| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 78464d7681f7 ("tools/power turbostat: Add columns for clustered uncore frequency") introduced 'probe_intel_uncore_frequency_cluster()' in a way which prevents printing uncore frequency columns if either of the '-q' or '-l' options are used. Systems which do not have multiple uncore frequencies per package are unaffected by this regression. Fix the function so that uncore frequency columns are shown when either the '-l' or '-q' option is used by checking if 'quiet' is true after adding counters for the uncore frequency columns.

| * tools/power turbostat: option '-n' is ambiguousDavid Arcari2024-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases specifying the '-n' command line argument will cause turbostat to fail. For instance 'turbostat -n 1' works fine; however, 'turbostat -n 1 -d' will fail. This is the result of the first call to getopt_long_only() where "MP" is specified as the optstring. This can be easily fixed by changing the optstring from "MP" to "MPn:" to remove ambiguity between the arguments. tools/power turbostat: option '-n' is ambiguous; possibilities: '-num_iterations' '-no-msr' '-no-perf' Fixes: a0e86c90b83c ("tools/power turbostat: Add --no-perf option") Signed-off-by: David Arcari <darcari@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>

Then, if peer issues recv() with MSG_DONTWAIT, manage_oob() returns NULL, so recv() ends up with -EAGAIN. >>> c2.setblocking(False) # This causes -EAGAIN even with available data >>> c2.recv(5) Traceback (most recent call last): File "<stdin>", line 1, in <module> BlockingIOError: [Errno 11] Resource temporarily unavailable However, next recv() will return the following available data, "world". >>> c2.recv(5) b'world' When the consumed OOB skb is at the head of the queue, we need to fetch the next skb to fix the weird behaviour. Note that the issue does not happen without MSG_DONTWAIT because we can retry after manage_oob(). This patch also adds a test case that covers the issue.

Currently some selftests (e.g. access_tracking_perf_test, dirty_log_test...) add RAM regions close to max_gfn, so guest may access GPA beyond its mappable range and cause infinite loop. Adjust max_gfn in vm_compute_max_gfn() since x86 selftests already overrides vm_compute_max_gfn() specifically to deal with goofy edge cases.

If they are not fixed, tracking cannot be done. Some subtests from the userspace_pm selftest were using random numbers in their names: the client and server address IDs from $RANDOM, and the client port number randomly picked by the kernel when creating the connection. These values have been replaced by 'client' and 'server' words: that's even more helpful than showing random numbers. Note that the addresses IDs are incremented and decremented in the test: +1 or -1 are then displayed in these cases. Not to loose info that can be useful for debugging in case of issues, these random numbers are now displayed at the beginning of the test.

The map_fixed_noreplace test uses a dynamically allocated base address for the mmap()s that it tests and currently includes this in the test names that it logs so the test names that are logged are not stable between runs. It also uses multiples of PAGE_SIZE which mean that runs for kernels with different PAGE_SIZE configurations can't be directly compared. Both these factors cause issues for CI systems when interpreting and displaying results. Fix this by replacing the current test names with fixed strings describing the intent of the mappings that are logged, the existing messages with the actual addresses and sizes are retained as diagnostic prints to aid in debugging.

If no subflow have been created using the received ADD_ADDR, the related counters should not be updated, otherwise they will never be decremented for events related to this ID later on. For the moment, the number of accepted ADD_ADDR is only decremented upon the reception of a related RM_ADDR, and only if the remote address ID is currently being used by at least one subflow. In other words, if no subflow can be created with the received address, the counter will not be decremented. In this case, it is then important not to increment pm.add_addr_accepted counter, and not to modify pm.accept_addr bit. Note that this patch does not modify the behaviour in case of failures later on, e.g. if the MP Join is dropped or rejected. The "remove invalid addresses" MP Join subtest has been modified to validate this case. The broadcast IP address is added before the "valid" address that will be used to successfully create a subflow, and the limit is decreased by one: without this patch, it was not possible to create the last subflow, because: - the broadcast address would have been accepted even if it was not usable: the creation of a subflow to this address results in an error, - the limit of 2 accepted ADD_ADDR would have then been reached.

Before this patch, it could have been incremented as many times as the number of subflows connected to the linked address ID, so it could have been 0, 1 or more than 1. The "RmSubflow" is incremented after a local operation. In this case, it is normal to tied it with the number of subflows that have been actually removed. The "remove invalid addresses" MP Join subtest has been modified to validate this case. A broadcast IP address is now used instead: the client will not be able to create a subflow to this address. The consequence is that when receiving the RM_ADDR with the ID attached to this broadcast IP address, no subflow linked to this ID will be found.
