[ Upstream commitee89921da4] Do not allow to set phase adjust value for a pin if PF reset is in progress, this would cause confusing netlink extack errors as the firmware cannot process the request properly during the reset time. Return (-EBUSY) and report extack error for the user who tries configure pin phase adjust during the reset time. Test by looping execution of below steps until netlink error appears: - perform PF reset $ echo 1 > /sys/class/net/<ice PF>/device/reset - change pin phase adjust value: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \ --do pin-set --json '{"id":0, "phase-adjust":1000}' Fixes:90e1c90750("ice: dpll: implement phase related callbacks") Reviewed-by: Igor Bagnucki <igor.bagnucki@intel.com> Signed-off-by: Arkadiusz Kubalewski <arkadiusz.kubalewski@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
