arm64: dts: ti: k3-j7200-ti-ipc-firmware: Refactor IPC cfg into new dtsi

The TI K3 J7200 SoCs have multiple programmable remote processors like
R5Fs. The TI SDKs for J7200 SoCs offer sample firmwares which could be
run on these cores to demonstrate an "echo" IPC test. Those firmware
require certain memory carveouts to be reserved from system memory,
timers to be reserved, and certain mailbox configurations for interrupt
based messaging. These configurations could be different for a different
firmware.

While DT is not meant for system configurations, at least refactor these
configurations from board level DTS into a dtsi for now. This dtsi for
TI IPC firmware is board-independent and can be applied to all boards
from the same SoC Family. This gets rid of code duplication and allows
more freedom for users developing custom firmware (or no firmware) to
utilize system resources better; easily by swapping out this dtsi. To
maintain backward compatibility, the dtsi is included in all boards.

Revert "arm64: dts: ti: k3-j721e-beagleboneai64: Fix reversed C6x carveout locations"

This reverts commit 1a314099b7559690fe23cdf3300dfff6e830ecb1.

The C6x carveouts are reversed intentionally. This is due to the
requirement to keep the DMA memory region as non-cached, however the
minimum granular cache region for C6x is 16MB. So, C66x_0 marks the
entire C66x_1 16MB memory carveouts as non-cached, and uses the DMA
memory region of C66x_1 as its own, and vice-versa.

This was also called out in the original commit which introduced these
reversed carveouts:
"The minimum granularity on the Cache settings on C66x DSP
cores is 16MB, so the DMA memory regions are chosen such that
they are in separate 16MB regions for each DSP, while reserving
a total of 16 MB for each DSP and not changing the overall DSP
        remoteproc carveouts."

arm64: dts: ti: k3-am69-sk: Switch to PCIe Multilink + USB configuration

The SERDES0 instance of SERDES on the AM69 SoC is a Cadence Torrent SERDES
and it has 4 lanes which are allocated in the following manner:
Lane0 and Lane1 to PCIe1
Lane2 to PCIe3
Lane3 to USB0

Until [0], the Cadence Torrent SERDES driver only supported configuring
the SERDES for a PCIe + USB configuration whereby all lanes of the
SERDES configured for PCIe will operate at the same speed. As a result,
PCIe1 and PCIe3 instances of PCIe will either fall down to a common
speed based on the PCIe peers that they are each connected to, or, the
PCIe link could fail to be setup.

Since [0] enables support for PCIe Multilink + USB configuration, it is
now possible for the SERDES lanes allocated to PCIe1 and PCIe3 to link up
and operate at different speeds. USB continues to remain functional.

Hence, update the 'serdes0' node as well as the 'pcie1_rc' and 'pcie3_rc'
nodes to switch to the PCIe Multilink + USB configuration that is now
supported by the Cadence Torrent SERDES driver.

Pull io_uring fixes from Jens Axboe:

 - Allow vectorized payloads for send/send-zc - like sendmsg, but
   without the hassle of a msghdr.

 - Fix for an integer wrap that should go to stable, spotted by syzbot.
   Nothing alarming here, as you need to be root to hit this.
   Nevertheless, it should get fixed.

   FWIW, kudos to the syzbot crew for having much nicer reproducers now,
   and with nicely annotated source code as well. This is particularly
   useful as syzbot uses the raw interface rather than liburing,
   historically it's been difficult to turn a syzbot reproducer into a
   meaningful test case. With the recent changes, not true anymore!

If the allocated size exceeds UINT_MAX, then it's necessary to cast

practice this isn't much of a concern as the required memory size will
have been validated upfront, and accounted to the user. And > 4GB sizes
will be necessary to make the lack of a cast a problem, which greatly
exceeds normal user locked_vm settings that are generally in the kb to

then it's possible to hit this issue.

mailbox/pcc: support mailbox management of the shared buffer

Define a new, optional, callback that allows the driver to
specify how the return data buffer is allocated.  If that callback
is set,  mailbox/pcc.c is now responsible for reading from and
writing to the PCC shared buffer.

This also allows for proper checks of the Commnand complete flag
between the PCC sender and receiver.

For Type 4 channels, initialize the command complete flag prior
to accepting messages.

Since the mailbox does not know what memory allocation scheme
to use for response messages, the client now has an optional
callback that allows it to allocate the buffer for a response
message.

When an outbound message is written to the buffer, the mailbox
checks for the flag indicating the client wants an tx complete
notification via IRQ.  Upon receipt of the interrupt It will
pair it with the outgoing message. The expected use is to
free the kernel memory buffer for the previous outgoing message.

3 months agoPCI: vmd: Fix wrong kfree() in vmd_msi_free()
Nam Cao [Thu, 7 Aug 2025 08:10:51 +0000 (10:10 +0200)] 
PCI: vmd: Fix wrong kfree() in vmd_msi_free()

vmd_msi_alloc() allocates struct vmd_irq and stashes it into
irq_data->chip_data associated with the VMD's interrupt domain.
vmd_msi_free() extracts the pointer by calling irq_get_chip_data() and
frees it.

irq_get_chip_data() returns the chip_data associated with the top interrupt
domain. This worked in the past because VMD's interrupt domain was the top
domain.

But d7d8ab87e3e7 ("PCI: vmd: Switch to msi_create_parent_irq_domain()")
changed the interrupt domain hierarchy so VMD's interrupt domain is not the
top domain anymore. irq_get_chip_data() now returns the chip_data at the
MSI devices' interrupt domains. It is therefore broken for vmd_msi_free()
to kfree() this chip_data.

Fix by extracting the chip_data associated with the VMD's interrupt domain.
