2022-06-27Input: iqs7222 - handle reset during ATIJeff LaBundy1-3/+6
If the device suffers a spurious reset during ATI, there is no point in enduring any further retries. Instead, simply return successfully from the polling loop. In this case, the interrupt handler will intervene and recognize the device has been reset. It then proceeds to initialize the device and trigger ATI once more. As part of this change, swap the order of status field evaluation to match that of the interrupt handler, and correct a nearby off-by-one error that causes an error message to suggest the final attempt will be retried.

2022-06-27Input: iqs7222 - acknowledge reset before writing registersJeff LaBundy1-3/+29
If the device suffers a spurious reset while reacting to a previous spurious reset, the second reset interrupt is preempted because the ACK_RESET bit is written last. To solve this problem, write the ACK_RESET bit prior to writing any other registers. This ensures that any registers written before the second spurious reset will be rewritten. Last but not least, the order in which the ACK_RESET bit is written relative to the second filter beta register is important for select variants of silicon. Enforce the correct order so as to not clobber the system status register.

2022-06-27Input: iqs7222 - protect volatile registersJeff LaBundy1-4/+14
Select variants of silicon silently mirror part of the event mask register to the system setup register (0xD0), and vice versa. For the following sequence: 1. Read registers 0xD0 onward and store their contents. 2. Modify the contents, including event mask fields. 3. Write registers 0xD0 onward with the modified contents. 4. Write register 0xD0 on its own again later, using the contents from step 1 to populate any reserved fields. ...the event mask register (e.g. address 0xDA) has been corrupted by writing register 0xD0 with contents that were made stale after step 3. To solve this problem, read register 0xD0 once more between steps 3 and 4. When register 0xD0 is written during step 4, the portion which is mirrored to the event mask register already matches what was written in step 3.

2022-06-27Input: iqs7222 - fortify slider event reportingJeff LaBundy1-38/+58
The release cycle of any key mapped to a slider gesture relies upon trailing interrupts generated by other unmasked sources, the timing and presence of which are inconsistent. To solve this problem, explicitly report a release cycle to emulate a full keystroke. Also, unmask touch interrupts if the slider press event is defined; this ensures the device reports a final interrupt with coordinate = 0xFFFF once the finger is lifted. As a result of how the logic has been refactored, the press/release event can now be mapped to a GPIO. This is more convenient than the previous solution, which required each channel within the slider to specify the same GPIO. As part of this change, use the device's resolution rather than its number of interrupt status registers to more safely determine if it is capable of reporting gestures. Last but not least, make the code a bit simpler by eliminating some unnecessarily complex conditional statements and a macro that could be derived using information that is already available.

2022-06-27Input: iqs7222 - correct slider event disable logicJeff LaBundy1-7/+9
If a positive swipe/flick gesture is defined but the corresponding negative gesture is not, the former is inadvertently disabled. Fix this by gently refactoring the logic responsible for disabling all gestures by default. As part of this change, make the code a bit simpler by eliminating a superfluous conditional check. If a slider event does not define an enable control, the second term of the bitwise AND operation is simply 0xFFFF.

2022-05-31Input: mtk-pmic-keys - move long press debounce mask to mtk_pmic_regsAngeloGioacchino Del Regno1-6/+9
As the second and last step of preparation to add support for more PMICs in this driver, move the long press debounce mask to struct mtk_pmic_regs and use that in mtk_pmic_keys_lp_reset_setup() instead of directly using the definition. While at it, remove the definition for MTK_PMIC_RST_DU_SHIFT as we are able to calculate it dynamically and spares us some unnecessary new definitions around for future per-PMIC variations of RST_DU_MASK. Lastly, it was necessary to change the function signature of mtk_pmic_keys_lp_reset_setup() to now pass a pointer to the main mtk_pmic_regs structure, since that's where the reset debounce mask now resides.

2022-05-22afs: Fix afs_getattr() to refetch file status if callback break occurredDavid Howells1-1/+13
If a callback break occurs (change notification), afs_getattr() needs to issue an FS.FetchStatus RPC operation to update the status of the file being examined by the stat-family of system calls. Fix afs_getattr() to do this if AFS_VNODE_CB_PROMISED has been cleared on a vnode by a callback break. Skip this if AT_STATX_DONT_SYNC is set. This can be tested by appending to a file on one AFS client and then using "stat -L" to examine its length on a machine running kafs. This can also be watched through tracing on the kafs machine.

2022-05-21perf session: Fix Intel LBR callstack entries and nr print messageChengdong Li1-5/+21
When generating callstack information from branch_stack(Intel LBR), the actual number of callstack entry should be bigger than the number of branch_stack, for example: branch_stack records: B() -> C() A() -> B() converted callstack records should be: C() B() A() though, the number of callstack equals to the number of branch stack plus 1.

After installing clang, testcase passes. Reason on why subtest failure happens though logs has proper debug information: Main function __test__bpf calls test_llvm__fetch_bpf_obj by passing 4th argument as true ( 4th arguments maps to parameter "force" in test_llvm__fetch_bpf_obj ). But this will cause test_llvm__fetch_bpf_obj to skip the check for clang/llvm.

for_each_shell_test() is already strict in expecting tests to be files and executable. It is sometimes possible when it iterates over all files that it finds one that is executable and lacks a newline character. When this happens the loop never terminates as it doesn't check for EOF.

"perf all PMU test" picks the input events from "perf list --raw-dump pmu" list and runs "perf stat -e" for each of the event in the list. In case of powerpc, the PowerVM environment supports events from hv_24x7 and hv_gpci PMU which is of example format like below: - hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/ - hv_gpci/event,partition_id=?/ The value for "?" needs to be filled in depending on system and respective event. CPM_ADJUNCT_INST needs have core value and domain value. hv_gpci event needs partition_id. Similarly, there are other events for hv_24x7 and hv_gpci having "?" in event format. Hence skip these events on powerpc platform since values like partition_id, domain is specific to system and event.

Before sending a MSI the hardware writes information pertinent to the interrupt cause to a memory location pointed by SMTICL register. This memory holds three double words where the least significant bit tells whether the interrupt cause of master/target/error is valid. The driver does not use this but we need to set it up because otherwise it will perform DMA write to the default address (0) and this will cause an IOMMU fault such as below: DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Write] Request device [00:12.0] PASID ffffffff fault addr 0 [fault reason 05] PTE Write access is not set To prevent this from happening, provide a proper DMA buffer for this that then gets mapped by the IOMMU accordingly.
