Since on early phase of bringup, the SMU IP may be not enabled or supported. Without this, we may hit null pointer dereference on accessing smu->adev. Signed-off-by:

[Why] Warnings in the kernel are generally treated as errors. The BREAK_TO_DEBUGGER macro is not a critical error or warning, but rather intended for developer use to help investigate behavior and sequences for other issues. We do still make use of DC_ERROR/ASSERT(0) in various places in the code for things that are genuine issues. Since most developers don't actually KGDB while debugging the kernel these essentially would have no value on their own since the KGDB breakpoint wouldn't trigger - ASSERT(0) was used as a shortcut to get a stacktrace. [How] Turn it into a DRM_DEBUG_DRIVER print instead. We unfortunately lose the stacktrace, but we still do retain some of the useful debug information this offers by having at least the function and line number loggable. If KGDB is supported in the kernel this will still trigger a real breakpoint as well.

The current codebase makes use of one-element arrays in the following form: struct something { int length; u8 data[1]; }; struct something *instance; instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL); instance->length = size; memcpy(instance->data, source, size); but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. So, replace the one-element array with a flexible-array member. Also, make use of the new struct_size() helper to properly calculate the size of struct SISLANDS_SMC_SWSTATE. This issue was found with the help of Coccinelle and, audited and fixed _manually_.

Just check if it's an APU. The checks for the ppfuncs are pointless because if we don't have them we can't power up sdma anyway so we shouldn't even be in this code in the first place. I'm not sure about the in_gpu_reset check. This probably needs to be double checked. The fini logic doesn't match the init logic however with that in_gpu_reset check in place which seems odd.

[Why] In order to switch over the inbox from region4 to cw4 we need to know if the firmware is capable of properly invalidating the cache before reading the commands.

[why] DP link layer CTS specs updated to change the test parameters in test 4.2.1.1. Before it requires source to delay 400us on aux no reply. With the specs updates Errata5, it requires source to delay 3.2ms (based on LTTPR aux timeout) This causes our test to fail after updating with the latest test equipment firmware. [how] the change is to allow LTTPR 3.2ms aux timeout delay by default. And only set to 400us if LTTPR is not present. Before this piece of logic is interwined with LTTPR support. Now we will default to 3.2ms aux timeout even if LTTPR support is not enabled by driver. Signed-off-by:

[Why] Due to packing of abm_config_table, memory addresses aren't aligned to 32 bit boundary dmcub prefers. Therefore when using pointers to this structure, it's possible that dmcub will automatically align the data read from that address, yielding incorrect values. [How] Instead of packing 1 byte boundary, explicitly pack values to 4 byte boundary. Since there is a dependency on the existing iram table structure on driver side, we must copy to a second structure, which is aligned correctly, before passing to fw. Signed-off-by:
