[OLK-6.6 v2 1/4] RDMA/hns: Support flexible wqe buffer page size
driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I98HIN -------------------------------------------------------------------------- Currently, driver fixedly allocates 4K pages for user space WQE buffer even in a 64K system. This results in HW reading WQE with a granularity of 4K even in a 64K system. Considering that we support 1024-byte inline, in the scenario of using SQ inline, HW will switch pages every 4 WQEs. This will introduce a delay of about 400ns, which is an average delay of 100ns per packet. In order to improve performance, we allow user-mode driver to use more flexible WQE buffer page size allocation strategies, which allowing user-mode driver to configure WQE buffer using pages between 4K to system PAGESIZE. This feature needs to be used in conjunction with the user-mode driver. In order to ensure forward compatibility, if the user-mode driver does not support this feature, the kernel mode will continue to use a fixed 4K pagesize.

driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I98HQV -------------------------------------------------------------------------- Currently, the driver notifies user mode whether a reset has occurred through setting a shared variable to non-zero value. However, if the user fails to obtain this variable in time, the notification will be lost because this variable will be clear after completes the reset. This patch adds a new reset variable to ensure that the user mode can obtain whether the driver has been reset at any time. A non-zero value will be assigned to this variable, which will permanently become 0 once a reset occurs. During reset, the driver will assign 0 to this variable. After reset, this variable will be remapped to a page of all zeros. The userspace driver can judge whether the driver has been reset by whether this variable is 0.
