pci-host: designware: Limit value range of iATU viewport register

The latest version of qemu (v8.2.0-869-g7a1dc45af5) crashes when booting
the mcimx7d-sabre emulation with Linux v5.11 and later.

qemu-system-arm: ../system/memory.c:2750: memory_region_set_alias_offset: Assertion `mr->alias' failed.

Problem is that the Designware PCIe emulation accepts the full value range
for the iATU Viewport Register. However, both hardware and emulation only
support four inbound and four outbound viewports.

The Linux kernel determines the number of supported viewports by writing
0xff into the viewport register and reading the value back. The expected
value when reading the register is the highest supported viewport index.
Match that code by masking the supported viewport value range when the
register is written. With this change, the Linux kernel reports

imx6q-pcie 33800000.pcie: iATU: unroll F, 4 ob, 4 ib, align 0K, limit 4G

as expected and supported.

We can't just embed labels directly into files like qemu-options.hx which
are included from multiple top-level rST files, because Sphinx sees the
labels as duplicate: https://github.com/sphinx-doc/sphinx/issues/9707

So add an optional argument to the SRST directive which causes a label
of the form '.. _DOCNAME-HXFILE-LABEL:' to be emitted, where 'DOCNAME'
is the name of the top level rST file, 'HXFILE' is the filename of the
.hx file, and 'LABEL' is the text provided within the 'SRST()' directive.
Using the DOCNAME of the top-level rST document means that it is unique
even when the .hx file is included from two different documents, as is
the case for qemu-options.hx

Now where the Xen PV documentation refers to the documentation for the
-initrd command line option, it can emit a link directly to it as

tests/qtest/xlnx-versal-trng-test.c: Drop use of variable length array

This test program is the last use of any variable length array in the
codebase.  If we can get rid of all uses of VLAs we can make the
compiler error on new additions.  This is a defensive measure against
security bugs where an on-stack dynamic allocation isn't correctly
size-checked (e.g.  CVE-2021-3527).

In this case the test code didn't even want a variable-sized
array, it was just accidentally using syntax that gave it one.
(The array size for C has to be an actual constant expression,
not just something that happens to be known to be constant...)

Remove the VLA usage.

15 months agosystem/vl.c: Fix handling of '-serial none -serial something'
Peter Maydell [Mon, 22 Jan 2024 16:36:06 +0000 (16:36 +0000)]
system/vl.c: Fix handling of '-serial none -serial something'

Currently if the user passes multiple -serial options on the command
line, we mostly treat those as applying to the different serial
devices in order, so that for example
 -serial stdio -serial file:filename
will connect the first serial port to stdio and the second to the
named file.

The exception to this is the '-serial none' serial device type.  This
means "don't allocate this serial device", but a bug means that
following -serial options are not correctly handled, so that
 -serial none -serial stdio
has the unexpected effect that stdio is connected to the first serial
port, not the second.

This is a very long-standing bug that dates back at least as far as
commit 998bbd74b9d81 from 2009.

Make the 'none' serial type move forward in the indexing of serial
devices like all the other serial types, so that any subsequent
-serial options are correctly handled.

Note that if your commandline mistakenly had a '-serial none' that
was being overridden by a following '-serial something' option, you
should delete the unnecessary '-serial none'.  This will give you the
same behaviour as before, on QEMU versions both with and without this
bug fix.

hw/arm: Hook up FSI module in AST2600

This patchset introduces IBM's Flexible Service Interface(FSI).

Time for some fun with inter-processor buses. FSI allows a service
processor access to the internal buses of a host POWER processor to
perform configuration or debugging.

FSI has long existed in POWER processes and so comes with some baggage,
including how it has been integrated into the ASPEED SoC.

Working backwards from the POWER processor, the fundamental pieces of
interest for the implementation are:

1. The Common FRU Access Macro (CFAM), an address space containing
   various "engines" that drive accesses on buses internal and external
   to the POWER chip. Examples include the SBEFIFO and I2C masters. The
   engines hang off of an internal Local Bus (LBUS) which is described
   by the CFAM configuration block.

2. The FSI slave: The slave is the terminal point of the FSI bus for
   FSI symbols addressed to it. Slaves can be cascaded off of one
   another. The slave's configuration registers appear in address space
   of the CFAM to which it is attached.

3. The FSI master: A controller in the platform service processor (e.g.
   BMC) driving CFAM engine accesses into the POWER chip. At the
   hardware level FSI is a bit-based protocol supporting synchronous and
   DMA-driven accesses of engines in a CFAM.

4. The On-Chip Peripheral Bus (OPB): A low-speed bus typically found in
   POWER processors. This now makes an appearance in the ASPEED SoC due
   to tight integration of the FSI master IP with the OPB, mainly the
   existence of an MMIO-mapping of the CFAM address straight onto a
   sub-region of the OPB address space.

5. An APB-to-OPB bridge enabling access to the OPB from the ARM core in
   the AST2600. Hardware limitations prevent the OPB from being directly
   mapped into APB, so all accesses are indirect through the bridge.

The implementation appears as following in the qemu device tree:

    (qemu) info qtree
    bus: main-system-bus
      type System
      ...
      dev: aspeed.apb2opb, id ""
        gpio-out "sysbus-irq" 1
        mmio 000000001e79b000/0000000000001000
        bus: opb.1
          type opb

                  type lbus
                  dev: scratchpad, id ""
                    address = 0 (0x0)

The LBUS is modelled to maintain the qdev bus hierarchy and to take
advantage of the object model to automatically generate the CFAM
configuration block. The configuration block presents engines in the
order they are attached to the CFAM's LBUS. Engine implementations
should subclass the LBusDevice and set the 'config' member of
LBusDeviceClass to match the engine's type.

CFAM designs offer a lot of flexibility, for instance it is possible for
a CFAM to be simultaneously driven from multiple FSI links. The modeling
is not so complete; it's assumed that each CFAM is attached to a single
FSI slave (as a consequence the CFAM subclasses the FSI slave).

As for FSI, its symbols and wire-protocol are not modelled at all. This
is not necessary to get FSI off the ground thanks to the mapping of the
CFAM address space onto the OPB address space - the models follow this
directly and map the CFAM memory region into the OPB's memory region.
Future work includes supporting more advanced accesses that drive the
FSI master directly rather than indirectly via the CFAM mapping, which
will require implementing the FSI state machine and methods for each of
the FSI symbols on the slave. Further down the track we can also look at
supporting the bitbanged SoftFSI drivers in Linux by extending the FSI
slave model to resolve sequences of GPIO IRQs into FSI symbols, and
calling the associated symbol method on the slave to map the access onto
the CFAM.

Testing:
    Tested by reading cfam config address 0 on rainier machine type.

hw/fsi: Aspeed APB2OPB & On-chip peripheral bus

introduced.

An APB-to-OPB bridge enabling access to the OPB from the ARM core in
the AST2600. Hardware limitations prevent the OPB from being directly
mapped into APB, so all accesses are indirect through the bridge.

The On-Chip Peripheral Bus (OPB): A low-speed bus typically found in
POWER processors. This now makes an appearance in the ASPEED SoC due
to tight integration of the FSI master IP with the OPB, mainly the
existence of an MMIO-mapping of the CFAM address straight onto a
sub-region of the OPB address space.

15 months agopflash: fix sectors vs bytes confusion in blk_pread_nonzeroes()

pflash: fix sectors vs bytes confusion in blk_pread_nonzeroes()

The following expression is incorrect because blk_pread_nonzeroes()
deals in units of bytes, not sectors:

  bytes = MIN(size - offset, BDRV_REQUEST_MAX_SECTORS)
                                              ^^^^^^^

BDRV_REQUEST_MAX_BYTES is the appropriate constant.
