[PATCH for-6.0 9/9] spapr: spapr_drc_attach() cannot fail

All users are passing &error_abort already. Document the fact that spapr_drc_attach() should only be passed a free DRC, which is supposedly the case if appropriate checking is done earlier. Signed-off-by: Greg Kurz --- include/hw/ppc/spapr_drc.h | 8 +++- hw/ppc/spapr.c | 6 +++--

[PATCH for-6.0 4/9] spapr: Set compat mode in spapr_reset_vcpu()

When it comes to resetting the compat mode of the vCPUS, there are two situations to consider: (1) machine reset should set the compat mode back to the machine default, ie. spapr->max_compat_pvr (2) hot plugged vCPUs should set their compat mode to mach the boot vCPU, ie. POWERPC_CPU(first_

[PATCH for-6.0 8/9] spapr: Do TPM proxy hotplug sanity checks at pre-plug

There can be only one TPM proxy at a time. This is currently checked at plug time. But this can be detected at pre-plug in order to error out earlier. This allows to get rid of error handling in the plug handler. Signed-off-by: Greg Kurz --- hw/ppc/spapr.c | 23 ++- 1 file c

[PATCH for-6.0 3/9] spapr: Fix pre-2.10 dummy ICP hack

[PATCH for-6.0 7/9] spapr: Do PHB hoplug sanity check at pre-plug

We currently detect that a PHB index is already in use at plug time. But this can be decteted at pre-plug in order to error out earlier. This allows to pass &error_abort to spapr_drc_attach() and to end up with a plug handler that doesn't need to report errors anymore. Signed-off-by: Greg Kurz -

[PATCH for-6.0 1/9] spapr: Do PCI device hotplug sanity checks at pre-plug only

The PHB acts as the hotplug handler for PCI devices. It does some sanity checks on DR enablement, PCI bridge chassis numbers and multifunction. These checks are currently performed at plug time, but they would best sit in a pre-plug handler in order to error out as early as possible. Create a spap

[PATCH for-6.0 5/9] spapr: Simplify error path of spapr_core_plug()

spapr_core_pre_plug() already guarantees that the slot for the given core ID is available. It is thus safe to assume that spapr_find_cpu_slot() returns a slot during plug. Turn the error path into an assertion. It is also safe to assume that no device is attached to the corresponding DRC and that s

[PATCH for-6.0 2/9] spapr: Do NVDIMM/PC-DIMM device hotplug sanity checks at pre-plug only

Pre-plug of a memory device, be it an NVDIMM or a PC-DIMM, ensures that the memory slot is available and that addresses don't overlap with existing memory regions. The corresponding DRCs in the LMB and PMEM namespaces are thus necessarily attachable at plug time. Pass &error_abort to spapr_drc_att

[PATCH for-6.0 0/9] spapr: Perform hotplug sanity checks at pre-plug

Igor recently suggested that instead of failing in spapr_drc_attach() at plug time we should rather check that the DRC is attachable at pre-plug time. This allows to error out before the hot-plugged device is even realized and to come up with simpler plug callbacks. sPAPR currently supports hotplu
