Any access over serial console would involve a lot of TX and RX register accesses (and few others), so these MMIO read/write trace events in these drivers cause a lot of unwanted noise because of the high frequency of such operations and it is not very useful tracing these events for such drivers. Given we want to enable these trace events on development devices (maybe not production devices) where performance also really matters so that we don't regress other components by wasting CPU cycles and memory collecting these traces, it makes more sense to disable these traces from such drivers. Also another reason to disable these traces would be to prevent recursive tracing when we display the trace buffer containing these MMIO trace events since writing onto serial console would further record MMIO traces.

It introduces support for the SCM wrapper driver to vote for interconnect bandwidth for operations that needs bandwidth to the crypto engine. This ensures both performance and guards against issues caused by lacking votes for this path. The socinfo driver gains knowledge about the SC7180P SoC. It contains a range of fixes for spelling mistakes, refcount leaks in various drivers and removes some redundant code from the apr remove path. The SCM DT bindings are updated to declare support for QCS404, SM6125 and SDX65.

The BWMON can be configured to monitor the data throuhput between memory and other subsytems. The throughput is measured within specified sampling window and is used to vote for corresponding interconnect bandwidth. Current implementation brings support for BWMON v4, used for example on SDM845 to measure bandwidth between CPU (gladiator_noc) and Last Level Cache (memnoc). Usage of this BWMON allows to remove fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high memory throughput even with lower CPU frequencies. The driver was tested on SDM845.

From printouts I see that at bootup the function is called with an id of "lnbclka2" which is 8 bytes big. Previously all 8 bytes of this string were copied to the destination. Now only 7 bytes will be copied since strscpy_pad() saves a byte for '\0' termination. We don't need the '\0' termination in the destination. Let's go back to strncpy(). According to the warning: If a caller is using non-NUL-terminated strings, strncpy() can still be used, but destinations should be marked with the __nonstring attribute to avoid future compiler warnings. ...so we'll do that. While we're at it, let's change the query array to use "sizeof(ent->id)" so it can't possibly go out of sync with our later copy.

Thus we just search the device tree for the corresponding device, map its memory to read the id and then unmap it again. Because it is likely that the offset within the fuses is dependent on the SoC, we need a per SoC data. Also, the compatible string is different among the SoCs.

| | * | soc: fsl: guts: use of_root instead of own referenceMichael Walle2022-06-271-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is already a global of_root reference. Use that instead of getting one on our own. We don't need to care about the reference count either this way. Signed-off-by: Michael Walle <michael@walle.cc> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the last global static variable. Drop it and allocate the memory on the heap instead.

| | * | soc: fsl: guts: embed fsl_guts_get_svr() in probe()Michael Walle2022-06-271-31/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the reading of the SVR into the probe function as fsl_guts_get_svr() is the only user of the static guts variable and this lets us drop that as well as the malloc() for this variable. Also, we can unmap the memory region after we accessed it, which will simplify error handling later.

| | * | soc: fsl: guts: remove module_exit() and fsl_guts_remove()Michael Walle2022-06-271-14/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver will never be unloaded. Firstly, it is not available as a module, but more importantly, other drivers will depend on this one to apply possible chip errata.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If both the model and the compatible properties are missing, then machine will not be set. Initialize it with NULL.
