Hello,
The access to partitions on disks with an Amiga partition table (via
the Rigid Disk Block RDB) doesn't work anymore on my Cyrus+ board with a
FSL P50x0 PowerPC SoC [1] and on my P.A. Semi Nemo board [2] after the
block updates 2023-06-23 [3].

ASRC can be used on memory to memory case, define several
functions for m2m usage.
m2m_start_part_one: first part of the start steps
m2m_start_part_two: second part of the start steps
m2m_stop_part_one: first part of stop steps
m2m_stop_part_two: second part of stop steps
m2m_check_format: check
Implement the ASRC memory to memory function using
the v4l2 framework, user can use this function with
v4l2 ioctl interface.
User send the output and capture buffer to driver and
driver store the converted data to the capture buffer.
This feature can be shared by ASRC and EASRC drivers
Intergrate memory to memory feature to ASRC driver,
call m2m probe(), remove(), suspend() and resume()

Here is a short introduction to the issue this series is addressing:

As part of the generic HOTPLUG_SMT code, there is support for disabling
secondary SMT threads at boot time, by passing "nosmt" on the kernel
command line.
The way that is implemented is the secondary threads are brought partly
online, and then taken back offline again.
Since the maximum number of threads is now passed to
cpu_smt_set_num_threads(), checking that value is enough to know if SMT is
supported.
