2017-05-04char-socket: update local address after listenMarc-André Lureau1-0/+5
This is mainly useful to know the actual bound port when using port 0. For example, when starting qemu with socket on port 0, before: QEMU waiting for connection on: disconnected:tcp:localhost:0,server After: QEMU waiting for connection on: disconnected:tcp:localhost:32454,server Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>

This member is always filled in by the guest agent when the structure is returned, and always ignored on input (hence it can be omitted then).

into staging ppc patch queue 2017-04-26 Here's a respind of my first pull request for qemu-2.10, consisting of assorted patches which have accumulated while qemu-2.9 stabilized. Highlights are: * Rework / cleanup of the XICS interrupt controller * Substantial improvement to the 'powernv' machine type - Includes an MMIO XICS version * POWER9 support improvements - POWER9 guests with KVM - Partial support for POWER9 guests with TCG * IOMMU and VFIO improvements * Assorted minor changes There are several IPMI patches here that aren't usually in my area of maintenance, but there isn't a regular maintainer and these patches are for the benefit of the powernv machine type. This pull request supersedes my 2017-04-26 pull request. This new set fixes a bug in one of the aforementioned IPMI patches which caused clang sanitizer failures (and may have crashed on some libc / host versions). # gpg: Signature made Wed 26 Apr 2017 07:58:10 BST # 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-2.10-20170426: (48 commits) MAINTAINERS: Remove myself from e500 target/ppc: Style fixes e500,book3s: mfspr 259: Register mapped/aliased SPRG3 user read target/ppc: Flush TLB on write to PIDR spapr-cpu-core: Release ICPState object during CPU unrealization ppc/pnv: generate an OEM SEL event on shutdown ppc/pnv: add initial IPMI sensors for the BMC simulator ppc/pnv: populate device tree for IPMI BT devices ppc/pnv: populate device tree for serial devices ppc/pnv: populate device tree for RTC devices ppc/pnv: scan ISA bus to populate device tree ppc/pnv: enable only one LPC bus ppc/pnv: Add support for POWER8+ LPC Controller spapr: remove the 'nr_servers' field from the machine target/ppc: Fix size of struct PPCElfPrstatus ipmi: introduce an ipmi_bmc_gen_event() API ipmi: introduce an ipmi_bmc_sdr_find() API ipmi: provide support for FRUs ipmi: use a file to load SDRs ppc: add IPMI support ...

2017-04-26e500,book3s: mfspr 259: Register mapped/aliased SPRG3 user readBernhard Kaindl1-0/+10
This patch registers mfspr 259 for Book3S and e500 family cores following this research: mfspr 259 provides read-only mapped user access to SPRG3(SPR 275) according to: - PowerISA 2.02, Book III (documents implementation starting with POWER4+ @ p20) - IBM PowerPC 970MP RISC Microprocessor User's Manual v2.1, page 48 - Amit Singh: "Mac OS X Internals: A Systems Approach" on 970 and 970FX cores: He demonstrates mfspr 259 reading TLS data from Mac OS X on G5 on page 588 - NXP documents it in the Core Reference Manuals of: e500, e500mc and e5500 - getcpu() of the 32 & 64-bit Book3S Linux vDSOs use it to read the core number mfspr 259 does not appear to be implemented in these cores according to: - 74xx series: MPC7410/MPC7400 and MPC7450 RISC Microprocessor Reference Manuals - 4xx series: PPC440 Processor User's Manual, Revision 1.09 by AMCC - 750 series: IBM PowerPC 750CL RISC Microprocessor User's Manual - e200 series: e200z4 Power Architectureâ Core Reference Manual Implementation: gen_spr_usprg3() is called from init_proc_book3s_common() (covers the 970 and POWER cores) and init_proc_e500() (covers the e500 family) to register spr_read_ureg() in the same way which it already provides the mapped SPR access for SPR_USPRG4-7 in gen_spr_usprgh() for cores which have the same read-only mapped SPRG register access for SPRG4-7. Verified using Linux by pinning a thread to a core and checking sched_getcpu() using qemu-system-ppc64 -M pseries -cpu POWER8 using MTTCG on a x86_64 host.

2017-04-26target/ppc: Flush TLB on write to PIDRSuraj Jitindar Singh3-2/+17
The PIDR (process id register) is used to store the id of the currently running process, which is used to select the process table entry used to perform address translation. This means that when we write to this register all the translations in the TLB become outdated as they are for a previously running process. Thus when this register is written to we need to invalidate the TLB entries to ensure stale entries aren't used to to perform translation for the new process, which would result in at best segfaults or alternatively just random memory being accessed.
