[PATCH v10 0/5] PCI: VF resizable BAR

[PATCH v10 0/5] PCI: VF resizable BAR

[Michał Winiarski]

Hi,

The series is now reviewed, and it looks like there's no further
feedback.
To limit it to PCI subsystem, I removed the last patch in the series, as
it contained changes in drm/xe driver (it can still be found in v9 for
reference, and I expect that this single patch will go through DRM tree
anyways).

v9 can be found here:
https://lore.kernel.org/linux-pci/20250527120637.665506-1-michal.winiarski@intel.com/

For regular BAR, drivers can use pci_resize_resource to resize it to the
desired size provided that it is supported by the hardware, which the
driver can query using pci_rebar_get_possible_sizes.
This series expands the API to work with IOV BAR as well.
It also adds the additional API for drivers to change the VF BAR size
without resizing the entire underlying reservation (within the original
resource boundary).

Thanks,
-Michał

- Reword kerneldoc for pci_iov_vf_bar_get_sizes (Bjorn)
- Reword commit message for VF BAR size check, extract the additional
  size check to separate conditional (Bjorn)

[PATCH v10 1/5] PCI/IOV: Restore VF resizable BAR state after reset

[Michał Winiarski]

Similar to regular resizable BAR, VF BAR can also be resized, e.g. by
the system firmware or the PCI subsystem itself.

The capability layout is the same as PCI_EXT_CAP_ID_REBAR.

Add the capability ID and restore it as a part of IOV state.

See PCIe r6.2, sec 7.8.7.

[PATCH v10 2/5] PCI: Add a helper to convert between VF BAR number and IOV resource

[Michał Winiarski]

There are multiple places where conversions between IOV resources and
corresponding VF BAR numbers are done.

Extract the logic to pci_resource_num_from_vf_bar() and
pci_resource_num_to_vf_bar() helpers.

[PATCH v10 3/5] PCI: Allow IOV resources to be resized in pci_resize_resource()

[Michał Winiarski]

Similar to regular resizable BAR, VF BAR can also be resized.

The capability layout is the same as PCI_EXT_CAP_ID_REBAR, which means
we can reuse most of the implementation, the only difference being
resource size calculation (which is multiplied by total VFs) and memory
decoding (which is controlled by a separate VF MSE field in SR-IOV cap).

Extend the pci_resize_resource() function to accept IOV resources.

See PCIe r6.2, sec 7.8.7.

[PATCH v10 4/5] PCI/IOV: Check that VF BAR fits within the reservation

[Michał Winiarski]

When the resource representing VF MMIO BAR reservation is created, its
size is always large enough to accommodate the BAR of all SR-IOV Virtual
Functions that can potentially be created (total VFs). If for whatever
reason it's not possible to accommodate all VFs - the resource is not
assigned and no VFs can be created.

An upcoming change will allow VF BAR size to be modified by drivers at
a later point in time, which means that the check for resource
assignment is no longer sufficient.

Add an additional check that verifies that VF BAR for all enabled VFs
fits within the underlying reservation resource.

[PATCH v10 5/5] PCI: Allow drivers to control VF BAR size

[Michał Winiarski]

Drivers could leverage the fact that the VF BAR MMIO reservation is
created for total number of VFs supported by the device by resizing the
BAR to larger size when smaller number of VFs is enabled.

Add a pci_iov_vf_bar_set_size() function to control the size and a
pci_iov_vf_bar_get_sizes() helper to get the VF BAR sizes that will
allow up to num_vfs to be successfully enabled with the current
underlying reservation size.

Hi Bjorn,

Can you consider applying this series?
Or do you still have some comments?
