ahci: Restrict NVMe redirection by BAR size

2026-02-09T19:23:26+00:00

Attempts to access vendor-specific registers on emulator of older
Intel hardware was reported to confuse one.  Since the redirection
obviously require BAR size bigger than normal 2KB of AHCI, add
the condition, similar to what Linux is doing.

2025-12-09T20:00:06+00:00

The wrapper functions such as bus_alloc_resource_any() still support
passing the rid by value or pointer, but the underlying implementation
now passes by value.

ahci: Don't fail attach if the MSI-X BARs cannot be allocated

2025-10-06T17:56:47+00:00

If the MSI-X table and/or PBA live in separate BAR(s) and those BAR(s)
cannot be allocated, fall back to using MSI or INTx instead of failing
attach.

machine/stdarg.h -> sys/stdarg.h

2025-06-11T16:39:02+00:00

Switch to using sys/stdarg.h for va_list type and va_* builtins.

Make an attempt to insert the include in a sensible place.  Where
style(9) was followed this is easy, where it was ignored, aim for the
first block of sys/*.h headers and don't get too fussy or try to fix
other style bugs.
