[PATCH 0/9] hw/ide/ahci: Housekeeping

[Philippe Mathieu-Daudé]

- Split 'ahci.h' as sysbus / pci
- Inline ahci_get_num_ports()
- Directly use AHCIState::ports instead of SysbusAHCIState::num_ports

Philippe Mathieu-Daudé (9):
  hw/i386/q35: Use DEVICE() cast macro with PCIDevice object
  hw/ide/ahci: Expose AHCIPCIState structure
  hw/ide/ahci: Rename AHCI PCI function as 'pdev'
  hw/ide/ahci: Inline ahci_get_num_ports()
  hw/ide/ahci: Pass AHCI context to ahci_ide_create_devs()
  hw/ide/ahci: Convert AHCIState::ports to unsigned
  hw/ide/ahci: Do not pass 'ports' argument to ahci_realize()
  hw/ide/ahci: Remove SysbusAHCIState::num_ports field
  hw/ide/ahci: Move SysBus definitions to 'ahci-sysbus.h'

[PATCH 1/9] hw/i386/q35: Use DEVICE() cast macro with PCIDevice object

[Philippe Mathieu-Daudé]

QDev API provides the DEVICE() macro to access the
'qdev' parent field of the PCIDevice structure.

[PATCH 2/9] hw/ide/ahci: Expose AHCIPCIState structure

[Philippe Mathieu-Daudé]

In order to be able to QOM-embed a structure, we need
its full definition. Move it from "ahci_internal.h"
to the new "hw/ide/ahci-pci.h" header.

As far as it goes.  But it certainly highlights that

ports is always a constant.  Or perhaps that's only from this PCI usage?

I'm just moving code around :)

I'm not sure about this assert, but TBH I consider ide_drive_get()
as legacy API (pre -blockdev, only 7 uses in the tree, half from old
boards).

I'll let that constant cleanup for later.

[PATCH 5/9] hw/ide/ahci: Pass AHCI context to ahci_ide_create_devs()

[Philippe Mathieu-Daudé]

Since ahci_ide_create_devs() is not PCI specific, pass
it an AHCIState argument instead of PCIDevice.

[PATCH 6/9] hw/ide/ahci: Convert AHCIState::ports to unsigned

[Philippe Mathieu-Daudé]

AHCIState::ports should be unsigned. Besides, we never
check it for negative value. It is unlikely it was ever
used with more than INT32_MAX ports, so it is safe to
convert it to unsigned.
