[Qemu-devel] [PATCH 00/19] Declare device little or big endian

[Tony Nguyen]

This series is an attempt to re-declare devices with DEVICE_NATIVE_ENDIAN as
DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN.

This clean up was split out from an earlier series which collapsed byte swaps
along the I/O path.

Approach this in two steps.

1. Naively. For each device declared with DEVICE_NATIVE_ENDIAN, find the set of
targets from the set of target/hw/*/device.o.

If the set of targets are all little or all big endian, re-declare
as DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN respectively.

2. Manually. Inspect with heuristics (thanks Paolo):
- if not used, re-declare as DEVICE_HOST_ENDIAN.
- if max/min size=1, re-declare as DEVICE_HOST_ENDIAN.
- if just a bit bucket, re-declare as DEVICE_HOST_ENDIAN
- if PCI, re-declare as DEVICE_LITTLE_ENDIAN.
- if for {ARM|unicore32} only, re-declare as DEVICE_LITTLE_ENDIAN.
- if for SPARC only, re-declare as DEVICE_BIG_ENDIAN.

Likely still not %100 correct, but I think more than before.

Since RFC:
- Applied Paolo's heuristics

[Qemu-devel] [PATCH 04/19] hw/core: Declare device little or big endian

[Tony Nguyen]

For each device declared with DEVICE_NATIVE_ENDIAN, find the set of
targets from the set of target/hw/*/device.o.

If the set of targets are all little or all big endian, re-declare
as DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN respectively.

Then, on inspection:
- if ununsed, re-declare as DEVICE_HOST_ENDIAN.
- if max/min size=1, re-declare as DEVICE_HOST_ENDIAN.
- if just a bit bucket, re-delcare as DEVICE_HOST_ENDIAN
- if PCI, re-declare as DEVICE_LITTLE_ENDIAN.
- if for {ARM|unicore32} only, re-declare as DEVICE_LITTLE_ENDIAN.
- if for SPARC only, re-declare as DEVICE_BIG_ENDIAN.

[Qemu-devel] [PATCH 11/19] hw/ipack: Declare device little or big endian

[Tony Nguyen]

For each device declared with DEVICE_NATIVE_ENDIAN, find the set of
targets from the set of target/hw/*/device.o.

If the set of targets are all little or all big endian, re-declare
as DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN respectively.

Then, on inspection:
- if ununsed, re-declare as DEVICE_HOST_ENDIAN.
- if max/min size=1, re-declare as DEVICE_HOST_ENDIAN.
- if just a bit bucket, re-delcare as DEVICE_HOST_ENDIAN
- if PCI, re-declare as DEVICE_LITTLE_ENDIAN.
- if for {ARM|unicore32} only, re-declare as DEVICE_LITTLE_ENDIAN.
- if for SPARC only, re-declare as DEVICE_BIG_ENDIAN.

[Qemu-devel] [PATCH 15/19] hw/pci-host: Declare device little or big endian

[Tony Nguyen]

For each device declared with DEVICE_NATIVE_ENDIAN, find the set of
targets from the set of target/hw/*/device.o.

If the set of targets are all little or all big endian, re-declare
as DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN respectively.

Then, on inspection:
- if not used, re-declare as DEVICE_HOST_ENDIAN.
- if max/min size=1, re-declare as DEVICE_HOST_ENDIAN.
- if just a bit bucket, re-declare as DEVICE_HOST_ENDIAN
- if PCI, re-declare as DEVICE_LITTLE_ENDIAN.
- if for {ARM|unicore32} only, re-declare as DEVICE_LITTLE_ENDIAN.
- if for SPARC only, re-declare as DEVICE_BIG_ENDIAN.

[Qemu-devel] [PATCH 19/19] build: Correct non-common common-obj-* to obj-*

[Tony Nguyen]

Device realizing code with MemorRegionOps endianness as
DEVICE_NATIVE_ENDIAN is not common code.

Corrected devices were identified by making the declaration of
DEVICE_NATIVE_ENDIAN conditional upon NEED_CPU_H and then listing
what failed to compile.

This patch affects various areas, maybe it is worth splitting in at 
least big/little changes? Or 3: ARM first, then big/little.

Here you say DEVICE_HOST_ENDIAN,

But here you use DEVICE_LITTLE_ENDIAN.

For 8-bit I/O port endianess doesn't matter, so I'm not sure what is the 
correct choice. Can we simply remove the .endianness line, since the 
won't be ever used?

Maybe this list is better to split your patches.

Which are the 'not used' ones?

TYPE_TPCI200 (from IndustryPack) can go with PCI.

You can put all the PrimeCell devices together (eventually with the 
other ARM devices):

  hw/audio/pl041.c
  hw/char/pl011.c
  hw/display/pl110.c
  hw/dma/pl080.c
  hw/dma/pl330.c
  hw/gpio/pl061.c
  hw/input/pl050.c
  hw/intc/pl190.c
  hw/sd/pl181.c
  hw/ssi/pl022.c
  hw/timer/pl031.c
