Bin Meng 3eaea6eb4e hw/riscv: sifive_u: Add a dummy DDR memory controller device
It is enough to simply map the SiFive FU540 DDR memory controller
into the MMIO space using create_unimplemented_device(), to make
the upstream U-Boot v2020.07 DDR memory initialization codes happy.

Note we do not generate device tree fragment for the DDR memory
controller. Since the controller data in device tree consumes a
very large space (see fu540-hifive-unleashed-a00-ddr.dtsi in the
U-Boot source), and it is only needed by U-Boot SPL but not any
operating system, we choose not to generate the fragment here.
This also means when testing with U-Boot SPL, the device tree has
to come from U-Boot SPL itself, but not the one generated by QEMU
on the fly. The memory has to be set to 8GiB to match the real
HiFive Unleashed board when invoking QEMU (-m 8G).

With this commit, QEMU can boot U-Boot SPL built for SiFive FU540
all the way up to loading U-Boot proper from MMC:

$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -m 8G -bios u-boot-spl.bin

U-Boot SPL 2020.07-rc3-00208-g88bd5b1 (Jun 08 2020 - 20:16:10 +0800)
Trying to boot from MMC1
Unhandled exception: Load access fault
EPC: 0000000008009be6 TVAL: 0000000010050014

The above exception is expected because QSPI is unsupported yet.

Bin Meng 17aad9f276 hw/riscv: sifive_u: Support different boot source per MSEL pin state
SiFive FU540 SoC supports booting from several sources, which are
controlled using the Mode Select (MSEL[3:0]) pins on the chip.
Typically, the boot process runs through several stages before it
begins execution of user-provided programs.

The SoC supports booting from memory-mapped QSPI flash, which is
how start_in_flash property is used for at present. This matches
MSEL = 1 configuration (QSPI0).

Typical booting flows involve the Zeroth Stage Boot Loader (ZSBL).
It's not necessary for QEMU to implement the full ZSBL ROM codes,
because we know ZSBL downloads the next stage program into the L2
LIM at address 0x8000000 and executes from there. We can bypass
the whole ZSBL execution and use "-bios" to load the next stage
program directly if MSEL indicates a ZSBL booting flow.

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.

Yuri Benditovich e22f0603fb virtio-net: reference implementation of hash report
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.

We have a use case (vfio-ccw) where a CRW is already built and

reassemble it later, let's rework this code so we can queue a

Roman Kagan 4f44bbc5bb block: make BlockConf size props 32bit and accept size suffixes
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.

Roman Kagan 914e74cda9 qdev-properties: add size32 property type
Introduce size32 property type which handles size suffixes (k, m, g)
just like size property, but is uint32_t rather than uint64_t.  It's
going to be useful for properties that are byte sizes but are inherently
32bit, like BlkConf.opt_io_size or .discard_granularity (they are
switched to this new property type in a followup commit).

The getter for size32 is left out for a separate patch as its benefit is
less obvious, and it affects test output; for now the regular uint32
getter is used.

Roman Kagan c56ee92fcb block: consolidate blocksize properties consistency checks
Several block device properties related to blocksize configuration must
be in certain relationship WRT each other: physical block must be no
smaller than logical block; min_io_size, opt_io_size, and
discard_granularity must be a multiple of a logical block.

To ensure these requirements are met, add corresponding consistency
checks to blkconf_blocksizes, adjusting its signature to communicate
possible error to the caller.  Also remove the now redundant consistency
checks from the specific devices.

Sergio Lopez 49b44549ac virtio-blk: On restart, process queued requests in the proper context
On restart, we were scheduling a BH to process queued requests, which
would run before starting up the data plane, leading to those requests
being assigned and started on coroutines on the main context.

This could cause requests to be wrongly processed in parallel from
different threads (the main thread and the iothread managing the data
plane), potentially leading to multiple issues.

For example, stopping and resuming a VM multiple times while the guest
is generating I/O on a virtio_blk device can trigger a crash with a
stack tracing looking like this one:

Sergio Lopez 7aa1c247b4 virtio-blk: Refactor the code that processes queued requests
Move the code that processes queued requests from
virtio_blk_dma_restart_bh() to its own, non-static, function. This
will allow us to call it from the virtio_blk_data_plane_start() in a
future patch.

Robert Foley e51345eea9 include/qemu: Added tsan.h for annotations.
These annotations will allow us to give tsan
additional hints.  For example, we can inform
tsan about reads/writes to ignore to silence certain
classes of warnings.
We can also annotate threads so that the proper thread
naming shows up in tsan warning results.
