Patch #6 adds support for BTF-defined maps. Preserve original BTF at the time of map initialization. Patch #5 splits BTF intialization from sanitization/loading into kernel to Used anymore and makes assumption that all map definitions reside in single Patch #4 adds support for map definitions in multiple ELF sections andĭeprecates bpf_object_find_map_by_offset() API which doesn't appear to be Patch #3 refactors map initialization logic into user-provided maps and globalĭata maps, in preparation to adding another way (BTF-defined maps). BTF.ext loading loging from elf_collect(). Patch #1 centralizes commonly used min/max macro in libbpf_internal.h. See details and examples in description for patch #6. Which allows for easy extensibility, preserving forward and backwardĬompatibility. This patch set implements initial version (as discussed at LSF/MM2019Ĭonference) of a new way to specify BPF maps, relying on BTF type information, To: andrii.nakryiko, netdev, bpf, ast, daniel, kernel-team +Cc: Andrii Nakryiko ` (7 more replies) 0 siblings, 8 replies 41+ messages in threadįrom: Andrii Nakryiko 20:21 UTC ( / raw) 20:21 ` libbpf: add common min/max macro to libbpf_internal.h Andrii Nakryiko If I try to hook up any other USB 3.0 device I start seeing issues (no problems with USB 2.0 though).BTF-defined BPF map definitions All of help / color / mirror / Atom feed * BTF-defined BPF map definitions 20:21 Andrii Nakryiko
Logitech G910 Orion Spark (with Logitech Gaming Software) I just upgraded the firmware to A10 (was on A08), but still the same problem remains. To the point where the machine had to be shut down by holding the power button. I did this while keeping Device Manager open and saw that at some point USB devices stop being powered on and/or recognized. However, if I plug more than 3 devices (particularly USB 3.0 devices), the computer starts freezing.
This to me appears to be some issue with a USB hub? I have tried plugging USB devices on every port but haven't found any culprit yet. Just recently I noticed that my AW Area 51 R2 was slower to boot up, it was stuck on the BIOS logo screen for longer than normal, and then I found out that the Device Manager had the error: "Unknown USB Device (Device Descriptor Request Failed)" under "Universal Serial Bus Controllers"
