Last handful of arm patches before softfreeze...
1
target-arm queue: the big stuff here is the final part of
2
rth's patches for Cortex-A76 and Neoverse-N1 support;

When requesting JEDEC data using the JEDEC_READ command, the Linux kernel
3
NUVIA was acquired by Qualcomm in March 2021, but kept functioning on
4
always requests 6 bytes. The current implementation only returns three
4
separate infrastructure for a transitional period. We've now switched
5
bytes, and interprets the remaining three bytes as new commands.

over to contributing as Qualcomm Innovation Center (quicinc), so update

While this does not matter most of the time, it is at the very least

my email address to reflect this.

confusing. To avoid the problem, always report up to 6 bytes of JEDEC
8
data. Fill remaining data with 0.

New patch

1
From: Richard Henderson <richard.henderson@linaro.org>
2
3
Drop el3_no_el2_cp_reginfo, el3_no_el2_v8_cp_reginfo, and the local
4
vpidr_regs definition, and rely on the squashing to ARM_CP_CONST
5
while registering for v8.
6
7
This is a behavior change for v7 cpus with Security Extensions and
8
without Virtualization Extensions, in that the virtualization cpregs
9
are now correctly not present. This would be a migration compatibility
10
break, except that we have an existing bug in which migration of 32-bit
11
cpus with Security Extensions enabled does not work.

IMX6UL USB controllers are quite similar to IMX7 USB controllers.

Drop zcr_no_el2_reginfo and merge the 3 registers into one array,

Wire them up the same way.

The only real difference is that wiring up phy devices is necessary

to avoid phy reset timeouts in the Linux kernel.

4
but none of them are accessible from user-only, therefore
5
define them only in system mode.

This will shortly be used from cpu_tcg.c also.

From: Richard Henderson <richard.henderson@linaro.org>

3
Instead of starting with cortex-a15 and adding v8 features to
4
a v7 cpu, begin with a v8 cpu stripped of its aarch64 features.
5
This fixes the long-standing to-do where we only enabled v8
6
features for user-only.

From: Richard Henderson <richard.henderson@linaro.org>

3
The only portion of FEAT_Debugv8p2 that is relevant to QEMU
4
is CONTEXTIDR_EL2, which is also conditionally implemented
5
with FEAT_VHE. The rest of the debug extension concerns the
6
External debug interface, which is outside the scope of QEMU.

This extension concerns changes to the External Debug interface,
4
with Secure and Non-secure access to the debug registers, and all
5
of it is outside the scope of QEMU. Indicating support for this
6
is mandatory with FEAT_SEL2, which we do implement.

3
Add only the system registers required to implement zero error
4
records. This means that all values for ERRSELR are out of range,
5
which means that it and all of the indexed error record registers
6
need not be implemented.
7
8
Add the EL2 registers required for injecting virtual SError.

Add basic USB PHY support as implemented in i.MX23, i.MX28, i.MX6,

Virtual SError exceptions are raised by setting HCR_EL2.VSE,
4
and i.MX7 SoCs.

and are routed to EL1 just like other virtual exceptions.

The only support really needed - at least to boot Linux - is support
7
for soft reset, which needs to reset various registers to their initial
8
value. Otherwise, just record register values.

Introduce two new properties to the DT generated on machine generation:
8
Message-id: 20200313014551.12554-4-linux@roeck-us.net
8
- machine-version-major
9
To be incremented when a platform change makes the machine
10
incompatible with existing firmware.
11
- machine-version-minor
12
To be incremented when functionality is added to the machine
13
without causing incompatibility with existing firmware.
14
to be reset to 0 when machine-version-major is incremented.
15
16
This versioning scheme is *neither*:
17
- A QEMU versioned machine type; a given version of QEMU will emulate
18
a given version of the platform.
19
- A reflection of level of SBSA (now SystemReady SR) support provided.
20
21
The version will increment on guest-visible functional changes only,
22
akin to a revision ID register found on a physical platform.
23
24
These properties are both introduced with the value 0.
25
(Hence, a machine where the DT is lacking these nodes is equivalent
26
to version 0.0.)

Currently, the SMP configuration isn't considered when the CPU
4
topology is populated. In this case, it's impossible to provide
5
the default CPU-to-NUMA mapping or association based on the socket
6
ID of the given CPU.

8
This takes account of SMP configuration when the CPU topology
9
is populated. The die ID for the given CPU isn't assigned since
10
it's not supported on arm/virt machine. Besides, the used SMP
11
configuration in qtest/numa-test/aarch64_numa_cpu() is corrcted
12
to avoid testing failure

With current implementation of mc->get_default_cpu_node_id(),
37
CPU#0 to CPU#5 are associated with NODE#0 to NODE#5 separately.
38
That's incorrect because CPU#0/1/2 should be associated with same

NUMA node because they're seated in same socket.
40
41
This fixes the issue by considering the socket ID when the default
42
CPU-to-NUMA association is provided in virt_possible_cpu_arch_ids().
43
With this applied, no more CPU topology broken warnings are seen
44
from the Linux guest. The 6 CPUs are associated with NODE#0/1, but
45
there are no CPUs associated with NODE#2/3/4/5.
