2023-09-18platform/x86: intel_scu_ipc: Fail IPC send if still busyStephen Boyd1-12/+28
It's possible for interrupts to get significantly delayed to the point that callers of intel_scu_ipc_dev_command() and friends can call the function once, hit a timeout, and call it again while the interrupt still hasn't been processed. This driver will get seriously confused if the interrupt is finally processed after the second IPC has been sent with ipc_command(). It won't know which IPC has been completed. This could be quite disastrous if calling code assumes something has happened upon return from intel_scu_ipc_dev_simple_command() when it actually hasn't. Let's avoid this scenario by simply returning -EBUSY in this case. Hopefully higher layers will know to back off or fail gracefully when this happens. It's all highly unlikely anyway, but it's better to be correct here as we have no way to know which IPC the status register is telling us about if we send a second IPC while the previous IPC is still processing.

intel_scu_ipc_dev_simple_command() Andy discovered this bug during patch review. The 'scu' argument to this function shouldn't be overridden by the function itself. It doesn't make any sense. Looking at the commit history, we see that commit f57fa18583f5 ("platform/x86: intel_scu_ipc: Introduce new SCU IPC API") removed the setting of the scu to ipcdev in other functions, but not this one. That was an oversight. Remove this line so that we stop overriding the scu instance that is used by this function.

2023-09-18platform/x86: intel_scu_ipc: Check status upon timeout in ↵Stephen Boyd1-2/+4
ipc_wait_for_interrupt() It's possible for the completion in ipc_wait_for_interrupt() to timeout, simply because the interrupt was delayed in being processed. A timeout in itself is not an error. This driver should check the status register upon a timeout to ensure that scheduling or interrupt processing delays don't affect the outcome of the IPC return value. CPU0 SCU ---- --- ipc_wait_for_interrupt() wait_for_completion_timeout(&scu->cmd_complete) [TIMEOUT] status[IPC_STATUS_BUSY]=0 Fix this problem by reading the status bit in all cases, regardless of the timeout. If the completion times out, we'll assume the problem was that the IPC_STATUS_BUSY bit was still set, but if the status bit is cleared in the meantime we know that we hit some scheduling delay and we should just check the error bit.

2023-09-18platform/x86: intel_scu_ipc: Check status after timeout in busy_loop()Stephen Boyd1-11/+8
It's possible for the polling loop in busy_loop() to get scheduled away for a long time. status = ipc_read_status(scu); // status = IPC_STATUS_BUSY <long time scheduled away> if (!(status & IPC_STATUS_BUSY)) If this happens, then the status bit could change while the task is scheduled away and this function would never read the status again after timing out. Instead, the function will return -ETIMEDOUT when it's possible that scheduling didn't work out and the status bit was cleared. Bit polling code should always check the bit being polled one more time after the timeout in case this happens. Fix this by reading the status once more after the while loop breaks. The readl_poll_timeout() macro implements all of this, and it is shorter, so use that macro here to consolidate code and fix this. There were some concerns with using readl_poll_timeout() because it uses timekeeping, and timekeeping isn't running early on or during the late stages of system suspend or early stages of system resume, but an audit of the code concluded that this code isn't called during those times so it is safe to use the macro.

2023-08-25Fix nomenclature for USB and PCI wireless devicesAlan Stern1-1/+1
A mouse that uses a USB connection is called a "USB mouse" device (or "USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi adapter that connects to the host computer via USB is a "USB wireless" device, not a "wireless USB" device. (The latter term more properly refers to a defunct Wireless USB specification, which described a technology for sending USB protocol messages over an ultra wideband radio link.) Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a "PCIe wireless" device, not a "wireless PCIe" device. Rephrase the text in the kernel source where the word ordering is wrong.
