to struct clock_event_device *cd as it's never used by clockevent core, as per comments it's only meant for "non CPU local devices".

MIPS: Loongson64: Set timer mode in cpu-probe

2024-08-08T16:17:43Z

Loongson64 C and G processors have EXTIMER feature which is conflicting with CP0 counter. Although the processor resets in EXTIMER disabled & INTIMER enabled mode, which is compatible with MIPS CP0 compare, firmware may attempt to enable EXTIMER and interfere CP0 compare. Set timer mode back to MIPS compatible mode to fix booting on systems with such firmware before we have an actual driver for EXTIMER.

MIPS: SMP-CPS: Fix address for GCR_ACCESS register for CM3 and later

2024-07-23T07:30:13Z

When the CM block migrated from CM2.5 to CM3.0, the address offset for the Global CSR Access Privilege register was modified. We saw this in the "MIPS64 I6500 Multiprocessing System Programmer's Guide," it is stated that "the Global CSR Access Privilege register is located at offset 0x0120" in section 5.4. It is at least the same for I6400. This fix allows to use the VP cores in SMP mode if the reset values were modified by the bootloader. Based on the work of Vladimir Kondratiev and the feedback from Jiaxun Yang .
