[PULL 01/13] hw/sd/sdcard: Do not ignore errors in sd_cmd_to_sendingdata()

[Philippe Mathieu-Daudé]

Unfortunately when adding sd_cmd_to_sendingdata() in commit
f486bf7d109 we neglected to return any possible error. Fix.

[PULL 02/13] hw/sd/sdcard: Factor sd_response_size() out

[Philippe Mathieu-Daudé]

Set @rsplen once before switching to fill the response buffer.
This will allow to assert in a single place that the buffer is
big enough to be filled with the response.

[PULL 03/13] hw/sd/sdbus: Provide buffer size to sdbus_do_command()

[Philippe Mathieu-Daudé]

We provide to sdbus_do_command() a pointer to a buffer to be
filled with a varying number of bytes. By not providing the
buffer size, the callee can not check the buffer is big enough.
Pass the buffer size as argument to follow good practices.

sdbus_do_command() doesn't return any error, only the size filled
in the buffer. Convert the returned type to unsigned and remove
the few unreachable lines in callers.

This allow to check for possible overflow in sd_do_command().

[PULL 04/13] hw/sd/sdcard: Fill SPI response bits in card code

[Philippe Mathieu-Daudé]

ssi-sd.c contains the SPI link layer adaptation,
while sd.c contains all the SD card internal details.

We already handle the response values in sd.c, but
missed the SPI case. Complete them (fill R1, prepend
R1 in R3/R7 and always return something in SPI mode).
Remove all the duplication in ssi-sd.c.

[PULL 05/13] hw/sd/sdcard: Implement SPI R2 return value

[Philippe Mathieu-Daudé]

In SPI mode, R2 is a 2-byte value.
Implement in spi_response_r2_make() and
return SPI R2 in the SEND_STATUS commands.

[PULL 06/13] hw/sd/sdcard: Use complete SEND_OP_COND implementation in SPI mode

[Philippe Mathieu-Daudé]

While spi_cmd_SEND_OP_COND() is incomplete, sd_cmd_SEND_OP_COND()
is, except it doesn't return the correct value in SPI mode.
Correct and use, removing the need for spi_cmd_SEND_OP_COND().

[PULL 07/13] hw/sd/sdcard: Allow using SWITCH_FUNCTION in more SPI states

[Philippe Mathieu-Daudé]

In SPI mode, SWITCH_FUNCTION is valid in all mode
(except the IDLE one).

[PULL 09/13] hw/sd/sdcard: Disable checking STBY mode in SPI SEND_CSD/CID

[Philippe Mathieu-Daudé]

The card should be in STANDBY mode to process SEND_CSD or SEND_CID,
but is still in IDLE mode.

Unfortunately I don't have enough time to keep debugging this issue,
so disable the check for the time being and the next release, as it
blocks Linux. I'll keep looking.

[PULL 10/13] hw/sd/sdcard: Remove SDState::mode field

[Philippe Mathieu-Daudé]

SD card mode is a superset of its state (SDState::state),
no need to migrate it.

Use sd_mode() to get the SDCardModes from the SDCardStates.

[PULL 12/13] target/i386/cpu: Move addressable ID encoding out of compat property in CPUID[0x1]

[Philippe Mathieu-Daudé]

From: Zhao Liu <zhao1.liu@intel.com>

Currently, the addressable ID encoding for CPUID[0x1].EBX[bits 16-23]
(Maximum number of addressable IDs for logical processors in this
physical package) is covered by vendor_cpuid_only_v2 compat property.
The previous consideration was to avoid breaking migration and this
compat property makes it unfriendly to backport the commit f985a1195ba2
("i386/cpu: Fix number of addressable IDs field for CPUID.01H.EBX
[23:16]").

However, NetBSD booting is broken since the commit 88dd4ca06c83
("i386/cpu: Use APIC ID info to encode cache topo in CPUID[4]"),
because NetBSD calculates smt information via `lp_max` / `core_max` for
legacy Intel CPUs which doesn't support 0xb leaf, where `lp_max` is from
CPUID[0x1].EBX.bits[16-23] and `core_max` is from CPUID[0x4].0x0.bits[26
-31].

The commit 88dd4ca0 changed the encoding rule of `core_max` but didn't
update `lp_max`, so that NetBSD would get the wrong smt information,
which leads to the module loading failure.

Luckily, the commit f985a1195ba2 ("i386/cpu: Fix number of addressable
IDs field for CPUID.01H.EBX[23:16]") updated the encoding rule for
`lp_max` and accidentally fixed the NetBSD issue too. This also shows
that using CPUID[0x1] and CPUID[0x4].0x0 to calculate HT/SMT information
is a common practice to detect CPU topology on legacy Intel CPUs.

Therefore, it's necessary to backport the commit f985a1195ba2 to
previous stable QEMU to help address the similar issues as well. Then
the compat property is not needed any more since all stable QEMUs will
follow the same encoding way.

So, in CPUID[0x1], move addressable ID encoding out of compat property.

[PULL 13/13] hw/i386/microvm: Explicitly select ACPI_PCI

[Philippe Mathieu-Daudé]

From: Eric Auger <eric.auger@redhat.com>

With a microvm-only build based on a custom device config,
we get a link failure due to undefined reference to
build_pci_host_bridge_osc_method() which is defined in hw/acpi/pci.c and
whose compilation depends on CONFIG_ACPI_PCI. Although CONFIG_ACPI
and CONFIG_PCI are set with such configuration, implied CONFIG_ACPI_PCI
in config PCI_EXPRESS_GENERIC_BRIDGE is not selected as expected.

It Looks like CONFIG_ACPI_PCI must be enforced and this patch selects
CONFIG_ACPI_PCI in MICROVM config directly as done for PC config.

Reproducer:

../configure \
 --without-default-features \
 --target-list=x86_64-softmmu \
 --enable-kvm --disable-tcg \
 --enable-pixman \
 --enable-vnc \
 --audio-drv-list="" \
 --without-default-devices \
 --with-devices-x86_64=microvm \
 --enable-vhost-user

This new test triggers a usban error, which seems unrelated to what is 
tested.
