2017-03-03vl: disable default cdrom when using explicitely scsi-hdHervé Poussineau
In commit af6bf1328ef90fae617857c02697e0174b84d596 (May 2011), ide-hd, ide-cd and scsi-cd have been added to disable default cdrom, "or else you can't put one on secondary master without -nodefaults". Make it the same for scsi-hd, so you can put one on scsi-id 2 without using -nodefaults. scsi-hd has probably been forgotten, as it has been added in the preceding commit (b443ae67130d32ad06b06fc9aa6d04d05ccd93ce). Affected users are the ones using a machine with SCSI devices and start QEMU with -device scsi-hd but without -device scsi-cd or -cdrom In that case, the default cdrom device will disappear instead of being empty.

2017-03-03memory: Introduce DEVICE_HOST_ENDIAN for ram deviceYongji Xie
At the moment ram device's memory regions are DEVICE_NATIVE_ENDIAN. It's incorrect. This memory region is backed by a MMIO area in host, so the uint64_t data that MemoryRegionOps read from/write to this area should be host-endian rather than target-endian. Hence, current code does not work when target and host endianness are different which is the most common case on PPC64. To fix it, this introduces DEVICE_HOST_ENDIAN for the ram device. This has been tested on PPC64 BE/LE host/guest in all possible combinations including TCG.

2017-03-03KVM: use KVM_CAP_IMMEDIATE_EXITPaolo Bonzini
The purpose of the KVM_SET_SIGNAL_MASK API is to let userspace "kick" a VCPU out of KVM_RUN through a POSIX signal. A signal is attached to a dummy signal handler; by blocking the signal outside KVM_RUN and unblocking it inside, this possible race is closed: VCPU thread service thread -------------------------------------------------------------- check flag set flag raise signal (signal handler does nothing) KVM_RUN However, one issue with KVM_SET_SIGNAL_MASK is that it has to take tsk->sighand->siglock on every KVM_RUN. This lock is often on a remote NUMA node, because it is on the node of a thread's creator. Taking this lock can be very expensive if there are many userspace exits (as is the case for SMP Windows VMs without Hyper-V reference time counter). KVM_CAP_IMMEDIATE_EXIT provides an alternative, where the flag is placed directly in kvm_run so that KVM can see it: VCPU thread service thread -------------------------------------------------------------- raise signal signal handler set run->immediate_exit KVM_RUN check run->immediate_exit The previous patches changed QEMU so that the only blocked signal is SIG_IPI, so we can now stop using KVM_SET_SIGNAL_MASK and sigtimedwait if KVM_CAP_IMMEDIATE_EXIT is available. On a 14-VCPU guest, an "inl" operation goes down from 30k to 6k on an unlocked (no BQL) MemoryRegion, or from 30k to 15k if the BQL is involved. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2017-03-03spapr: Small cleanup of PPC MMU enumsSam Bobroff
The PPC MMU types are sometimes treated as if they were a bit field and sometime as if they were an enum which causes maintenance problems: flipping bits in the MMU type (which is done on both the 1TB segment and 64K segment bits) currently produces new MMU type values that are not handled in every "switch" on it, sometimes causing an abort(). This patch provides some macros that can be used to filter out the "bit field-like" bits so that the remainder of the value can be switched on, like an enum. This allows removal of all of the "degraded" types from the list and should ease maintenance.

The (paravirtual) PCI host bridge on the 'pseries' machine in most regards acts like a regular PCI bus, rather than a PCIe bus. Despite this, though, it does allow access to the PCIe extended config space. We already implemented the RTAS methods to allow this access.. but forgot to put the markers into the device tree so that guest's know it is there. This adds them in. With this, a pseries guest is able to view extended config space on (for example an e1000e device. This should be enough to allow guests to use at least some PCIe devices.

2017-03-03target/ppc: Move no-execute and guarded page checking into new functionSuraj Jitindar Singh
A pte entry has bit fields which can be used to make a page no-execute or guarded, if either of these bits are set then an instruction access to this page will fail. Currently these bits are checked with the pp_prot function however the ISA specifies that the access authority controlled by the key-pp value pair should only be checked on an instruction access after the no-execute and guard bits have already been verified to permit the access. Move the no-execute and guard bit checking into a new separate function. Note that we can remove the check for the no-execute bit in the slb entry since this check was already performed above when we obtained the slb entry. In the event that the no-execute or guard bits are set, an ISI should be generated with the SRR1_NOEXEC_GUARD (0x10000000) bit set in srr1. Add a define for this for clarity.

2017-03-03target/ppc: Add Instruction Authority Mask Register CheckSuraj Jitindar Singh
The instruction authority mask register (IAMR) can be used to restrict permissions for instruction fetch accesses on a per key basis for each of 32 different key values. Access permissions are derived based on the specific key value stored in the relevant page table entry. The IAMR was introduced in, and is present in processors since, POWER8 (ISA v2.07). Thus introduce a function to check access permissions based on the pte key value and the contents of the IAMR when handling a page fault to ensure sufficient access permissions for an instruction fetch. A hash pte contains a key value in bits 2:3|52:54 of the second double word of the pte, this key value gives an index into the IAMR which contains 32 2-bit access masks. If the least significant bit of the 2-bit access mask corresponding to the given key value is set (IAMR[key] & 0x1 == 0x1) then the instruction fetch is not permitted and an ISI is generated accordingly. While we're here, add defines for the srr1 bits to be set for the ISI for clarity. e.g. pte: dw0 [XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX] dw1 [XX01XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX010XXXXXXXXX] ^^ ^^^ key = 01010 (0x0a) IAMR: [XXXXXXXXXXXXXXXXXXXX01XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX] ^^ Access mask = 0b01 Test access mask: 0b01 & 0x1 == 0x1 Least significant bit of the access mask is set, thus the instruction fetch is not permitted. We should generate an instruction storage interrupt (ISI) with bit 42 of SRR1 set to indicate access precluded by virtual page class key protection.

2017-03-03target/ppc: Don't gen an SDR1 on POWER9 and rework register creationSuraj Jitindar Singh
POWER9 doesn't have a storage description register 1 (SDR1) which is used to store the base and size of the hash table. Thus we don't need to generate this register on the POWER9 cpu model. While we're here, the register generation code for 970, POWER5+, POWER<7/8/9> in general is a mess where we call a generic function from a model specific function which then attempts to call model specific functions, so rework this for readability. We update ppc_cpu_dump_state so that "info registers" will only display the value of sdr1 if the register has been generated. As mentioned above the register generation for the pcc->init_proc function for 970, POWER5+, POWER7, POWER8 and POWER9 has been reworked for improved clarity. Instead of calling init_proc_book3s_64 which then attempts to generate the correct registers through a mess of if statements, we remove this function and instead call the appropriate register generation functions directly. This follows the register generation model used for earlier cpu models (pre-970) whereby cpu specific registers are generated directly in the init_proc function and makes it easier to add/remove specific registers for new cpu models.

2017-03-03target/ppc: Add patb_entry to sPAPRMachineStateSuraj Jitindar Singh
ISA v3.00 adds the idea of a partition table which is used to store the address translation details for all partitions on the system. The partition table consists of double word entries indexed by partition id where the second double word contains the location of the process table in guest memory. The process table is registered by the guest via a h-call. We need somewhere to store the address of the process table so we add an entry to the sPAPRMachineState struct called patb_entry to represent the second doubleword of a single partition table entry corresponding to the current guest. We need to store this value so we know if the guest is using radix or hash translation and the location of the corresponding process table in guest memory. Since we only have a single guest per qemu instance, we only need one entry. Since the partition table is technically a hypervisor resource we require that access to it is abstracted by the virtual hypervisor through the get_patbe() call. Currently the value of the entry is never set (and thus defaults to 0 indicating hash), but it will be required to both implement POWER9 kvm support and tcg radix support. We also add this field to be migrated as part of the sPAPRMachineState as we will need it on the receiving side as the guest will never tell us this information again and we need it to perform translation.

A couple of tests for the work-in-progress 'powernv' machine type attempt to test on POWER9 CPUs. However the POWER9 CPU support is incomplete and this doesn't really work. In particular the firmware image we have currently assumes the presence of the SDR1 register, which no longer exists on POWER9. We only got away with this so far, because of a different bug which added SDR1 to POWER9 even though it shouldn't be there. For now, remove POWER9 testing of powernv, POWER8 testing will do for now until the POWER9 support is more complete. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

Add an entry for the POWER9/ISAv3.00 logical pvr which represents a processor running with support for logical pvr 0x0f000005. A processor running in this mode should have PCR_COMPAT_3_00 set in the pcr (if available in pcr_mask) and should have PCR_COMPAT_3_00 in pcr_supported to indicate that it is capable of running in this compat mode. Also add PCR_COMPAT_3_00 to the bits which must be set for all previous compat modes. Since no processor models contain this bit yet in pcr_mask it will never be set, but this ensures we don't forget to in the future.

into staging ppc patch queue for 2017-03-01 I was hoping to get this pull request squeezed in before the soft freeze, but I ran into some difficulties during testing. Everything here was at least posted before the soft freeze, so I'm hoping we can still merge it for 2.9. The biggest things here are: * Cleanups to handling of hashed page tables, that will make adding support for the POWER9 MMU easier * Cleanups to the XICS interrupt controller that will make implementing the powernv machine easier * TCG implementation of extended overflow and carry handling for POWER9 It also includes: * Increasing the CPU limit for pseries to 1024 vCPUs * Generating proper OF node names in qemu (making hotplug and coldplug logic closer together) # gpg: Signature made Wed 01 Mar 2017 04:43:06 GMT # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.9-20170301: (50 commits) Add PowerPC 32-bit guest memory dump support ppc/xics: rename 'ICPState *' variables to 'icp' ppc/xics: move InterruptStatsProvider to the sPAPR machine ppc/xics: move ics-simple post_load under the machine ppc/xics: remove the XICSState classes ppc/xics: export the XICS init routines ppc/xics: move the ICP array under the sPAPR machine ppc/xics: register the reset handler of ICP objects ppc/xics: simplify spapr_dt_xics() interface ppc/xics: use the QOM interface to grab an ICP ppc/xics: move the cpu_setup() handler under the ICPState class ppc/xics: simplify the cpu_setup() handler ppc/xics: move kernel_xics_fd out of KVMXICSState ppc/xics: extend the QOM interface to handle ICPs ppc/xics: remove the XICS list of ICS ppc/xics: register the reset handler of ICS objects ppc/xics: remove xics_find_source() ppc/xics: use the QOM interface to resend irqs ppc/xics: use the QOM interface to get irqs ppc/xics: use the QOM interface under the sPAPR machine ...
