mfi timeouts

[Jan Mikkelsen]

Hi,

Sorry about being unclear. They all failed in the same way.

So, these combinations have continuous timeout errors and fail to completely boot:

  Plain 9.0-RC1

  9-stable with 1.62 of mfi.c

  9-stable with www.freebsd.org/~jhb/patches/mfi.patch, pci_alloc_msi
  instead of pci_alloc_msix and hw.mfi.msix=0

This boots, but gets "mfi0: Cannot allocate interrupt" and there are no /dev/mfi* devices:

  9-stable with www.freebsd.org/~jhb/patches/mfi.patch and hw.mfi.msix=1

This seems to work, but I have not put any load on it yet:

  9-stable with www.freebsd.org/~jhb/patches/mfi.patch, pci_alloc_msi
  instead of pci_alloc_msix and hw.mfi.msix=1


I see you have a new patch, www.freebsd.org/~jhb/patches/mfi_msi.patch. This patch doesn't seem to include the dummy read from your earlier patch, or the one in 1.62 of mfi.c. I assume I need to apply the 1.62 mfi.c diff to by 9-stable sources as well. Is that correct?

Will test out the new patch.

Thanks,

Jan Mikkelsen
