Hi,
Resurrecting an old series [1], now that we have an in-tree user for it.
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
Similar to regular resizable BAR, VF BAR can also be resized, e.g. by
the system firmware, or the PCI subsystem itself.
Add the capability ID and restore it as a part of IOV state.
See PCIe r4.0, sec 9.3.7.4.

There are multiple places where special handling is required for IOV
resources.
Extract it to a helper and drop a few ifdefs.

Opt into extending the VF BAR.
LMEM is partitioned between multiple VFs, and we expect that the more
VFs we have, the less LMEM is assigned to each VF.
This means that we can achieve full LMEM BAR access without the need to
attempt full VF LMEM BAR resize via pci_resize_resource().

VF MMIO resource reservation, either created by system firmware and
inherited by Linux PCI subsystem or created by the subsystem itself,
contains enough space to fit the BAR of all SR-IOV Virtual Functions
that can potentially be created (total VFs supported by the device).
This can be leveraged wh
Similar to regular resizable BAR, VF BAR can also be resized.
The structures are very similar, which means we can reuse most of the
implementation. See PCIe r4.0, sec 9.3.7.4.

drm_hdmi_avi_infoframe_from_display_mode() called from
it66121_bridge_mode_set() already calls hdmi_avi_infoframe_init() to
initialize an HDMI AVI infoframe. So, drop the redundant
hdmi_avi_infoframe_init() function call from it66121_bridge_mode_set().

The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
arithmetic and then assigned to and operated upon using a 64 bit unsigned
integer. In the case where the shift is 32 or more this can lead to an
overflow. Avoid this by shifting using the BIT_ULL macro instead.

VKMS currently supports only one CRTC, so it make no sense to have this

There is no need to manually set a crtc mask on primary and cursor plane
