KERNEL – 6.19-rc Pre-release Tests – VMware OK, NVIDIA Fails
Tested the December 10th version of the pre-6.19-rc code, and the latest VMware version 25.0.0 (25H2) compiles/loads OK, but NVIDIA (580.105.08 and 590.44.01) compiles fail with the same errors:

I was able to fix the in_irq error, by adding the define from /include/linux/preempt.h to the nv_time.h code, but was unable to fix the rest..
Obviously, there will be more changes to come before 6.19-rc is released, so there may be more errors to come..

Greetings!
Indeed: a lot seems to have changed for the upcoming 6.19 kernel.
According to this commit: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=70e0a80a1f3580ccf5bc1f34dbb433c67d9d8d00 “in_irq()” is an old alias for “in_hardirq()”.
NVIDIA: There are 2 places where this is used in the files common/inc/nv-time.h and nvidia/os-interface.c
In common/inc/nv-time.h:
– if (in_irq() && (us > NV_MAX_ISR_DELAY_US))
+ if (in_hardirq() && (us > NV_MAX_ISR_DELAY_US))
And in nvidia/os-interface.c:
– return (in_irq());
+ return (in_hardirq());
And like you I couldn’t resolve the other errors (yet?).
And there might be more to come, unfortunately…
