Hi,
I would like to renew the effort on Host Devices for Cockpit [1].
To move forward, let's implement it step by step while opening brand new PR
picking just a subset of the already implemented functionality [1] while
adjusted to generally acceptable form.
Initial implementation would meet:
- PCI support only
- initially read-only: just the List of devices by their Class (according
to [2])
- example: by Audio device, Ethernet Controller, etc
- data source: sysfs
- make use of backward-compatible lspci for data preprocessing (especially
manipulation with HW database)
- monitor for changes by listening kernel uevents
Follow-ups will lead to [3] scope:
- for pci, active actions are allowed for selected device classes, one PR
per each:
- (un)bind VFIO driver
- configure SR-IOV network cards
- vGPU configuration
- additional view by Driver
- What devices is the driver bound to?
- additional view by IOMMU Groups
- For server fine-tuning, what devices are within single IOMMU Group?
- support for other buses, i.e. USB or SCSI
- their views are independent on each other due to fundamental differences
Please let me know your thoughts.
Thanks,
Marek
