c788341244 python: Remove scripts/ordereddict.py
Python 2.7 (the minimum Python version we require) provides
collections.OrderedDict on the standard library, so we don't need
to carry our own implementation.

7f2b55443a configure: Require Python 2.7 or newer
All of the supported build platforms documented in qemu-doc.texi
should already support Python 2.7.

Removing support for Python 2.6 will allow us to remove some
compatibility modules we carry in the QEMU tree:

* scripts/argparse.py
* scripts/ordereddict.py

Python 2.6 is also not receiving bug fixes upstream and is not
supported by pylint, which makes it harder to keep the code
compatible with both Python 2 and Python 3.

8f4202fb10 i386: Populate AMD Processor Cache Information for cpuid 0x8000001D
Add information for cpuid 0x8000001D leaf. Populate cache topology information
for different cache types (Data Cache, Instruction Cache, L2 and L3) supported
by 0x8000001D leaf. Please refer to the Processor Programming Reference (PPR)
for AMD Family 17h Model for more details.

a9f27ea9ad i386: Clean up cache CPUID code
Always initialize CPUCaches structs with cache information, even
if legacy_cache=true.  Use different CPUCaches struct for
CPUID[2], CPUID[4], and the AMD CPUID leaves.

This will simplify a lot the logic inside cpu_x86_cpuid().

c173723f24 ide: introduce ide_transfer_start_norecurse
For the case where the end_transfer_func is also the caller of
ide_transfer_start, the mutual recursion can lead to unlimited
stack usage.  Introduce a new version that can be used to change
tail recursion into a loop, and use it in trace_ide_atapi_cmd_reply_end.

The ATAPI_INT_REASON_IO interrupt is raised when I/O starts, but in the
AHCI case ide_set_irq was actually called at the end of a mutual recursion.
Move it early, with the side effect that ide_transfer_start becomes a tail
call in ide_atapi_cmd_reply_end.

There is code checking s->end_transfer_func and it was not taught about
ide_transfer_cancel.  We can just use ide_transfer_stop because
s->end_transfer_func is only ever called in the DRQ phase.

ide_transfer_cancel can then be removed, since it would just be
calling ide_transfer_halt.

formalize the fact that the callback (of which ahci_start_transfer is
the sole implementation) takes care of the transfer too: rename it to
pio_transfer and, if it is present, call the end_transfer_func as soon

956556e131 ahci: move PIO Setup FIS before transfer, fix it for ATAPI commands
The PIO Setup FIS is written in the PIO:Entry state, which comes before
the ATA and ATAPI data transfer states.  As a result, the PIO Setup FIS
interrupt is now raised before DMA ends for ATAPI commands, and tests have
to be adjusted.

This is also hinted by the description of the command header in the AHCI
specification, where the "A" bit is described as

    When ‘1’, indicates that a PIO setup FIS shall be sent by the device
    indicating a transfer for the ATAPI command.

and also by the description of the ACMD (ATAPI command region):

    The ATAPI command must be either 12 or 16 bytes in length. The length
    transmitted by the HBA is determined by the PIO setup FIS that is sent
    by the device requesting the ATAPI command.

QEMU, which conflates the "generator" and the "receiver" of the FIS into
one device, always uses ATAPI_PACKET_SIZE, aka 12, for the length.

27e4648ce9 libqos/ahci: track sector size
It's not always 512, and it does wind up mattering for PIO tranfers,
because this means DRQ blocks are four times as big for ATAPI.
Replace an instance of 2048 with the correct define, too.

This patch by itself winds changing no behavior. fis->count is ignored
for CMD_PACKET, and sect_count only gets used in non-ATAPI cases.

than the network loader and expects some magic bytes in the header

we've got to add them in our boot code here, too.

e538916366 ahci: make port read traces more descriptive
A trace is added to let us watch unimplemented registers specifically,
as these are more likely to cause us trouble. Otherwise, the port read
traces now tell us what register is getting hit, which is nicer.

5694c7eacc ahci: fix PxCI register race
Fixes: https://bugs.launchpad.net/qemu/+bug/1769189

AHCI presently signals completion prior to the PxCI register being
cleared to indicate completion. If a guest driver attempts to issue
a new command in its IRQ handler, it might be surprised to learn there
is still a command pending.

In the case of Windows 10's boot driver, it will actually poll the IRQ
register hoping to find out when the command is done running -- which
will never happen, as there isn't a command running.

Fix this: clear PxCI in ahci_cmd_done and not in the asynchronous BH.
Because it now runs synchronously, we don't need to check if the command
is actually done by spying on the ATA registers. We know it's done.

d1b322182b sdcard: Disable SEND_IF_COND (CMD8) for Spec v1
CMD8 is "Reserved" in Spec v1.10.

Spec v2.00 introduces the SEND_IF_COND command:

  6.4.1 Power Up

    CMD8 is newly added in the Physical Layer Specification Version
    2.00 to support multiple voltage ranges and used to check whether
    the card supports supplied voltage. The version 2.00 or later host
    shall issue CMD8 and verify voltage before card initialization.
    The host that does not support CMD8 shall supply high voltage range.
