2021-07-08hw/i2c: add support for PMBusTitus Rwantare
QEMU has support for SMBus devices, and PMBus is a more specific implementation of SMBus. The additions made in this commit makes it easier to add new PMBus devices to QEMU. https://pmbus.org/specification-archives/ Reviewed-by: Joel Stanley <joel@jms.id.au> Reviewed-by: Hao Wu <wuhaotsh@google.com> Signed-off-by: Titus Rwantare <titusr@google.com> Message-Id: <20210708172556.1868139-2-titusr@google.com> Signed-off-by: Corey Minyard <cminyard@mvista.com>
2021-07-08ipmi/sim: fix watchdog_expired data type error in IPMIBmcSim structJinhua Cao
1) watchdog_expired is set bool which value could only be 0 or 1, but watchdog_expired every bit mean different Timer Use. 2) Use the command -ipmitool mc get watchdog- to query ipmi-watchdog status in guest. ... [root@localhost ~]# ipmitool mc watchdog get Watchdog Timer Use: SMS/OS (0x44) Watchdog Timer Is: Started/Running Watchdog Timer Actions: Hard Reset (0x01) Pre-timeout interval: 0 seconds Timer Expiration Flags: 0x00 Initial Countdown: 60 sec Present Countdown: 57 sec ... bool for watchdog_expired results -Timer Expiration Flags- always be 0x00 or 0x01, but the -Timer Expiration Flags- indicts the Timer Use after timeout. So change watchdog_expired data type from bool to uint8_t to fix this problem.

2021-07-08hw/i2c: Introduce i2c_start_recv() and i2c_start_send()Philippe Mathieu-Daudé
To ease reviewing code using the I2C bus API, introduce the i2c_start_recv() and i2c_start_send() helpers which don't take the confusing 'is_recv' boolean argument. Use these new helpers in the SMBus / AUX bus models.

2021-06-15hw/intc/arm_gicv3_cpuif: Tolerate spurious EOIR writesJean-Philippe Brucker
Commit 382c7160d1cd ("hw/intc/arm_gicv3_cpuif: Fix EOIR write access check logic") added an assert_not_reached() if the guest writes the EOIR register while no interrupt is active. It turns out some software does this: EDK2, in GicV3ExitBootServicesEvent(), unconditionally write EOIR for all interrupts that it manages. This now causes QEMU to abort when running UEFI on a VM with GICv3. Although it is UNPREDICTABLE behavior and EDK2 does need fixing, the punishment seems a little harsh, especially since icc_eoir_write() already tolerates writes of nonexistent interrupt numbers. Display a guest error and tolerate spurious EOIR writes.

2021-06-15vga: Allow writing VBE_DISPI_ID5 to ID registerDennis Wölfing
The highest VBE_DISPI_INDEX_ID version supported by QEMU is VBE_DISPI_ID5. But currently QEMU only allows writing values up to VBE_DISPI_ID4 to the VBE_DISPI_INDEX_ID register. As a result of this when a lower version is written to this register and later VBE_DISPI_ID5 is written back, reads from the register will continue to report the lower version. Indeed SeaBIOS is doing that during VGA initialization which causes guests to always read VBE_DISPI_ID0 instead of the correct version.

2021-06-11vhost-vdpa: don't initialize backend_featuresJason Wang
We used to initialize backend_features during vhost_vdpa_init() regardless whether or not it was supported by vhost. This will lead the unsupported features like VIRTIO_F_IN_ORDER to be included and set to the vhost-vdpa during vhost_dev_start. Because the VIRTIO_F_IN_ORDER is not supported by vhost-vdpa so it won't be advertised to guest which will break the datapath. Fix this by not initializing the backend_features, so the acked_features could be built only from guest features via vhost_net_ack_features().

2021-06-11vhost-vdpa: map virtqueue notification area if possibleJason Wang
This patch implements the vq notification mapping support for vhost-vDPA. This is simply done by using mmap()/munmap() for the vhost-vDPA fd during device start/stop. For the device without notification mapping support, we fall back to eventfd based notification gracefully.

vDPA is not tie to any specific hardware, for safety and simplicity, vhost-vDPA doesn't allow MMIO area to be mapped via IOTLB. Only the doorbell could be mapped via mmap(). So this patch exclude skip the ram device from the IOTLB mapping. Reviewed-by: Si-Wei Liu <si-wei.liu@oracle.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

2021-06-08hw/riscv: microchip_pfsoc: Support direct kernel bootBin Meng
At present the Microchip Icicle Kit machine only supports using '-bios' to load the HSS, and does not support '-kernel' for direct kernel booting just like other RISC-V machines do. One has to use U-Boot which is chain-loaded by HSS, to load a kernel for testing. This is not so convenient. Adding '-kernel' support together with the existing '-bios', we follow the following table to select which payload we execute: -bios | -kernel | payload ------+------------+-------- N | N | HSS Y | don't care | HSS N | Y | kernel This ensures backwards compatibility with how we used to expose '-bios' to users. When '-kernel' is used for direct boot, '-dtb' must be present to provide a valid device tree for the board, as we don't generate device tree. When direct kernel boot is used, the OpenSBI fw_dynamic BIOS image is used to boot a payload like U-Boot or OS kernel directly. Documentation is updated to describe the direct kernel boot. Note as of today there is still no PolarFire SoC support in the upstream Linux kernel hence the document does not include instructions for that. It will be updated in the future.
