2022-06-09hw/cxl: Make the CXL fixed memory window setup a machine parameter.Jonathan Cameron
Paolo Bonzini requested this change to simplify the ongoing effort to allow machine setup entirely via RPC. Includes shortening the command line form cxl-fixed-memory-window to cxl-fmw as the command lines are extremely long even with this change. The json change is needed to ensure that there is a CXLFixedMemoryWindowOptionsList even though the actual element in the json is never used. Similar to existing SgxEpcProperties. Update qemu-options.hx to reflect that this is now a -machine parameter. The bulk of -M / -machine parameters are documented under machine, so use that in preference to M. Update cxl-test and bios-tables-test to reflect new parameters.

2022-06-08target/arm: Implement FEAT_DoubleFaultPeter Maydell
The FEAT_DoubleFault extension adds the following: * All external aborts on instruction fetches and translation table walks for instruction fetches must be synchronous. For QEMU this is already true. * SCR_EL3 has a new bit NMEA which disables the masking of SError interrupts by PSTATE.A when the SError interrupt is taken to EL3. For QEMU we only need to make the bit writable, because we have no sources of SError interrupts. * SCR_EL3 has a new bit EASE which causes synchronous external aborts taken to EL3 to be taken at the same entry point as SError. (Note that this does not mean that they are SErrors for purposes of PSTATE.A masking or that the syndrome register reports them as SErrors: it just means that the vector offset is different.) * The existing SCTLR_EL3.IESB has an effective value of 1 when SCR_EL3.NMEA is 1. For QEMU this is a no-op because we don't need different behaviour based on IESB (we don't need to do anything to ensure that error exceptions are synchronized). So for QEMU the things we need to change are: * Make SCR_EL3.{NMEA,EASE} writable * When taking a synchronous external abort at EL3, adjust the vector entry point if SCR_EL3.EASE is set * Advertise the feature in the ID registers Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20220531151431.949322-1-peter.maydell@linaro.org
2022-06-08target/arm: Declare support for FEAT_RASv1p1Peter Maydell
The architectural feature RASv1p1 introduces the following new features: * new registers ERXPFGCDN_EL1, ERXPFGCTL_EL1 and ERXPFGF_EL1 * new bits in the fine-grained trap registers that control traps for these new registers * new trap bits HCR_EL2.FIEN and SCR_EL3.FIEN that control traps for ERXPFGCDN_EL1, ERXPFGCTL_EL1, ERXPFGP_EL1 * a larger number of the ERXMISC<n>_EL1 registers * the format of ERR<n>STATUS registers changes The architecture permits that if ERRIDR_EL1.NUM is 0 (as it is for QEMU) then all these new registers may UNDEF, and the HCR_EL2.FIEN and SCR_EL3.FIEN bits may be RES0. We don't have any ERR<n>STATUS registers (again, because ERRIDR_EL1.NUM is 0). QEMU does not yet implement the fine-grained-trap extension. So there is nothing we need to implement to be compliant with the feature spec. Make the 'max' CPU report the feature in its ID registers, and document it.

Revert that this is assigned automatically and immediately deprecate the compatibility parameter.

2022-06-01gitlab: don't run CI jobs in forks by defaultDaniel P. Berrangé
To preserve CI shared runner credits we don't want to run pipelines on every push. This sets up the config so that pipelines are never created for contributors by default. To override this the QEMU_CI variable can be set to a non-zero value. If set to 1, the pipeline will be created but all jobs will remain manually started. The contributor can selectively run jobs that they care about. If set to 2, the pipeline will be created and all jobs will immediately start. This behavior can be controlled using push variables git push -o ci.variable=QEMU_CI=1 To make this more convenient define an alias git config --local alias.push-ci "push -o ci.variable=QEMU_CI=1" git config --local alias.push-ci-now "push -o ci.variable=QEMU_CI=2" Which lets you run git push-ci to create the pipeline, or git push-ci-now to create and run the pipeline Signed-off-by: Daniel P.

2022-06-01gitlab: introduce a common base job templateDaniel P. Berrangé
Currently job rules are spread across the various templates and jobs, making it hard to understand exactly what runs in what scenario. This leads to inconsistency in the rules and increased maint burden. The intent is that we introduce a common '.base_job_template' which will have a general purpose 'rules:' block. No other template or job should define 'rules:', but instead they must rely on the inherited rules.

2022-05-19target/arm: Implement FEAT_IDSTPeter Maydell
The Armv8.4 feature FEAT_IDST specifies that exceptions generated by read accesses to the feature ID space should report a syndrome code of 0x18 (EC_SYSTEMREGISTERTRAP) rather than 0x00 (EC_UNCATEGORIZED). The feature ID space is defined to be: op0 == 3, op1 == {0,1,3}, CRn == 0, CRm == {0-7}, op2 == {0-7} In our implementation we might return the EC_UNCATEGORIZED syndrome value for a system register access in four cases: * no reginfo struct in the hashtable * cp_access_ok() fails (ie ri->access doesn't permit the access) * ri->accessfn returns CP_ACCESS_TRAP_UNCATEGORIZED at runtime * ri->type includes ARM_CP_RAISES_EXC, and the readfn raises an UNDEF exception at runtime We have very few regdefs that set ARM_CP_RAISES_EXC, and none of them are in the feature ID space. (In the unlikely event that any are added in future they would need to take care of setting the correct syndrome themselves.) This patch deals with the other three cases, and enables FEAT_IDST for AArch64 -cpu max.

2022-05-18docs/about: Update the support statement for WindowsThomas Huth
Our support statement for Windows currently talks about "Vista / Server 2008" - which is related to the API of Windows, and this is not easy to understand for the non-technical users. Additionally, glib sets the _WIN32_WINNT macro to 0x0601 already, which indicates the Windows 7 API, so QEMU effectively depends on the Windows 7 API, too. Thus let's bump the _WIN32_WINNT setting in QEMU to the same level as glib uses and adjust our support statement in the documentation to something similar that we're using for Linux and the *BSD systems (i.e. only the two most recent versions), which should hopefully be easier to understand for the users now. And since we're nowadays also compile-testing QEMU with MSYS2 on Windows itself, I think we could mention this build environment here, too.

2022-05-16docs/vhost-user: Clarifications for VHOST_USER_ADD/REM_MEM_REGKevin Wolf
The specification for VHOST_USER_ADD/REM_MEM_REG messages is unclear in several points, which has led to clients having incompatible implementations. This changes the specification to be more explicit about them: * VHOST_USER_ADD_MEM_REG is not specified as receiving a file descriptor, though it obviously does need to do so. All implementations agree on this one, fix the specification. * VHOST_USER_REM_MEM_REG is not specified as receiving a file descriptor either, and it also has no reason to do so. rust-vmm does not send file descriptors for removing a memory region (in agreement with the specification), libvhost-user and QEMU do (which is a bug), though libvhost-user doesn't actually make any use of it. Change the specification so that for compatibility QEMU's behaviour becomes legal, even if discouraged, but rust-vmm's behaviour becomes the explicitly recommended mode of operation. * VHOST_USER_ADD_MEM_REG doesn't have a documented return value, which is the desired behaviour in the non-postcopy case. It also implemented like this in QEMU and rust-vmm, though libvhost-user is buggy and sometimes sends an unexpected reply. This will be fixed in a separate patch. However, in postcopy mode it does reply like VHOST_USER_SET_MEM_TABLE. This behaviour is shared between libvhost-user and QEMU; rust-vmm doesn't implement postcopy mode yet. Mention it explicitly in the spec. * The specification doesn't mention how VHOST_USER_REM_MEM_REG identifies the memory region to be removed. Change it to describe the existing behaviour of libvhost-user (guest address, user address and size must match).

-audio is used like "-audio pa,model=sb16". It is almost as simple as -soundhw, but it reuses the -audiodev parsing machinery and attaches an audiodev to the newly-created device. The main 'feature' is that it knows about adding the codec device for model=intel-hda, and adding the audiodev to the codec device. In the future, it could be extended to support default models or builtin devices, just like -nic, or even a default backend. For now, keep it simple.
