[Qemu-devel] [PATCH v7 0/4] Generic PCIE-PCI Bridge
Posted by Aleksandr Bezzubikov 6 years, 7 months ago
This series introduces a new device - Generic PCI Express to PCI bridge,
and also makes all necessary changes to enable hotplug of the bridge itself
and any device into the bridge.

Changes v6->v7:
Change IO/MEM/PREF reservation properties type to SIZE.

Changes v5->v6:
1. Fix indentation in the cap creation function (addresses Marcel's comment)
2. Simplify capability pref_mem_* fields assignment (addresses Marcel's comment)
3. Documentation fixes:
	- fix mutually exclusive fields definition (addresses Laszlo's comment)
	- fix pcie-pci-bridge usage example (addresses Marcel's comment)

Changes v4->v5:
1. Change PCIE-PCI Bridge license (addresses Marcel's comment)
2. The capability layout changes (adress Laszlo' comments): 
    - separate pref_mem into pref_mem_32 and pref_mem_64 fields (SeaBIOS side has the same changes)
    - accordingly change the Generic Root Port's properties
3. Do not add the capability to the root port if no valid values are provided (adresses Michael's comment)
4. Rename the capability type to 'RESOURCE_RESERVE' (addresses Marcel's comment)
5. Remove shpc_present check function (addresses Marcel's comment)
6. Fix the 4th patch message (adresses Michael's comment)
7. Patch for SHPC enabling in _OSC method has been already merged

Changes v3->v4:
1. PCIE-PCI Bridge device: "msi_enable"->"msi", "shpc"->"shpc_bar", remove local_err,
   make "msi" property OnOffAuto, shpc_present() is still here 
   to avoid SHPC_VMSTATE refactoring (address Marcel's comments). 
2. Change QEMU PCI capability layout (SeaBIOS side has the same changes):
  - change reservation fields types: bus_res - uint32_t, others - uint64_t
  - rename 'non_pref' and 'pref' fields
  - interpret -1 value as 'ignore'
3. Use parent_realize in Generic PCI Express Root Port properly.
4. Fix documentation: fully replace the DMI-PCI bridge references with the new PCIE-PCI bridge,
"PCIE"->"PCI Express", small mistakes and typos - address Laszlo's and Marcel's comments.
5. Rename QEMU PCI cap creation fucntion - addresses Marcel's comment.

Changes v2->v3:
(0). 'do_not_use' capability field flag is still _not_ in here since we haven't come to consesus on it yet.
1. Merge commits 5 (bus_reserve property creation) and 6 (property usage) together - addresses Michael's comment.
2. Add 'bus_reserve' property and QEMU PCI capability only to Generic PCIE Root Port - addresses Michael's and Marcel's comments.
3. Change 'bus_reserve' property's default value to 0 - addresses Michael's comment.
4. Rename QEMU bridge-specific PCI capability creation function - addresses Michael's comment.
5. Init the whole QEMU PCI capability with zeroes - addresses Michael's and Laszlo's comments.
6. Change QEMU PCI capability layout (SeaBIOS side has the same changes)
  - add 'type' field to distinguish multiple 
    RedHat-specific capabilities - addresses Michael's comment
  - do not mimiс PCI Config space register layout, but use mutually exclusive differently
    sized fields for IO and prefetchable memory limits - addresses Laszlo's comment
7. Correct error handling in PCIE-PCI bridge realize function.
8. Replace a '2' constant with PCI_CAP_FLAGS in the capability creation function - addresses Michael's comment.
9. Remove a comment on _OSC which isn't correct anymore - address Marcel's comment.
10. Add documentation for the Generic PCIE-PCI Bridge and QEMU PCI capability - addresses Michael's comment.

Changes v1->v2:
1. Enable SHPC for the bridge.
2. Enable SHPC support for the Q35 machine (ACPI stuff).
3. Introduce PCI capability to help firmware on the system init.
   This allows the bridge to be hotpluggable. Now it's supported 
   only for pcie-root-port. Now it's supposed to used with 
   SeaBIOS only, look at the SeaBIOS corresponding series
   "Allow RedHat PCI bridges reserve more buses than necessary during init".

Aleksandr Bezzubikov (4):
  hw/pci: introduce pcie-pci-bridge device
  hw/pci: introduce bridge-only vendor-specific capability to provide
    some hints to firmware
  hw/pci: add QEMU-specific PCI capability to the Generic PCI Express
    Root Port
  docs: update documentation considering PCIE-PCI bridge

Hi,

Series
    Tested-by: Marcel Apfelbaum <marcel@redhat.com>
(focused on changes from v6)


Michael, will Alecsandr need to re-send it after freeze?
I am asking because the GSOC project is ending in a week or so.


Thanks,
Marcel
