Experimental fork of QEMU with video encoding patches https://git.openslx.org/bwlp/qemu.git/atom/hw/i2c/trace-events?h=spice_video_codecs 2022-06-30T07:21:14+00:00 2022-06-30T07:21:14+00:00 Klaus Jensen 2022-06-30T07:21:14+00:00 urn:sha1:a78e9839ae5eb0b95d9db8dd672e2977d2831605 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.

This device is very common on BMCs to route a different channel to each PCIe i2c bus downstream from the BMC.

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.

Each Nuvoton SoC has 16 System Management Bus (SMBus). These buses compliant with SMBus and I2C protocol. This patch implements the single-byte mode of the SMBus. In this mode, the user sends or receives a byte each time. The SMBus device transmits it to the underlying i2c device and sends an interrupt back to the QEMU guest.
