Commit Message

Niklas Schnelle Dec. 27, 2021, 4:42 p.m. UTC 
Introduce a new LEGACY_PCI Kconfig option which gates support for legacy
PCI devices including those attached to a PCI-to-PCI Express bridge and
PCI Express devices using legacy I/O spaces. Note that this is different
from non PCI uses of I/O ports such as by ACPI.

Add dependencies on LEGACY_PCI for all PCI drivers which only target
legacy PCI devices and ifdef legacy PCI specific functions in ata
handling.

Hmm, I might be missing something here but that sounds a lot like the
HAS_IOPORT option added in patch 02.

We add both LEGACY_PCI and HAS_IOPORT to differentiate between two
cases. HAS_IOPORT is for PC-style devices that are not on a PCI card
while LEGACY_PCI is for PCI drivers that require port I/O. This
includes pre-PCIe devices as well as PCIe devices which require
features like I/O spaces. The "legacy" naming is comes from the PCIe
spec which in section 2.1.1.2 says "PCI Express supports I/O Space for
compatibility with legacy devices which require their use. Future
revisions of this specification may deprecate the use of I/O Space."

These two separate config options allow us to compile without support
for these legacy PCI devices even on a system where inb()/outb() and
friends are required for some PC style devices and for example ACPI.

Makes sense, if these get more legacy over time we can always change
the default. This would also mean we don't need to change defconfigs
that include legacy PCI devices.

Playing around with the reordering I think it might make sense to
introduce HAS_IOPORT in patch 01, then LEGACY_PCI in patch 02 and then
add dependencies for both on a per subsystem basis. I think it would be
overkill to have two series of per subsystem patches.

That is not intentional. The dependencies are certainly not perfect yet
which is one of the reasons this is still an RFC. I hope getting these
right will be a lot easier if we do both LEGACY_PCI and HAS_IOPORT
dependency selection on a per subsystem basis.

As far as I can see this one actually uses a hardcoded I/O port numbers
and googling it looks like it's an on-board device on the UDOO x86
board. I guess that should indeed just be
"depends on PCI && DMI && HAS_IOPORT".

Ok, I think we definitely need to work on getting the dependencies
right. I do think we agree that once done correctly there is value in
such an option independent of HAS_IOPORT only gating inb() etc uses.
