iwlwifi: mvm: Add mem debugfs entry
In order to access cached/paged memory, there are a couple of firmware commands (one for UMAC and one for LMAC) that let the host access memory and registers indirectly. Since this is done by the firmware on behalf of the host, even if memory is paged out or cached, the host will retrieve the memory as the firmware sees it (paged out memory will get paged in). Export this mechanism via a debugfs entry for both read and write access. WARNING: This mechanism has no protections at all. Invalid addresses may crash or hang the firmware. Writing to arbitrary memory also comes with no guarantees. Signed-off-by: Ido Yariv <idox.yariv@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
