[PATCH v1 01/10] hw/i2c/aspeed_i2c: Fix Out-of-Bounds access by using dynamic register array

[Jamin Lin]

The ASPEED I2C controller emulation used a fixed-size register array
(28 dwords) for all SoC variants, while multiple ASPEED SoCs
(AST2600, AST1030, AST2700) expose a larger MMIO register window
(e.g. reg_size = 0x80).

This mismatch allows MMIO accesses beyond the allocated register
array, leading to out-of-bounds reads in the I2C controller model.

Fix this by converting the register storage to a dynamically allocated
array sized according to the controller class reg_size. The register
array is now allocated during bus realize and free on unrealize,
ensuring safe access across different ASPEED SoC implementations.

This change eliminates I2C register out-of-bounds access caused by
SoC-specific register size differences.

hmm, why not use VMSTATE_VARRAY_UINT32 ?

g_new0 ? even if the memset in reset will set regs[] contents to 0.

This patch is redundant with patch 10. Probably you had an extra
patch file in the directory you used to send the series. I will
ignore it for now but this confuses b4.

Thanks for report it.
It is my patch folder issue.

[PATCH v1 02/10] hw/i2c/aspeed_i2c: Increase I2C device register size to 0xA0

[Jamin Lin]

According to the AST2700 A1 datasheet, the register space for each I2C
device instance has been expanded from 0x80 bytes to 0xA0 bytes.

Update the AST2700 I2C controller configuration to reflect the new
register layout by increasing the per-device register size to 0xA0
and adjusting the register gap size accordingly.

Was that change introduced with the A1 ? or A0 ?

The change was introduced in A1.
Both A1 and A2 use the same device register size of 0xA0.

[PATCH v1 03/10] hw/misc/aspeed_scu: Remove unused SoC silicon revision definitions

[Jamin Lin]

Several legacy Aspeed SoC silicon revision definitions are no longer
used by any machine models or runtime logic.

Remove unused silicon revision macros and corresponding entries from
the silicon revision table to reduce dead code and improve
maintainability.

No functional change intended.

[PATCH v1 04/10] hw/misc/aspeed_scu: Add AST2700 A2 silicon revisions

[Jamin Lin]

Add silicon revision definitions for AST2700 A2, and include
them in the list of supported Aspeed silicon revisions.

This allows newer AST27x0 A2 silicon to be correctly identified via
the SCU silicon revision register.

[PATCH v1 05/10] hw/arm/aspeed_ast27x0: Add AST2700 A2 SoC support

[Jamin Lin]

Introduce a new AST2700 A2 SoC variant by adding a dedicated class
initialization function.

This commit sets the A2 silicon revision and defines its SoC
capabilities, including CPU type, SRAM size, peripheral counts, and
CPU topology, while reusing the existing IRQ and memory maps.

I have updated the commit log as follows:

AST2700 A2 is functionally identical to AST2700 A1.
There are no changes to the IRQ layout, memory map, or peripheral
configuration. The only difference is the silicon revision.

This commit introduces a dedicated AST2700 A2 SoC type by reusing
the existing AST2700 A1 implementation and setting the A2 silicon
revision accordingly.

[PATCH v1 06/10] hw/arm/aspeed_ast27x0_evb: Add AST2700 A2 EVB machine

[Jamin Lin]

Add a new AST2700 A2 EVB machine to model the newer A2 silicon.

The "ast2700-evb" machine alias is moved to the AST2700 A2 EVB, making
it the default AST2700 evaluation board. The existing AST2700 A1 EVB
machine remains available as "ast2700a1-evb".

[PATCH v1 07/10] tests/qtest/ast2700-hace-test: Use ast2700-evb alias for AST2700 HACE tests

[Jamin Lin]

Update AST2700 HACE qtests to use the "ast2700-evb" machine alias
instead of a specific silicon revision.

The AST2700 A1 and A2 revisions are compatible for the HACE model, so
the tests do not depend on a particular EVB revision. Using the
"ast2700-evb" alias ensures the tests always run the latest
supported AST2700 silicon revision.

I wonder if we need to test both machines. The test is already quite long.

On my test system :

   qemu:func-aarch64-aspeed_ast2700             OK              119.68s   3 subtests passed

With both machines :

   qemu:func-aarch64-aspeed_ast2700             OK              219.79s   6 subtests passed

Thanks,

C.

If the machines are very similar, it's maybe better to mark one of the tests 
with a decorator (skipSlowTest maybe), so we don't have to execute it by 
default, but we still have the test around if we need it.

It might also be nice to have them be a separate top level test,
so that the tests can be run in parallel. AIUI having 1 test
with 6 subtests forces all 6 to run in sequence, whereas with
2 tests and 3 subtests each you can at least use 2 host CPUs.
Or does the qtest subtest handling include parallelism?

No, there is no parallel execution for subtests, in neither the qtest nor 
the functional testing framework. So yes, if you want to execute this in 
parallel, put it into separate files.

Thanks for the review and the suggestions.

I plan to rename test_aspeed_ast2700.py to test_aspeed_ast2700a1.py for AST2700 A1 testing.
Then, I will add a new test_aspeed_ast2700.py for AST2700 A2 testing.
This test will cover the latest EVB machine and SoC.

Please let me know if you have any suggestions.

Thanks-Jamin

[PATCH v1 09/10] hw/arm/aspeed_ast27x0-fc: Switch AST2700 FC machine to A2 SoC

[Jamin Lin]

Update the AST2700 FC machine to use the AST2700 A2 SoC model instead of
the A1-specific variant.

This change removes A1-specific naming and definitions from the FC
machine and aligns it with the newer AST2700 A2 silicon.

The ast2700a2-evb machine is largely identical to ast2700a1-evb.
The only difference is the default DRAM size, which is increased
to 2 GB. So, I updated the DRAM size to 2GiB.
Should I separate the patch to update the DRAM size?

That would be nice.


I let you decide if a Fixes tag is needed.

It would nice if you could provide a summary of the changes
introduced in the A2 revision compared to the A1. That in
the cover letter and in the commit log of the patch adding
support. We're curious !

Thanks,

Thanks for the review and the suggestion.

I have added a summary of the differences between AST2700 A1 and AST2700 A2 to the commit log of the patch that adds A2 support.
The same information has also been added to the cover letter.

For clarity, the differences are:
V2:
 1. AST2700 A2 is functionally identical to AST2700 A1. There are no changes to the IRQ layout, memory map, or peripheral configuration; the only difference is the silicon revision.
 2. The ast2700a2-evb machine is largely identical to ast2700a1-evb. The only difference is the default DRAM size, which is increased to 2 GB.
 3. The I2C out-of-bounds fix has been separated into a new patch series.

Thanks,
Jamin
