2020-06-19hw/intc: Initial commit of lowRISC Ibex PLICAlistair Francis
The Ibex core contains a PLIC that although similar to the RISC-V spec is not RISC-V spec compliant. This patch implements a Ibex PLIC in a somewhat generic way. As the current RISC-V PLIC needs tidying up, my hope is that as the Ibex PLIC move towards spec compliance this PLIC implementation can be updated until it can replace the current PLIC.

2020-06-19tpm: Move backend code under the 'backends/' directoryPhilippe Mathieu-Daudé
TPM subsytem is split into backends (see commit f4ede81eed2) and frontends (see i.e. 3676bc69b35). Keep the emulated hardware 'frontends' under hw/tpm/, but move the backends in the backends/tpm/ directory.

The trace_event_get_state_backends() call is useful to avoid making extensive calls (usually preparing arguments passed to the tracing framework. In this case, the extensive work is done in tpm_util_show_buffer(), and the arguments used to call it don't involve extra processing.

2020-06-18Fix tulip breakageHelge Deller
The tulip network driver in a qemu-system-hppa emulation is broken in the sense that bigger network packages aren't received any longer and thus even running e.g. "apt update" inside the VM fails. The breakage was introduced by commit 8ffb7265af ("check frame size and r/w data length") which added checks to prevent accesses outside of the rx/tx buffers. But the new checks were implemented wrong. The variable rx_frame_len counts backwards, from rx_frame_size down to zero, and the variable len is never bigger than rx_frame_len, so accesses just can't happen and the checks are unnecessary. On the contrary the checks now prevented bigger packages to be moved into the rx buffers. This patch reverts the wrong checks and were sucessfully tested with a qemu-system-hppa emulation.

Suggest VIRTIO_NET_F_HASH_REPORT if specified in device parameters. If the VIRTIO_NET_F_HASH_REPORT is set, the device extends configuration space. If the feature is negotiated, the packet layout is extended to accomodate the hash information. In this case deliver packet's hash value and report type in virtio header extension. Use for configuration the same procedure as already used for RSS. We add two fields in rss_data that controls what the device does with the calculated hash if rss_data.enabled is set. If field 'populate' is set the hash is set in the packet, if field 'redirect' is set the hash is used to decide the queue to place the packet to.

2020-06-18vfio-ccw: Add support for the CRW region and IRQFarhan Ali
The crw region can be used to obtain information about Channel Report Words (CRW) from vfio-ccw driver. Currently only channel-path related CRWs are passed to QEMU from vfio-ccw driver.

2020-06-18s390x/css: Refactor the css_queue_crw() routineEric Farman
We have a use case (vfio-ccw) where a CRW is already built and ready to use. Rather than teasing out the components just to reassemble it later, let's rework this code so we can queue a fully-qualified CRW directly.

2020-06-18vfio-ccw: Add support for the schib regionFarhan Ali
The schib region can be used to obtain the latest SCHIB from the host passthrough subchannel. Since the guest SCHIB is virtualized, we currently only update the path related information so that the guest is aware of any path related changes when it issues the 'stsch' instruction.

While we're at it, add a g_free() for the async_cmd_region that is the last thing currently created. g_free() knows how to handle NULL pointers, so this makes it easier to remember what cleanups need to be performed when new regions are added.

2020-06-17block: lift blocksize property limit to 2 MiBRoman Kagan
Logical and physical block sizes in QEMU are limited to 32 KiB. This appears unnecessarily tight, and we've seen bigger block sizes handy at times. Lift the limitation up to 2 MiB which appears to be good enough for everybody, and matches the qcow2 cluster size limit.

2020-06-17qdev-properties: add getter for size32 and blocksizeRoman Kagan
Add getter for size32, and use it for blocksize, too. In its human-readable branch, it reports approximate size in human-readable units next to the exact byte value, like the getter for 64bit size does. Adjust the expected test output accordingly.

2020-06-17block: make BlockConf size props 32bit and accept size suffixesRoman Kagan
Convert all size-related properties in BlockConf to 32bit. This will accommodate bigger block sizes (in a followup patch). This also allows to make them all accept size suffixes, either via DEFINE_PROP_BLOCKSIZE or via DEFINE_PROP_SIZE32. Also, since min_io_size is exposed to the guest by scsi and virtio-blk devices as an uint16_t in units of logical blocks, introduce an additional check in blkconf_blocksizes to prevent its silent truncation.

2020-06-17qdev-properties: make blocksize accept size suffixesRoman Kagan
It appears convenient to be able to specify physical_block_size and logical_block_size using common size suffixes. Teach the blocksize property setter to interpret them. Also express the upper and lower limits in the respective units.
