2021-03-04ui/console: Add placeholder flag to message surfaceAkihiko Odaki
The surfaces created with former qemu_create_message_surface did not display the content from the guest and always contained simple messages describing the reason. A display backend may want to hide the window showing such a surface. This change renames the function to qemu_create_placeholder_surface, and adds "placeholder" flag; the display can check the flag to decide to do anything special like hiding the window.

2021-03-04configure: Improve OpenGL dependency detectionsAkihiko Odaki
This has the following visible changes: - GBM is required only for OpenGL dma-buf. - X11 is explicitly required by gtk-egl. - EGL is now mandatory for the OpenGL displays. The last one needs some detailed description. Before this change, EGL was tested only for OpenGL dma-buf with the check of EGL_MESA_image_dma_buf_export. However, all of the OpenGL displays depend on EGL and EGL_MESA_image_dma_buf_export is always defined by epoxy's EGL interface. Therefore, it makes more sense to always check the presence of EGL and say the OpenGL displays are available along with OpenGL dma-buf if it is present.

2021-02-23acpi/core: always set SCI_EN when SMM isn't supportedIsaku Yamahata
If SMM is not supported, ACPI fixed hardware doesn't support legacy-mode. ACPI-only platform. Where SCI_EN in PM1_CNT register is always set. The bit tells OS legacy mode(SCI_EN cleared) or ACPI mode(SCI_EN set). With the next patch (setting fadt.smi_cmd = 0 when smm isn't enabled), guest Linux tries to switch to ACPI mode, finds smi_cmd = 0, and then fails to initialize acpi subsystem. This patch proactively fixes it. This patch changes guest ABI. To keep compatibility, use "smm-compat" introduced by earlier patch. If the property is true, disable new behavior.

2021-02-18accel/tcg: allow plugin instrumentation to be disable via cflagsAlex Bennée
When icount is enabled and we recompile an MMIO access we end up double counting the instruction execution. To avoid this we introduce the CF_MEMI cflag which only allows memory instrumentation for the next TB (which won't yet have been counted). As this is part of the hashed compile flags we will only execute the generated TB while coming out of a cpu_io_recompile. While we are at it delete the old TODO. We might as well keep the translation handy as it's likely you will repeatedly hit it on each MMIO access.

2021-02-16replay: fix icount request when replaying clock accessPavel Dovgalyuk
Record/replay provides REPLAY_CLOCK_LOCKED macro to access the clock when vm_clock_seqlock is locked. This macro is needed because replay internals operate icount. In locked case replay use icount_get_raw_locked for icount request, which prevents excess locking which leads to deadlock. But previously only record code used *_locked function and replay did not. Therefore sometimes clock access lead to deadlocks. This patch fixes clock access for replay too and uses *_locked icount access function.

2021-02-16sev/i386: Don't allow a system reset under an SEV-ES guestTom Lendacky
An SEV-ES guest does not allow register state to be altered once it has been measured. When an SEV-ES guest issues a reboot command, Qemu will reset the vCPU state and resume the guest. This will cause failures under SEV-ES. Prevent that from occuring by introducing an arch-specific callback that returns a boolean indicating whether vCPUs are resettable.

2021-02-16sev/i386: Allow AP booting under SEV-ESPaolo Bonzini
When SEV-ES is enabled, it is not possible modify the guests register state after it has been initially created, encrypted and measured. Normally, an INIT-SIPI-SIPI request is used to boot the AP. However, the hypervisor cannot emulate this because it cannot update the AP register state. For the very first boot by an AP, the reset vector CS segment value and the EIP value must be programmed before the register has been encrypted and measured. Search the guest firmware for the guest for a specific GUID that tells Qemu the value of the reset vector to use. Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: "Michael S.

2021-02-16pc: add parser for OVMF reset blockJames Bottomley
OVMF is developing a mechanism for depositing a GUIDed table just below the known location of the reset vector. The table goes backwards in memory so all entries are of the form <data>|len|<GUID> Where <data> is arbtrary size and type, <len> is a uint16_t and describes the entire length of the entry from the beginning of the data to the end of the guid. The foot of the table is of this form and <len> for this case describes the entire size of the table. The table foot GUID is defined by OVMF as 96b582de-1fb2-45f7-baea-a366c55a082d and if the table is present this GUID is just below the reset vector, 48 bytes before the end of the firmware file. Add a parser for the ovmf reset block which takes a copy of the block, if the table foot guid is found, minus the footer and a function for later traversal to return the data area of any specified GUIDs.

2021-02-16hw/i2c: Implement NPCM7XX SMBus Module FIFO ModeHao Wu
This patch implements the FIFO mode of the SMBus module. In FIFO, the user transmits or receives at most 16 bytes at a time. The FIFO mode allows the module to transmit large amount of data faster than single byte mode. Since we only added the device in a patch that is only a few commits away in the same patch set. We do not increase the VMstate version number in this special case.

Use g2h_untagged in contexts that have no cpu, e.g. the binary loaders that operate before the primary cpu is created. As a colollary, target_mmap and friends must use untagged addresses, since they are used by the loaders. Use g2h_untagged on values returned from target_mmap, as the kernel never applies a tag itself. Use g2h_untagged on all pc values. The only current user of tags, aarch64, removes tags from code addresses upon branch, so "pc" is always untagged. Use g2h with the cpu context on hand wherever possible. Use g2h_untagged in lock_user, which will be updated soon.

Record whether the backing page is anonymous, or if it has file backing. This will allow us to get close to the Linux AArch64 ABI for MTE, which allows tag memory only on ram-backed VMAs. The real ABI allows tag memory on files, when those files are on ram-backed filesystems, such as tmpfs. We will not be able to implement that in QEMU linux-user. Thankfully, anonymous memory for malloc arenas is the primary consumer of this feature, so this restricted version should still be of use.
