There was a problem hiding this comment.
Could we use gpio hogs for these USB devices?
In general we shouldn't amend changes that aren't upstreamable right now, such changes should be kept in a separate patches on top of the more ready patches. Hence there should be the basic tegra30-asus-p1801-t.dts that we can send to upstream today and everything else should be made on top of it.

Like commit 1cf3bfc ("bpf: Support 64-bit pointers to kfuncs") for s390x, add support for 64-bit pointers to kfuncs for LoongArch. Since the infrastructure is already implemented in BPF core, the only thing need to be done is to override bpf_jit_supports_far_kfunc_call(). Before this change, several test_verifier tests failed: # ./test_verifier | grep # | grep FAIL grate-driver#119/p calls: invalid kfunc call: ptr_to_mem to struct with non-scalar FAIL grate-driver#120/p calls: invalid kfunc call: ptr_to_mem to struct with nesting depth > 4 FAIL grate-driver#121/p calls: invalid kfunc call: ptr_to_mem to struct with FAM FAIL grate-driver#122/p calls: invalid kfunc call: reg->type != PTR_TO_CTX FAIL grate-driver#123/p calls: invalid kfunc call: void * not allowed in func proto without mem size arg FAIL grate-driver#124/p calls: trigger reg2btf_ids[reg->type] for reg->type > __BPF_REG_TYPE_MAX FAIL grate-driver#125/p calls: invalid kfunc call: reg->off must be zero when passed to release kfunc FAIL grate-driver#126/p calls: invalid kfunc call: don't match first member type when passed to release kfunc FAIL grate-driver#127/p calls: invalid kfunc call: PTR_TO_BTF_ID with negative offset FAIL grate-driver#128/p calls: invalid kfunc call: PTR_TO_BTF_ID with variable offset FAIL grate-driver#129/p calls: invalid kfunc call: referenced arg needs refcounted PTR_TO_BTF_ID FAIL grate-driver#130/p calls: valid kfunc call: referenced arg needs refcounted PTR_TO_BTF_ID FAIL #486/p map_kptr: ref: reference state created and released on xchg FAIL This is because the kfuncs in the loaded module are far away from __bpf_call_base: ffff800002009440 t bpf_kfunc_call_test_fail1 [bpf_testmod] 9000000002e128d8 T __bpf_call_base The offset relative to __bpf_call_base does NOT fit in s32, which breaks the assumption in BPF core. Enable bpf_jit_supports_far_kfunc_call() lifts this limit. Note that to reproduce the above result, tools/testing/selftests/bpf/config should be applied, and run the test with JIT enabled, unpriv BPF enabled. With this change, the test_verifier tests now all passed: # ./test_verifier ...
