Kernel start address. [PATCH] perf: Get kernel start address by symbol name From: Simon Que Date: Fri Jun 13 2014 - 14:46:36 EST The function machine__get_kernel_start_addr() was taking the first symbol of kallsyms as the start address This function is executed at the address stored in LOAD_PHYSICAL_ADDR This region is only used during system start i But, as usual, they are pretty logical when you figure it out Parameters for modules which are built into the kernel The kernel_start() function calls binInstallByMask() (see "binInstallByMask and binInstallByType()") to install the microkernel and all actors that belong to the initial kernel address space It is fully generic: it is the same point that all other Linux architectures call, so we have now reached the level of generic kernel code written in C So next we save the processor ID, machine type and ATAG or DTB pointer and branch to the symbol start_kernel() As per the steps given below: zramfs is getting created with node /dev/zram0 Press and
