2022-07-20Merge branch 'net-ipa-move-configuration-data-files'Jakub Kicinski
Alex Elder says: ==================== net: ipa: move configuration data files This series moves the "ipa_data-vX.Y.c" files into a subdirectory. The first patch adds a Makefile variable containing the list of supported IPA versions, and uses it to simplify the way these files are specified. ==================== Link: https://lore.kernel.org/r/20220719150827.295248-1-elder@linaro.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-20net: ipa: move configuration data files into a subdirectoryAlex Elder
Reduce the clutter in the main IPA source directory by creating a new "data" subdirectory, and locating all of the configuration data files in there. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-20net: ipa: list supported IPA versions in the MakefileAlex Elder
Create a variable in the Makefile listing the IPA versions supported by the driver. Use that to create the list of configuration data object files used (rather than listing them all individually). Add a SPDX license comment. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-20Merge branch 'net-ipa-small-transaction-updates'Jakub Kicinski
Alex Elder says: ==================== net: ipa: small transaction updates Version 2 of this series corrects a misspelling of "outstanding" pointed out by the netdev test bots. (For some reason I don't see that when I run "checkpatch".) I found and fixed a second instance of that word being misspelled as well. This series includes three changes to the transaction code. The first adds a new transaction list that represents a distinct state that has not been maintained. The second moves a field in the transaction information structure, and reorders its initialization a bit. The third skips a function call when it is known not to be necessary. The last two are very small "leftover" patches. ==================== Link: https://lore.kernel.org/r/20220719181020.372697-1-elder@linaro.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-20net: ipa: fix an outdated commentAlex Elder
Since commit 8797972afff3d ("net: ipa: remove command info pool"), we don't allocate "command info" entries for command channel transactions. Fix a comment that seems to suggest we still do. (Even before that commit, the comment was out of place.) Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-20net: ipa: report when the driver has been removedAlex Elder
When the IPA driver has completed its initialization and setup stages, it emits a brief message to the log. Add a small message that reports when it has been removed. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-20net: ipa: skip some cleanup for unused transactionsAlex Elder
In gsi_trans_free(), there's no point in ipa_gsi_trans_release() if a transaction is unused. No used TREs means no IPA layer resources to clean up. So only call ipa_gsi_trans_release() if at least one TRE was used. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-20net: ipa: rearrange transaction initializationAlex Elder
The transaction map is really associated with the transaction pool; move its definition earlier in the gsi_trans_info structure. Rearrange initialization in gsi_channel_trans_init() so it sets the tre_avail value first, then initializes the transaction pool, and finally allocating the transaction map. Update comments. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-07-20net: ipa: add a transaction committed listAlex Elder
We currently put a transaction on the pending list when it has been committed. But until the channel's doorbell rings, these transactions aren't actually "owned" by the hardware yet. Add a new "committed" state (and list), to represent transactions that have been committed but not yet sent to hardware. Define "pending" to mean committed transactions that have been sent to hardware but have not yet completed.

2022-07-20net: ipa: add an endpoint device attribute groupAlex Elder
Create a new attribute group meant to provide a single place that defines endpoint IDs that might be needed by user space. Not all defined endpoints are presented, and only those that are defined will be made visible. The new attributes use "extended" device attributes to hold endpoint IDs, which is a little more compact and efficient. Reimplement the existing modem endpoint ID attribute files using common code.

2022-07-20watchqueue: make sure to serialize 'wqueue->defunct' properlyLinus Torvalds
When the pipe is closed, we mark the associated watchqueue defunct by calling watch_queue_clear(). However, while that is protected by the watchqueue lock, new watchqueue entries aren't actually added under that lock at all: they use the pipe->rd_wait.lock instead, and looking up that pipe happens without any locking. The watchqueue code uses the RCU read-side section to make sure that the wqueue entry itself hasn't disappeared, but that does not protect the pipe_info in any way. So make sure to actually hold the wqueue lock when posting watch events, properly serializing against the pipe being torn down.

2022-07-20perf/x86/intel/lbr: Fix unchecked MSR access error on HSWKan Liang
The fuzzer triggers the below trace. [ 7763.384369] unchecked MSR access error: WRMSR to 0x689 (tried to write 0x1fffffff8101349e) at rIP: 0xffffffff810704a4 (native_write_msr+0x4/0x20) [ 7763.397420] Call Trace: [ 7763.399881] <TASK> [ 7763.401994] intel_pmu_lbr_restore+0x9a/0x1f0 [ 7763.406363] intel_pmu_lbr_sched_task+0x91/0x1c0 [ 7763.410992] __perf_event_task_sched_in+0x1cd/0x240 On a machine with the LBR format LBR_FORMAT_EIP_FLAGS2, when the TSX is disabled, a TSX quirk is required to access LBR from registers. The lbr_from_signext_quirk_needed() is introduced to determine whether the TSX quirk should be applied. However, the lbr_from_signext_quirk_needed() is invoked before the intel_pmu_lbr_init(), which parses the LBR format information. Without the correct LBR format information, the TSX quirk never be applied. Move the lbr_from_signext_quirk_needed() into the intel_pmu_lbr_init(). Checking x86_pmu.lbr_has_tsx in the lbr_from_signext_quirk_needed() is not required anymore. Both LBR_FORMAT_EIP_FLAGS2 and LBR_FORMAT_INFO have LBR_TSX flag, but only the LBR_FORMAT_EIP_FLAGS2 requirs the quirk. Update the comments accordingly.
