[PATCH 1/7] remoteproc: qcom: pas: Fixup the elf class for SM8450 remoteprocs

[Sibi Sankar]

From: Yogesh Lal <quic_ylal@quicinc.com>

The coredumps for the ADSP,CDSP and MPSS subsystems will be 64 bit from
SM8450 SoCs onward. Update the elf class as elf64 accordingly.

[PATCH 2/7] remoteproc: qcom: pas: Add decrypt shutdown support for modem

[Sibi Sankar]

The initial shutdown request to modem on SM8450 SoCs would start the
decryption process and will keep returning errors until the modem shutdown
is complete. Fix this by retrying shutdowns in fixed intervals.

Err Logs on modem shutdown:
qcom_q6v5_pas 4080000.remoteproc: failed to shutdown: -22
remoteproc remoteproc3: can't stop rproc: -22

[PATCH 3/7] remoteproc: qcom: pas: Mark va as io memory

[Sibi Sankar]

From: Siddharth Gupta <sidgup@codeaurora.org>

The pas driver remaps the entire carveout region using the dev_ioremap_wc()
call, which is then used in the adsp_da_to_va() calls made by the rproc
framework. This change marks the va returned by this call as an iomem va.

From: Siddharth Gupta <sidgup@codeaurora.org>

device_wakeup_enable() on its own is not capable of setting
device as wakeup capable, it needs to be used in conjunction
with device_set_wakeup_capable(). The device_init_wakeup()
calls both these functions on the device passed.

[PATCH 7/7] remoteproc: q6v5: Set q6 state to offline on receiving wdog irq

[Sibi Sankar]

From: Siddharth Gupta <sidgup@codeaurora.org>

Due to firmware bugs on the Q6 the hardware watchdog irq can be triggered
multiple times. As the remoteproc framework schedules work items for the
recovery process, if the other threads do not get a chance to run before
recovery is completed the proceeding threads will see the state of the
remoteproc as running and kill the remoteproc while it is running. This
can result in various SMMU and NOC errors. This change sets the state of
the remoteproc to offline whenever a watchdog irq is received.

Hi,


the "will be" got me thinking, whether you meant that SM8450 is the 
first SoC that features 64-bit coredumps, or it is going to come in a 
firmware update, but it was 32-bit in an earlier version.

If the latter is true, did the consumer-release BSP for hardware vendors 
include that change? Otherwise it may differ between devices, as some 
vendors are known not to update their firmwares very often if at all.

Given that you reported ^^ I found it odd that the firmware class would
change mid-program. Since I picked up the patch from list I had to dig
around for info internally. Looks like all the firmware released were
just 32 bit and it's only the tooling that does the decryption of the
dumps expects the coredumps elf to be 64 bit. Not sure why this happened
though, probably tooling upgraded in anticipation of a future fw
upgrade. Couldn't get the full history behind the decision. Anyway
the commit message needs an update will fix that in the next re-spin.
