A strange behaviour is observed when comparing PCI hotplug in QEMU, between x86 and pseries. If you consider the following steps: - start a VM - add a PCI device via the QEMU monitor before the rtasd has started (for example starting the VM in paused state, or hotplug during FW or boot loader) - resume the VM execution The x86 kernel detects the PCI device, but the pseries one does not. This happens because the rtasd kernel worker is currently started under device_initcall, while PCI probing happens earlier under subsys_initcall. As a consequence, if we have a pending RTAS event at boot time, a message is printed and the event is dropped. This patch moves all the initialization of rtasd to arch_initcall, which is run before subsys_call: this way, logging_enabled is true when the RTAS event pops up and it is not lost anymore. The proc fs bits stay at device_initcall because they cannot be run before fs_initcall. Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> |
