2023-06-19mmc: sunxi: fix deferred probingSergey Shtylyov
The driver overrides the error codes and IRQ0 returned by platform_get_irq() to -EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe permanently instead of the deferred probing. Switch to propagating the error codes upstream. Since commit ce753ad1549c ("platform: finally disallow IRQ0 in platform_get_irq() and its ilk") IRQ0 is no longer returned by those APIs, so we now can safely ignore it...

2023-06-19mmc: mmci: Retry the busy start conditionLinus Walleij
This makes the ux500 ->busy_complete() callback re-read the status register 10 times while waiting for the busy signal to assert in the status register. If this does not happen, we bail out regarding the command completed already, i.e. before we managed to start to check the busy status. There is a comment in the code about this, let's just implement it to be certain that we can catch this glitch if it happens.

2023-06-19mmc: mmci: Make busy complete state machine explicitLinus Walleij
This refactors the ->busy_complete() callback currently only used by Ux500 and STM32 to handle busy detection on hardware where one and the same IRQ is fired whether we get a start or an end signal on busy detect. The code is currently using the cached status from the command IRQ in ->busy_status as a state to select what to do next: if this state is non-zero we are waiting for IRQs and if it is zero we treat the state as the starting point for a busy detect wait cycle. Make this explicit by creating a state machine where the ->busy_complete callback moves between three states. The Ux500 busy detect code currently assumes this order: we enable the busy detect IRQ, get a busy start IRQ, then a busy end IRQ, and then we clear and mask this IRQ and proceed. We insert debug prints for unexpected states. This works as before on most cards, however on a problematic card that is not working with busy detect, and which I have been debugging, the following happens a lot: [ 3.380554] mmci-pl18x 80005000.mmc: no busy signalling in time [ 3.387420] mmci-pl18x 80005000.mmc: no busy signalling in time [ 3.394561] mmci-pl18x 80005000.mmc: lost busy status when waiting for busy start IRQ This probably means that the busy detect start IRQ has already occurred when we start executing the ->busy_complete() callbacks, and the busy detect end IRQ is counted as the start IRQ, and this is what is causing the card to not be detected properly.

2023-06-19mmc: mmci: Break out error check in busy detectLinus Walleij
The busy detect callback for Ux500 checks for an error in the status in the first if() clause. The only practical reason is that if an error occurs, the if()-clause is not executed, and the code falls through to the last if()-clause if (host->busy_status) which will clear and disable the irq. Make this explicit instead: it is easier to read.

2023-06-19mmc: mmci: Unwind big if() clauseLinus Walleij

2023-06-19mmc: mmci: Clear busy_status when starting commandLinus Walleij
If we are starting a command which can generate a busy response, then clear the variable host->busy_status if the variant is using a ->busy_complete callback. We are lucky that the member is zero by default and hopefully always gets cleared in the ->busy_complete callback even on errors, but it's just fragile so make sure it is always initialized to zero.

2023-06-19EDAC/amd64: Cache and use GPU node mapYazen Ghannam
AMD systems have historically provided an "AMD Node ID" that is a unique identifier for each die in a multi-die package. This was associated with a unique instance of the AMD Northbridge on a legacy system. And now it is associated with a unique instance of the AMD Data Fabric on modern systems. Each instance is referred to as a "Node"; this is an AMD-specific term not to be confused with NUMA nodes. The data fabric provides a number of interfaces accessible through a set of functions in a single PCI device. There is one PCI device per Data Fabric (AMD Node), and multi-die systems will see multiple such PCI devices. The AMD Node ID matches a Node's position in the PCI hierarchy. For example, the Node 0 is accessed using the first PCI device, Node 1 is accessed using the second, and so on. A logical CPU can find its AMD Node ID using CPUID. Furthermore, the AMD Node ID is used within the hardware fabric, so it is not purely a logical value. Heterogeneous AMD systems, with a CPU Data Fabric connected to GPU data fabrics, follow a similar convention. Each CPU and GPU die has a unique AMD Node ID value, and each Node ID corresponds to PCI devices in sequential order. However, there are two caveats: 1) GPUs are not x86, and they don't have CPUID to read their AMD Node ID like on CPUs. This means the value is more implicit and based on PCI enumeration and hardware-specifics. 2) There is a gap in the hardware values for AMD Node IDs. Values 0-7 are for CPUs and values 8-15 are for GPUs. For example, a system with one CPU die and two GPUs dies will have the following values: CPU0 -> AMD Node 0 GPU0 -> AMD Node 8 GPU1 -> AMD Node 9 EDAC is the only subsystem where this has a practical effect. Memory errors on AMD systems are commonly reported through MCA to a CPU on the local AMD Node. The error information is passed along to EDAC where the AMD EDAC modules use the AMD Node ID of reporting logical CPU to access AMD Node information. However, memory errors from a GPU die will be reported to the CPU die. Therefore, the logical CPU's AMD Node ID can't be used since it won't match the AMD Node ID of the GPU die. The AMD Node ID of the GPU die is provided as part of the MCA information, and the value will match the hardware enumeration (e.g. 8-15). Handle this situation by discovering GPU dies the same way as CPU dies in the AMD NB code. But do a "node id" fixup in AMD64 EDAC where it's needed. The GPU data fabrics provide a register with the base AMD Node ID for their local "type", i.e. GPU data fabric. This value is the same for all fabrics of the same type in a system. Read and cache the base AMD Node ID from one of the GPU devices during module initialization. Use this to fixup the "node id" when reporting memory errors at runtime.

2023-06-19wifi: iwlwifi: add some FW misbehaviour check infrastructureJohannes Berg
When the firmware misbehaves (according to the driver), we often either ignore that, or WARN_ON, which is very noisy but doesn't really help. Add a little helper macro IWL_FW_CHECK() that can be used in place of WARN_ON() in conditions, and make it take a message that's printed in this case. We can also add more behaviour to this in the future.
