2021-10-28octeontx2-af: Display all enabled PF VF rsrc_alloc entries.Rakesh Babu1-32/+106
Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size.

sk->sk_err appears to expect a positive value, a convention that ktls doesn't always follow and that leads to memory corruption in other code. For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

2021-10-27drm/amd/display: Fix deadlock when falling back to v2 from v3Nicholas Kazlauskas1-4/+2
[Why] A deadlock in the kernel occurs when we fallback from the V3 to V2 add_topology_to_display or remove_topology_to_display because they both try to acquire the dtm_mutex but recursive locking isn't supported on mutex_lock(). [How] Make the mutex_lock/unlock more fine grained and move them up such that they're only required for the psp invocation itself.

2021-10-27drm/amd/display: Fallback to clocks which meet requested voltage on DCN31Michael Strauss1-3/+10
[WHY] On certain configs, SMU clock table voltages don't match which cause parser to behave incorrectly by leaving dcfclk and socclk table entries unpopulated. [HOW] Currently the function that finds the corresponding clock for a given voltage only checks for exact voltage level matches. In the case that no match gets found, parser now falls back to searching for the max clock which meets the requested voltage (i.e. its corresponding voltage is below requested).

2021-10-27tracing: Do not warn when connecting eprobe to non existing eventSteven Rostedt (VMware)1-2/+2
When the syscall trace points are not configured in, the kselftests for ftrace will try to attach an event probe (eprobe) to one of the system call trace points. This triggered a WARNING, because the failure only expects to see memory issues. But this is not the only failure. The user may attempt to attach to a non existent event, and the kernel must not warn about it.
