net: hns3: refactor dump reg of debugfs
mainline inclusion from mainline-master commit d96b0e59 category: feature bugzilla: 173966 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d96b0e59468dcbd61417b7dd31985a700e58d3b2 ---------------------------------------------------------------------- Currently, the debugfs command for reg is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create some files "bios_common/ssu/igu_egu/rpu/ncsi/rtc/ppp/rcb/tqp/mac" for it, and query it by command "cat xxx", return the result to userspace, rather than record in dmesg. The display style is below: $ cat bios_common BP_CPU_STATE: 0x0 DFX_MSIX_INFO_NIC_0: 0xc000 DFX_MSIX_INFO_NIC_1: 0x0 DFX_MSIX_INFO_NIC_2: 0x0 DFX_MSIX_INFO_NIC_3: 0x0 DFX_MSIX_INFO_ROC_0: 0xc000 DFX_MSIX_INFO_ROC_1: 0x0 DFX_MSIX_INFO_ROC_2: 0x0 DFX_MSIX_INFO_ROC_3: 0x0 Signed-off-by: NYufeng Mo <moyufeng@huawei.com> Signed-off-by: NHuazhong Tan <tanhuazhong@huawei.com> Signed-off-by: NDavid S.
