ahci: Restrict NVMe redirection by BAR size 2026-02-24T21:43:36+00:00 Alexander Motin mav@FreeBSD.org 2026-02-09T19:23:26+00:00 aabd5243fb97979d33a7eece4f7cca18ffd82a95 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.
