The SSWI device provides supervisor-level IPI functionality for a set of HARTs on a RISC-V platform. It provides a register to set an IPI (SETSSIP) for each HART connected to the SSWI device. The patch utilizes the feature to optimize IPI handling by avoiding Linux calls into firmware runtime, thus minimizing context switching expenses and removing the dependency on sbi-ipi.

While working with the T-Head 1520 LicheePi4A SoC, certain conditions
arose that allowed me to reproduce a race issue in the sdhci code.
To reproduce the bug, you need to enable the sdio1 controller in the
device tree file
`arch/riscv/boot/dts/thead/th1520-lichee-module-4a.dtsi` as follows:
&sdio1 {
bus-width = <4>;
max-frequency = <100000000>;
no-sd;
no-mmc;
broken-cd;
cap-sd-highspeed;
post-power-on-delay-ms = <50>;
status = "okay";
wakeup-source;
keep-power-in-suspend;
};
When resetting the SoC using the reset button, the following messages
appear in the dmesg log:

command operation was in progress.

Here's what happens: the __mmc_start_request function is called with
opcode 5. Since the power to the Wi-Fi card, which resides on this SDIO
bus, is initially off after the reset, an interrupt SDHCI_INT_TIMEOUT is
triggered. Immediately after that, a second interrupt SDHCI_INT_RESPONSE
is triggered. Depending on the exact timing, these conditions can
trigger the following race problem:
1) The sdhci_cmd_irq top half handles the command as an error. It sets
host->cmd to NULL and host->pending_reset to true.
2) The sdhci_thread_irq bottom half is scheduled next and executes faster
than the second interrupt handler for SDHCI_INT_RESPONSE. It clears
host->pending_reset before the SDHCI_INT_RESPONSE handler runs.
3) The pending interrupt SDHCI_INT_RESPONSE handler gets called, triggering
a code path that prints: "mmc2: Got command interrupt 0x00000001 even
though no command operation was in progress."
To solve this issue, we need to clear pending interrupts when resetting
host->pending_reset. This ensures that after sdhci_threaded_irq restores
interrupts, there are no pending stale interrupts.
The behavior observed here is non-compliant with the SDHCI standard.
Place the code in the sdhci-of-dwcmshc driver to account for a
hardware-specific quirk instead of the core SDHCI code.

The new model is that each of the devices which utilize platform-MSI gets now its private MSI domain which is "customized" in size and with a device specific function to write the MSI message into the device. This is the same functionality as platform-MSI but it avoids all the down sides of platform MSI, i.e. the extra ID book keeping, the special data structure in the msi descriptor. Further the domains are only created when the devices are really in use, so the burden is on the usage and not on the infrastructure. Fill in the domain template and provide two functions to init/allocate and remove a per device MSI domain. Until all users and parent domain providers are converted, the init/alloc function invokes the original platform-MSI code when the irqdomain which is associated to the device does not provide MSI parent functionality yet.

Wired interrupts which are connected to a wire to MSI bridge, like MBIGEN are allocated that way. So far MBIGEN provides a regular irqdomain which then hooks backwards into the MSI infrastructure. That's an unholy mess and will be replaced with per device MSI domains which are regular MSI domains. Interrupts on MSI domains are not supported by irq_create_fwspec_mapping(), but for making the wire to MSI bridges sane it makes sense to provide a special allocation/free interface in the MSI infrastructure. That avoids the backdoors into the core MSI allocation code and just shares all the regular MSI infrastructure. Provide an optional translation callback in msi_domain_ops which can be utilized by these wire to MSI bridges. No other MSI domain should provide a translation callback. The default translation callback of the MSI irqdomains will warn when it is invoked on a non-prepared MSI domain.

Since de1ff306dcf4 ("genirq/irqdomain: Remove the param count restriction from select()"), ops->select() is called unconditionally, meaning that irqchips implementing select() now need to handle ANY as a match. Instead of adding more esoteric checks to the individual drivers, add that condition to irq_find_matching_fwspec(), and let it handle the corner case, as per the comment in the function. This restores the functionality of the above helpers.

The mechanism for allocation is: - Allocate the next free MSI descriptor index in the domain - Store the hardware interrupt number and the trigger type which was extracted by the irqdomain core from the firmware spec in the MSI descriptor device cookie so it can be retrieved by the underlying interrupt domain and interrupt chip - Use the regular MSI allocation mechanism for the newly allocated index which returns a fully initialized Linux interrupt on succes This works because: - the domains have a fixed size - each hardware interrupt is only allocated once - the underlying domain does not care about the MSI index it only cares about the hardware interrupt number and the trigger type The free function looks up the MSI index in the MSI descriptor of the provided Linux interrupt number and uses the regular index based free functions of the MSI core.
