2022-07-18lasips2: remove the qdev base property and the lasips2_properties arrayMark Cave-Ayland2-10/+2
The base property was only needed for use by vmstate_register() in order to preserve migration compatibility. Now that the lasips2 migration state is registered through the DeviceClass vmsd field, the base property and also the lasips2_properties array can be removed completely as they are no longer required.

2022-07-18lasips2: don't use vmstate_register() in lasips2_realize()Mark Cave-Ayland1-2/+1
Since lasips2 is a qdev device then vmstate_ps2_mouse can be registered using the DeviceClass vmsd field instead. Note that due to the use of the base parameter in the original vmstate_register() function call, this is actually a migration break for the HPPA B160L machine.

2022-07-18hw/intc/armv7m_nvic: ICPRn must not unpend an IRQ that is being held highPeter Maydell1-1/+8
In the M-profile Arm ARM, rule R_CVJS defines when an interrupt should be set to the Pending state: A) when the input line is high and the interrupt is not Active B) when the input line transitions from low to high and the interrupt is Active (Note that the first of these is an ongoing condition, and the second is a point-in-time event.) This can be rephrased as: 1 when the line goes from low to high, set Pending 2 when Active goes from 1 to 0, if line is high then set Pending 3 ignore attempts to clear Pending when the line is high and Active is 0 where 1 covers both B and one of the "transition into condition A" cases, 2 deals with the other "transition into condition A" possibility, and 3 is "don't drop Pending if we're already in condition A". Transitions out of condition A don't affect Pending state. We handle case 1 in set_irq_level(). For an interrupt (as opposed to other kinds of exception) the only place where we clear Active is in armv7m_nvic_complete_irq(), where we handle case 2 by checking for whether we need to re-pend the exception. For case 3, the only places where we clear Pending state on an interrupt are in armv7m_nvic_acknowledge_irq() (where we are setting Active so it doesn't count) and for writes to NVIC_ICPRn. It is the "write to NVIC_ICPRn" case that we missed: we must ignore this if the input line is high and the interrupt is not Active. (This required behaviour is differently and perhaps more clearly stated in the v7M Arm ARM, which has pseudocode in section B3.4.1 that implies it.)

2022-07-15hw/nvme: Use ioeventfd to handle doorbell updatesJinhao Fan2-1/+117
Add property "ioeventfd" which is enabled by default. When this is enabled, updates on the doorbell registers will cause KVM to signal an event to the QEMU main loop to handle the doorbell updates. Therefore, instead of letting the vcpu thread run both guest VM and IO emulation, we now use the main loop thread to do IO emulation and thus the vcpu thread has more cycles for the guest VM. Since ioeventfd does not tell us the exact value that is written, it is only useful when shadow doorbell buffer is enabled, where we check for the value in the shadow doorbell buffer when we get the doorbell update event.

Since commit 916b0f0b5264 ("hw/nvme: change nvme-ns 'shared' default") the default value of nvme-ns param 'shared' is set to true, regardless if there is a nvme-subsys node or not. On a system without a nvme-subsys node, a namespace will never be able to be attached to more than one controller, so for this configuration, it is counterintuitive for this parameter to be set by default. Force the nvme-ns param 'shared' to false for configurations where there is no nvme-subsys node, as the namespace will never be able to attach to more than one controller anyway.

2022-07-15hw/nvme: Implement shadow doorbell buffer supportJinhao Fan2-1/+122
Implement Doorbel Buffer Config command (Section 5.7 in NVMe Spec 1.3) and Shadow Doorbel buffer & EventIdx buffer handling logic (Section 7.13 in NVMe Spec 1.3). For queues created before the Doorbell Buffer Config command, the nvme_dbbuf_config function tries to associate each existing SQ and CQ with its Shadow Doorbel buffer and EventIdx buffer address. Queues created after the Doorbell Buffer Config command will have the doorbell buffers associated with them when they are initialized. In nvme_process_sq and nvme_post_cqe, proactively check for Shadow Doorbell buffer changes instead of wait for doorbell register changes. This reduces the number of MMIOs. In nvme_process_db(), update the shadow doorbell buffer value with the doorbell register value if it is the admin queue. This is a hack since hosts like Linux NVMe driver and SPDK do not use shadow doorbell buffer for the admin queue. Copying the doorbell register value to the shadow doorbell buffer allows us to support these hosts as well as spec-compliant hosts that use shadow doorbell buffer for the admin queue.

There are currently performance issues with this method (TBs being flushed too often), so as a faster alternative, install the flash contents as a ROM in the BMC memory space.

2022-07-14aspeed: Refactor UART init for multi-SoC machinesPeter Delevoryas4-22/+66
This change moves the code that connects the SoC UART's to serial_hd's to the machine. It makes each UART a proper child member of the SoC, and then allows the machine to selectively initialize the chardev for each UART with a serial_hd. This should preserve backwards compatibility, but also allow multi-SoC boards to completely change the wiring of serial devices from the command line to specific SoC UART's. This also removes the uart-default property from the SoC, since the SoC doesn't need to know what UART is the "default" on the machine anymore. I tested this using the images and commands from the previous refactoring, and another test image for the ast1030: wget https://github.com/facebook/openbmc/releases/download/v2021.49.0/fuji.mtd wget https://github.com/facebook/openbmc/releases/download/v2021.49.0/wedge100.mtd wget https://github.com/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf Fuji uses UART1: qemu-system-arm -machine fuji-bmc \ -drive file=fuji.mtd,format=raw,if=mtd \ -nographic ast2600-evb uses uart-default=UART5: qemu-system-arm -machine ast2600-evb \ -drive file=fuji.mtd,format=raw,if=mtd \ -serial null -serial mon:stdio -display none Wedge100 uses UART3: qemu-system-arm -machine palmetto-bmc \ -drive file=wedge100.mtd,format=raw,if=mtd \ -serial null -serial null -serial null \ -serial mon:stdio -display none AST1030 EVB uses UART5: qemu-system-arm -machine ast1030-evb \ -kernel Y35BCL.elf -nographic Fixes: 6827ff20b2975 ("hw: aspeed: Init all UART's with serial devices") Signed-off-by: Peter Delevoryas <peter@pjd.dev> Reviewed-by: Cédric Le Goater <clg@kaod.org> Message-Id: <20220705191400.41632-4-peter@pjd.dev> Signed-off-by: Cédric Le Goater <clg@kaod.org>
2022-07-14aspeed: Create SRAM name from first CPU indexPeter Delevoryas3-5/+10
To support multiple SoC's running simultaneously, we need a unique name for each RAM region. DRAM is created by the machine, but SRAM is created by the SoC, since in hardware it is part of the SoC's internals. We need a way to uniquely identify each SRAM region though, for VM migration. Since each of the SoC's CPU's has an index which identifies it uniquely from other CPU's in the machine, we can use the index of any of the CPU's in the SoC to uniquely identify differentiate the SRAM name from other SoC SRAM's. In this change, I just elected to use the index of the first CPU in each SoC.

2022-07-13scsi-disk: add SCSI_DISK_QUIRK_MODE_PAGE_TRUNCATED quirk for MacintoshMark Cave-Ayland2-1/+7
When A/UX configures the CDROM device it sends a truncated MODE SELECT request for page 1 (MODE_PAGE_R_W_ERROR) which is only 6 bytes in length rather than 10. This seems to be due to bug in Apple's code which calculates the CDB message length incorrectly. The work at [1] suggests that this truncated request is accepted on real hardware whereas in QEMU it generates an INVALID_PARAM_LEN sense code which causes A/UX to get stuck in a loop retrying the command in an attempt to succeed. Alter the mode page request length check so that truncated requests are allowed if the SCSI_DISK_QUIRK_MODE_PAGE_TRUNCATED quirk is enabled, whilst also adding a trace event to enable the condition to be detected.

2022-07-13scsi-disk: add SCSI_DISK_QUIRK_MODE_SENSE_ROM_USE_DBD quirk for MacintoshMark Cave-Ayland1-4/+23
During SCSI bus enumeration A/UX sends a MODE SENSE command to the CDROM with the DBD bit unset and expects the response to include a block descriptor. As per the latest SCSI documentation, QEMU currently force-disables the block descriptor for CDROM devices but the A/UX driver expects the requested block descriptor to be returned. If the block descriptor is not returned in the response then A/UX becomes confused, since the block descriptor returned in the MODE SENSE response is used to generate a subsequent MODE SELECT command which is then invalid. Add a new SCSI_DISK_QUIRK_MODE_SENSE_ROM_USE_DBD quirk to allow this behaviour to be enabled as required. Note that an additional workaround is required for the previous SCSI_DISK_QUIRK_MODE_PAGE_APPLE_VENDOR quirk which must never return a block descriptor even though the DBD bit is left unset.
