Huazhong Tan says: ==================== hns3: add code optimization for VF reset and some new reset feature Currently hardware supports below reset: 1. VF reset: triggered by sending cmd to IMP(Integrated Management Processor). Only reset specific VF function and do not affect other PF or VF. 2. PF reset: triggered by sending cmd to IMP. Only reset specific PF and it's VF. 3. PF FLR: triggered by PCIe subsystem. Only reset specific PF and it's VF. 4. VF FLR: triggered by PCIe subsystem. Only reset specific VF function and do not affect other PF or VF. 5. Core reset: triggered by writing to register. Reset most hardware unit, such as SSU, which affects all the PF and VF. 6. Global reset: triggered by writing to register. Reset all hardware unit, which affects all the PF and VF. 7. IMP reset: triggered by IMU(Intelligent Management Unit) when IMP is not longer feeding IMU's watchdog. IMU will reload the IMP firmware and IMP will perform global reset after firmware reloading, which affects all the PF and VF. Current driver only support PF/VF reset, incomplete core and global reset(lacking the vf reset handling). So this patchset adds complete reset support in hns3 driver. Also, this patchset contains some optimization related to reset. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
