In a qcspmi_cmd_read() error case, the register is only returning the error bit, not SPMI_STATUS_DONE. Therefore, catch the error at the right place, and print the specific error type. ok patrick@ |

| message |
Make sysctl_int() and sysctl_int_lower() mp-safe and unlock KERN_HOSTID. The only difference between sysctl_int() and sysctl_int_bounded() is the range check, so sysctl_int() is just sysctl_int_bounded(..., INT_MIN, INT_MAX). sysctl_int() is not the fast path, so this useless check is not significant. Mp-safe sysctl_int() is meaningless for sysctl_int_lower(), so rework it in the sysctl_int_bounded() style. This time all affected paths are kernel locked, but this doesn't make sysctl_int_lower() worse. Change `hostid' type to the type of int. It only stored but never used within kernel, userland accesses it through sysctl_int(). Nothing changes, but variable becomes consistent with sysctl_int(). ok bluhm |

Introduce qwz(4), a work-in-progress port of the Linux ath12k driver. This driver is not working yet, it's a copy of qwx(4) which bit-by-bit will be adjusted to work on the newer generation of chips. Even though this is only a minor bump over the previous generation, the changes are large enough that bringup, debugging and long-term maintenance would suffer trying to squash them into a single driver. This can be reconsidered once we have reached a stable state. |

Push kernel lock down to net_sysctl(). All except PF_MPLS paths are mp-safe: - net_link_sysctl() and following net_ifiq_sysctl() only return EOPNOTSUPP; - uipc_sysctl() - mp-safe atomic access to integers; - bpf_sysctl() - mp-safe atomic access to integers; - pflow_sysctl() - returns statistics from per-CPU counters; - pipex_sysctl() - mp-safe atomic access to integer; Push kernel lock down to mpls_sysctl(). sysctl_int_bounded() do copying with local variable, so context switch is safe. No need to wire memory or take `sysctl_lock' rwlock(9). Keep protocols locked as they was include pages wiring. Copying will not sleep - no network slowdown while doing it with net lock held. ok bluhm |

Implement bounce buffering for AMD SEV in amd64 bus dma. When running as SEV guest, as indicated by variable cpu_sev_guestmode, allocate additional pages for each segment on dma map creation. These pages are mapped with the PMAP_NOCRYPT attribute, i.e. the crypt bit is not set in the PTE. Thus, these pages are shared with the hypervisor. When the map is loaded with actual pages, the address in the descriptor is replaced by the corresponding bounce buffer. Using bus_dmamap_sync(), data is copied from the encrypted pages used by guest drivers to the unencrypted bounce buffers shared with the hypervisor, and vice versa. If the kernel is not running in SEV guest mode, which means as normal host or non-SEV guest, no bounce buffers are used. from hshoexer@; based on ancient code of mickey@; OK kettenis@ |
