2022-05-21i2c: npcm: Handle spurious interruptsTali Perry1-29/+62
On some platforms in rare cases (1 to 100,000 transactions), the i2c gets a spurious interrupt which means that we enter an interrupt but in the interrupt handler we don't find any status bit that points to the reason we got this interrupt. This may be a case of a rare HW issue or signal integrity issue that is still under investigation. In order to overcome this we are doing the following: 1. Disable incoming interrupts in master mode only when slave mode is not enabled. 2. Clear end of busy (EOB) after every interrupt. 3. Clear other status bits (just in case since we found them cleared) 4. Return correct status during the interrupt that will finish the transaction. On next xmit transaction if the bus is still busy the master will issue a recovery process before issuing the new transaction.

When a group of messages are sent from user space as a set, if the last message has less than Tx FIFO DEPTH number of bytes to transfer, Tx half empty interrupt is triggered continuously from the hardware. It is due to Bus not busy interrupt coming along with Tx half empty and tx empty. Hence, service the Tx interrupts before Bus not busy interrupt to update the i2c message status correctly.

2022-05-14i2c: cadence: Increase timeout per message if necessaryLucas Tanure1-2/+10
Timeout as 1 second sets an upper limit on the length of the transfer executed, but there is no maximum length of a write or read message set in i2c_adapter_quirks for this controller. This upper limit affects devices that require sending large firmware blobs over I2C. To remove that limitation, calculate the minimal time necessary, plus some wiggle room, for every message and use it instead of the default one second, if more than one second.

2022-05-04i2c: mediatek: Optimize master_xfer() and avoid circular lockingAngeloGioacchino Del Regno1-4/+7
Especially (but not only) during probe, it may happen that multiple devices are communicating via i2c (or multiple i2c busses) and sometimes while others are probing asynchronously. For example, a Cr50 TPM may be filling entropy (or userspace may be reading random data) while the rt5682 (i2c) codec driver reads/sets some registers, like while getting/setting a clock's rate, which happens both during probe and during system operation. In this driver, the mtk_i2c_transfer() function (which is the i2c .master_xfer() callback) was granularly managing the clocks by performing a clk_bulk_prepare_enable() to start them and its inverse. This is not only creating possible circular locking dependencies in the some cases (like former explanation), but it's also suboptimal, as clk_core prepare/unprepare operations are using mutex locking, which creates a bit of unwanted overhead (for example, i2c trackpads will call master_xfer() every few milliseconds!). With this commit, we avoid both the circular locking and additional overhead by changing how we handle the clocks in this driver: - Prepare the clocks during probe (and PM resume) - Enable/disable clocks in mtk_i2c_transfer() - Unprepare the clocks only for driver removal (and PM suspend) For the sake of providing a full explanation: during probe, the clocks are not only prepared but also enabled, as this is needed for some hardware initialization but, after that, we are disabling but not unpreparing them, leaving an expected state for the aforementioned clock handling strategy.

2022-04-09perf tools: Add external commands to list-cmdsMichael Petlan1-0/+4
The `perf --list-cmds` output prints only internal commands, although there is no reason for that from users' perspective. Adding the external commands to commands array with NULL function pointer allows printing all perf commands while not changing the logic of command handler selection.

If a perf event doesn't fit into remaining buffer space return NULL to remap buf and fetch the event again. Keep the logic to error out on inadequate input from fuzzing.

2022-04-09perf bench: Fix epoll bench to correct usage of affinity for machines with ↵Athira Rajeev2-12/+38
#CPUs > 1K The 'perf bench epoll' testcase fails on systems with more than 1K CPUs. Testcase: perf bench epoll all Result snippet: <<>> Run summary [PID 106497]: 1399 threads monitoring on 64 file-descriptors for 8 secs. perf: pthread_create: No such file or directory <<>> In epoll benchmarks (ctl, wait) pthread_create is invoked in do_threads from respective bench_epoll_* function. Though the logs shows direct failure from pthread_create, the actual failure is from "sched_setaffinity" returning EINVAL (invalid argument). This happens because the default mask size in glibc is 1024. To overcome this 1024 CPUs mask size limitation of cpu_set_t, change the mask size using the CPU_*_S macros. Patch addresses this by fixing all the epoll benchmarks to use CPU_ALLOC to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the mask.

2022-04-09perf: arm-spe: Fix perf report --mem-modeJames Clark1-0/+6
Since commit bb30acae4c4dacfa ("perf report: Bail out --mem-mode if mem info is not available") "perf mem report" and "perf report --mem-mode" don't allow opening the file unless one of the events has PERF_SAMPLE_DATA_SRC set. SPE doesn't have this set even though synthetic memory data is generated after it is decoded. Fix this issue by setting DATA_SRC on SPE events. This has no effect on the data collected because the SPE driver doesn't do anything with that flag and doesn't generate samples.
