Subject: [PATCH 1/5] vl: allow not specifying size in -m when using -M
|
|
memory-backend
|
|
|
|
Starting in QEMU 6.0's commit f5c9fcb82d ("vl: separate
|
|
qemu_create_machine", 2020-12-10), a function have_custom_ram_size()
|
|
replaced the return value of set_memory_options().
|
|
|
|
The purpose of the return value was to record the presence of
|
|
"-m size", and if it was not there, change the default RAM
|
|
size to the size of the memory backend passed with "-M
|
|
memory-backend".
|
|
|
|
With that commit, however, have_custom_ram_size() is now queried only
|
|
after set_memory_options has stored the fixed-up RAM size in QemuOpts for
|
|
"future use". This was actually the only future use of the fixed-up RAM
|
|
size, so remove that code and fix the bug.
