[Qemu-devel] [PATCH 0/8] Kconfig: Clean up the PIIX southbridge devices

[Qemu-devel] [PATCH 0/8] Kconfig: Clean up the PIIX southbridge devices

[Philippe Mathieu-Daudé]

Hi,

This series is a cleanup for the PIIX/PIIX3/PIIX4 devices.

The isapc machine split isn't clean because while designed
on a PIIX3, our model uses ACPI features from the PIIX4.

The i440fx cleanup is left for the the next development cycle.

This series is a prerequisite for the MIPS Malta port to Kconfig.

Please review.

Regards,

Phil.

Please ignore this patch in this series, I incorrectly reordered it here
while rebasing, but it doesn't work without the next series "Kconfig:
Cleanup the ICH9 device". As it there is a circular dependency with
PC_ACPI.

[Qemu-devel] [PATCH 2/8] hw/input: Add 8042 PS/2 Keyboard Controller to Kconfig

[Philippe Mathieu-Daudé]

The Intel 8042 chipset also includes some functions unrelated to
the keyboard, such the A20-Gate.

I fail to see why you need this config switch. There is a "select I8042"
in a later patch, but that's it - you never use this switch to decide
anything (like including a file in the Makefiles or toggle other
switches), so this seems to be just a defunc switch to me. Or do I miss
something?

The PIIX3 emulates a 8042 when the USB Legacy Support is enabled.

Oh now I see, I first understood the hw/input/pckbd.c file was
modeling the 8042 and other things, but no, it is simply it.

So please disregard this patch, I'll respin renaming PCKBD -> I8042.

Thanks!

Phil.

[Qemu-devel] [PATCH 3/8] hw/southbridge: Add the PIIX chipset to Kconfig

[Philippe Mathieu-Daudé]

The PIIX (Intel 82371FB) is a bridge between PCI <-> ISA.

It contains:
 - IDE interface (PIO and burst transfers)
 - one 82c54 timer (and speaker tone output)
 - two 82c59 interrupts controllers
 - two 8237 DMA controllers
 - Power Management (programmable SMI)
 - NMI

[Qemu-devel] [PATCH 4/8] hw/southbridge: Add the PIIX3 chipset to Kconfig

[Philippe Mathieu-Daudé]

The PIIX3 (Intel 82371SB) is a bridge between PCI <-> ISA.

It is an exhanced PIIX, thus contains the same features.
It also contains:
 - separate Master/Slave IDE mode
 - compliant to PCI rev 2.1 specifications
 - IOAPIC
 - USB UHCI (2 ports)
 - USB Legacy Support (emulated devices):
   - 8042 Keyboard Controller
   - A20-Gate

[Philippe Mathieu-Daudé]

The PIIX4 (Intel 82371AB) is a bridge between PCI <-> ISA.

It is an exhanced PIIX3, thus contains the same features.
It also contains:
 - Power Management (ACPI rev 1.0)
 - IDE UDMA/33
 - SMBus interface (host and slave)
 - RTC

Since the default-configs/mips-softmmu-common.mak is not yet ported
to the Kconfig format, we have to select this variable there (used
by the MIPS Malta machine).
