Hello I am trying to use qemu-system-arm64 as an emulator to try out ARM assembly - things like writing code to set up the translation tables etc. For this I was looking for the memory map of the ARM virt machine. Peter Maydell, in an off-list thread, mentioned the following for the virt machine :
* a flash device at 0x0 * RAM starting at 0x40000000 The DTB can be dumped using a command line like this: $ qemu-system-aarch64 -machine type=virt -machine dumpdtb=virt.dtb -cpu cortex-a57 He mentioned that all other values like -machine gic-version= <something> etc I dont know what values can be provided for gic-version. Are the possible values documented somewhere? I am unsure what else I should specify besides GIC. Are all -machine options documented somewhere ? What is the first memory address fetched by the processor in the virt machine? (ie where should I place the first instruction of my bare metal code) Thank you, Hrishi PS: Please cc me on reply, I am not subscribed to the list
