2022-07-13scsi-disk: add SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk for ↵Mark Cave-Ayland
Macintosh Both MacOS and A/UX make use of vendor-specific MODE SELECT commands with PF=0 to identify SCSI devices: - MacOS sends a MODE SELECT command with PF=0 for the MODE_PAGE_VENDOR_SPECIFIC (0x0) mode page containing 2 bytes before initialising a disk - A/UX (installed on disk) sends a MODE SELECT command with PF=0 during SCSI bus enumeration, and gets stuck in an infinite loop if it fails Add a new SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk to allow both PF=0 MODE SELECT commands and implement a MODE_PAGE_VENDOR_SPECIFIC (0x0) mode page which is compatible with MacOS.

2022-07-13scsi-disk: add SCSI_DISK_QUIRK_MODE_SENSE_ROM_USE_DBD quirk for MacintoshMark Cave-Ayland
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.

2022-07-13scsi-disk: add MODE_PAGE_APPLE_VENDOR quirk for MacintoshMark Cave-Ayland
One of the mechanisms MacOS uses to identify CDROM drives compatible with MacOS is to send a custom MODE SELECT command for page 0x30 to the drive. The response to this is a hard-coded manufacturer string which must match in order for the CDROM to be usable within MacOS. Add an implementation of the MODE SELECT page 0x30 response guarded by a newly defined SCSI_DISK_QUIRK_MODE_PAGE_APPLE_VENDOR quirk bit so that CDROM drives attached to non-Apple machines function exactly as before.

2022-07-13cutils: Introduce bundle mechanismAkihiko Odaki
Developers often run QEMU without installing. The bundle mechanism allows to look up files which should be present in installation even in such a situation. It is a general mechanism and can find any files in the installation tree. The build tree will have a new directory, qemu-bundle, to represent what files the installation tree would have for reference by the executables. Note that it abandons compatibility with Windows older than 8. The extended support for the prior version, 7 ended more than 2 years ago, and it is unlikely that someone would like to run the latest QEMU on such an old system.

In 60592cfed2 ("hw/arm/virt: dt: add kaslr-seed property"), the kaslr-seed property was added, but the equally as important rng-seed property was forgotten about, which has identical semantics for a similar purpose. This commit implements it in exactly the same way as kaslr-seed. It then changes the name of the disabling option to reflect that this has more to do with randomness vs determinism, rather than something particular about kaslr.

2022-07-06ppc/pnv: assign pnv-phb-root-port chassis/slot earlierDaniel Henrique Barboza
It is not advisable to execute an object_dynamic_cast() to poke into bus->qbus.parent and follow it up with a C cast into the PnvPHB type we think we got. In fact this is not needed. There is nothing sophisticated being done with the PHB object retrieved during root_port_realize() for both PHB3 and PHB4. We're retrieving a PHB reference just to access phb->chip_id and phb->phb_id and use them to define the chassis/slot of the root port. phb->phb_id is already being passed to pnv_phb_attach_root_port() via the 'index' parameter. Let's also add a 'chip_id' parameter to this function and assign chassis and slot right there. This will spare us from the hassle of accessing the PHB object inside realize().

2022-06-30hw/misc/aspeed: Add PECI controllerPeter Delevoryas
This introduces a really basic PECI controller that responses to commands by always setting the response code to success and then raising an interrupt to indicate the command is done. This helps avoid getting hit with constant errors if the driver continuously attempts to send a command and keeps timing out. The AST2400 and AST2500 only included registers up to 0x5C, not 0xFC. They supported PECI 1.1, 2.0, and 3.0. The AST2600 and AST1030 support PECI 4.0, which includes more read/write buffer registers from 0x80 to 0xFC to support 64-byte mode. This patch doesn't attempt to handle that, or to create a different version of the controller for the different generations, since it's only implementing functionality that is common to all generations. The basic sequence of events is that the firmware will read and write to various registers and then trigger a command by setting the FIRE bit in the command register (similar to the I2C controller). Then the firmware waits for an interrupt from the PECI controller, expecting the interrupt status register to be filled in with info on what happened. If the command was transmitted and received successfully, then response codes from the host CPU will be found in the data buffer registers.

2022-06-30hw/i2c/aspeed: Add new-registers DMA slave mode RX supportPeter Delevoryas
This commit adds support for DMA RX in slave mode while using the new register set in the AST2600 and AST1030. This patch also pretty much assumes packet mode is enabled, I'm not sure if this will work in DMA step mode. This is particularly useful for testing IPMB exchanges between Zephyr and external devices, which requires multi-master I2C support and DMA in the new register mode, because the Zephyr drivers from Aspeed use DMA in the new mode by default. The Zephyr drivers are also using packet mode. The typical sequence of events for receiving data in DMA slave + packet mode is that the Zephyr firmware will configure the slave address register with an address to receive on and configure the bus's function control register to enable master mode and slave mode simultaneously at startup, before any transfers are initiated. RX DMA is enabled in the slave mode command register, and the slave RX DMA buffer address and slave RX DMA buffer length are set. TX DMA is not covered in this patch. When the Aspeed I2C controller receives data from some other I2C master, it will reset the I2CS_DMA_LEN RX_LEN value to zero, then buffer incoming data in the RX DMA buffer while incrementing the I2CC_DMA_ADDR address counter and decrementing the I2CC_DMA_LEN counter. It will also update the I2CS_DMA_LEN RX_LEN value along the way. Once all the data has been received, the bus controller will raise an interrupt indicating a packet command was completed, the slave address matched, a normal stop condition was seen, and the transfer was an RX operation. If the master sent a NACK instead of a normal stop condition, or the transfer timed out, then a slightly different set of interrupt status values would be set. Those conditions are not handled in this commit. The Zephyr firmware then collects data from the RX DMA buffer and clears the status register by writing the PKT_MODE_EN bit to the status register. In packet mode, clearing the packet mode interrupt enable bit also clears most of the other interrupt bits automatically (except for a few bits above it). Note: if the master transmit or receive functions were in use simultaneously with the slave mode receive functionality, then the master mode functions may have raised the interrupt line for the bus before the DMA slave transfer is complete. It's important to have the slave's interrupt status register clear throughout the receive operation, and if the slave attempts to raise the interrupt before the master interrupt status is cleared, then it needs to re-raise the interrupt once the master interrupt status is cleared. (And vice-versa). That's why in this commit, when the master interrupt status is cleared and the interrupt line is lowered, we call the slave interrupt _raise_ function, to see if the interrupt was pending. (And again, vice-versa). Signed-off-by: Peter Delevoryas <pdel@fb.com> Message-Id: <20220630045133.32251-8-me@pjd.dev> Signed-off-by: Cédric Le Goater <clg@kaod.org>

Add slave mode functionality for the Aspeed I2C controller in old register mode. This is implemented by realizing an I2C slave device owned by the I2C controller and attached to its own bus. The I2C slave device only implements asynchronous sends on the bus, so slaves not supporting that will not be able to communicate with it.

2022-06-30hw/i2c: add asynchronous sendKlaus Jensen
Add an asynchronous version of i2c_send() that requires the slave to explicitly acknowledge on the bus with i2c_ack(). The current master must use the new i2c_start_send_async() to indicate that it wants to do an asynchronous transfer. This allows the i2c core to check if the target slave supports this or not. This approach relies on adding a new enum i2c_event member, which is why a bunch of other devices needs changes in their event handling switches.
