2020-02-04.travis.yml: single thread build-tcgAlex Bennée1-2/+2
I've theorised that a parallel build-tcg is somehow getting confused when two fedora-30 based cross compilers attempt to build at the same time. From one data-point so far this may fix the problem although the plugins job runs quite close to timeout.

2020-02-04.travis.yml: drop cris-linux-user from the plugins testAlex Bennée1-1/+2
While it shouldn't cause problems we will never get useful information from cris as it has yet to be converted to the common translator loop. It also causes the Travis CI to fail for weird reasons which I have so far been unable to replicate on a normal Xenial system.

iotest 147 and 205 have recently been marked as "NBD-only", so they are currently simply skipped and thus can be removed. iotest 129 occasionally fails in the gitlab-CI, and according to Max, there are some known issues with this test (see for example this URL: https://lists.nongnu.org/archive/html/qemu-block/2019-06/msg00499.html ), so for the time being, let's disable it until the problems are fixed. The iotests 040, 127, 203 and 256 are scheduled to become part of "make check-block", so we also do not have to test them seperately here anymore.

2020-02-03docs/sphinx: Add new hxtool Sphinx extensionPeter Maydell2-1/+212
Some of our documentation includes sections which are created by assembling fragments of texinfo from a .hx source file into a .texi file, which is then included from qemu-doc.texi or qemu-img.texi. For Sphinx, rather than creating a file to include, the most natural way to handle this is to have a small custom Sphinx extension which reads the .hx file and process it. So instead of: * makefile produces foo.texi from foo.hx * qemu-doc.texi says '@include foo.texi' we have: * qemu-doc.rst says 'hxtool-doc:: foo.hx' * the Sphinx extension for hxtool has code that runs to handle that Sphinx directive which reads the .hx file and emits the appropriate documentation contents This is pretty much the same way the kerneldoc extension works right now. It also has the advantage that it should work for third-party services like readthedocs that expect to build the docs directly with sphinx rather than by invoking our makefiles. In this commit we implement the hxtool extension. Note that syntax errors in the rST fragments will be correctly reported to the user with the filename and line number within the hx file.

2020-02-03hxtool: Support SRST/ERST directivesPeter Maydell1-1/+32
We want to add support for including rST document fragments in our .hx files, in the same way we currently have texinfo fragments. These will be delimited by SRST and ERST directives, in the same way the texinfo is delimited by STEXI/ETEXI. The rST fragments will not be extracted by the hxtool script, but by a different mechanism, so all we need to do in hxtool is have it ignore all the text inside a SRST/ERST section, with suitable error-checking for mismatched rST-vs-texi fragment delimiters. The resulting effective state machine has only three states: * flag = 0, rstflag = 0 : reading section for C output * flag = 1, rstflag = 0 : reading texi fragment * flag = 0, rstflag = 1 : reading rST fragment and flag = 1, rstflag = 1 is not possible. Using two variables makes the parallel between the rST handling and the texi handling clearer; in any case all this code will be deleted once we've converted entirely to rST.

2020-02-03Makefile: Ensure we don't run Sphinx in parallel for manpagesPeter Maydell2-7/+46
Sphinx will corrupt its doctree cache if we run two copies of it in parallel. In commit 6bda415c10d966c8d3 we worked around this by having separate doctrees for 'html' vs 'manpage' runs. However now that we have more than one manpage produced from a single manual we can run into this again when trying to produce the two manpages. Use the trick described in 'Atomic Rules in GNU Make' https://www.cmcrossroads.com/article/atomic-rules-gnu-make to ensure that we only run the Sphinx manpage builder once for each manual, even if we're producing several manpages. This fixes doctree corruption in parallel builds and also avoids pointlessly running Sphinx more often than we need to. (In GNU Make 4.3 there is builtin support for this, via the "&:" syntax, but we can't wait for that to be available in all the distros we support...) The generic "one invocation for multiple output files" machinery is provided as a macro named 'atomic' in rules.mak; we then wrap this in a more specific macro for defining the rule and dependencies for the manpages in a Sphinx manual, to avoid excessive repetition.

2020-02-03tests: Silence various warnings with pseriesGreg Kurz4-5/+16
Some default features of the pseries machine are only available with KVM. Warnings are printed when the pseries machine is used with another accelerator: qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on qemu-system-ppc64: warning: Firmware Assisted Non-Maskable Interrupts(FWNMI) not supported in TCG This is annoying for CI since it usually runs without KVM. We already disable features that emit similar warnings thanks to properties of the pseries machine, but this is open-coded in various places. Consolidate the set of properties in a single place. Extend it to silence the above warnings. And use it in the various tests that start pseries machines.

This patch adds support in QEMU to handle "ibm,nmi-register" and "ibm,nmi-interlock" RTAS calls. The machine check notification address is saved when the OS issues "ibm,nmi-register" RTAS call. This patch also handles the case when multiple processors experience machine check at or about the same time by handling "ibm,nmi-interlock" call. In such cases, as per PAPR, subsequent processors serialize waiting for the first processor to issue the "ibm,nmi-interlock" call. The second processor that also received a machine check error waits till the first processor is done reading the error log. The first processor issues "ibm,nmi-interlock" call when the error log is consumed.

2020-02-03target/ppc: Build rtas error log upon an MCEAravinda Prasad4-3/+253
Upon a machine check exception (MCE) in a guest address space, KVM causes a guest exit to enable QEMU to build and pass the error to the guest in the PAPR defined rtas error log format. This patch builds the rtas error log, copies it to the rtas_addr and then invokes the guest registered machine check handler. The handler in the guest takes suitable action(s) depending on the type and criticality of the error. For example, if an error is unrecoverable memory corruption in an application inside the guest, then the guest kernel sends a SIGBUS to the application. For recoverable errors, the guest performs recovery actions and logs the error.
