Hi there,
I managed to get a working version of the pci device reservation for
the old pci bus manager to avoid races between native drivers and
OSS...
http://revolf.free.fr/beos/patches/pci_reserve_try4.diff.txt
I'd bump the version on B_PCI_MODULE_NAME to 1.1 since R5 didn't have
those calls (nor pci_find_capability actually), but it's not strictly
needed.
Didn't try with OSS yet, but calling pci_reserve_device() from itself
with other args fails as expected, so it should work.
As an example the support for es1370 is in the diff, it's quite minimal
so it should be easy to add to other drivers and OSS, and have it ready
for the alpha.
Comments ?
François.
