| | | | | | | | | | | | Since hclgevf_reset() may fail for some reasons, so it needs an error handler to deal with it. When VF reset failed, VF can only be restored by a higher level reset asserted by PF. So, it needs to reinitialize its command queue, then it can respond to higher level reset.

| | | | | | | | | | | | | | | | | | | | | | When a Core/Global/IMP reset occurs, the hardware sets the reset status register of all PF/VF and reports a reset interrupt to all PF/VF and firmware. When receiving the reset interrupt: 1. The firmware will wait for 100 ms before resetting the hardware and clear the reset status register of all PF when hardware reset is done. 2. The PF/VF driver needs to down the netdev within 100 ms and then wait for hardware reset to finish. 3. After firmware clearing the reset status register of all PF, the PF driver reinitializes the hardware and clear the reset status register of it's VF. 4. After PF driver clearing the reset status register of VF, the VF driver reinitializes the hardware. This patch mainly add handling for the step 4.

* net: hns3: add reset handling for VF when doing PF resetHuazhong Tan2018-11-103-18/+35
| | | | | | | | | | | | | | | | | | | | | When PF performs a function reset, the hardware will reset both PF and all the VF belong to this PF. Hence, both PF's driver and VF's driver need to perform corresponding reset operations. Before PF driver asserting function reset to hardware, it firstly set up VF's hardware reset status, and inform the VF driver with HNAE3_VF_PF_FUNC_RESET, then VF driver sets this reset type to reset_pending and shechule reset task to stop IO and waits for the hardware reset status to clear. When PF driver has reinitialized the hardware and is ready to process mailbox from VF, PF driver clears VF's hardware reset status for VF to continue its reset process. Also, this patch uses readl_poll_timeout to simplify the hardware reset status waitting.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently when VF need to reset itself, it will send a cmd to PF, after receiving the VF reset requset, PF sends a cmd to inform VF to enter the reset process and send a cmd to firmware to do the actual reset for the VF, it is possible that firmware has resetted the VF, but VF has not entered the reset process, which may cause IO not stopped problem when firmware is resetting VF. This patch fixes it by adjusting the VF reset process, when VF need to reset itself, it will enter the reset process first, and it will tell the PF to send cmd to firmware to reset itself. Add member reset_pending to struct hclgevf_dev, which indicates that there is reset event need to be processed by the VF's reset task, and the VF's reset task chooses the highest-level one and clears other low-level one when it processes reset_pending. hclge_inform_reset_assert_to_vf function is unused now, but it will be used to support the PF reset with VF working, so declare it in the header file.

| | | | | | | | | | | | | | The current hns3_get_max_available_channels returns the total number of queues for the device, which makes ethtool -L set the number of queues per channel queues incorrectly, so hns3_get_max_available_channels should return the maximum available number of queues per channel, depending on the total number of queues allocated and the hardware configurations.

* net: hns3: Fix tqp array traversal condition for vfJian Shen2018-09-221-26/+24Star
| | | | | | | | | | | | | | | | | | | There are two tqp_num variables "hdev->tqp_num" and "kinfo->tqp_num" used in VF. "hdev->tqp_num" is the total tqp number allocated to the VF, and "kinfo->tqp_num" indicates the tqp number being used by the VF. Usually the two variables are equal. But for the case hdev->tqp_num larger than rss_size_max, and num_tc is 1, "kinfo->tqp_num" will be less than "hdev->tqp_num". In original codes, "hdev->tqp_num" is always used to traverse the tqp array of kinfo. It may cause null pointer error when "hdev->tqp_num" is larger than "kinfo->tqp_num" Fixes: e2cb1dec9779 ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support") Signed-off-by: Jian Shen <shenjian15@huawei.com> Signed-off-by: Peng Li <lipeng321@huawei.com> Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: David S.
