2020-06-23qdev: Improve netdev property override error a bitMarkus Armbruster
qdev_prop_set_netdev() fails when the property already has a non-null value. Seems to go back to commit 30c367ed44 "qdev-properties-system.c: Allow vlan or netdev for -device, not both", v1.7.0. Board code doesn't expect failure, and crashes: $ qemu-system-x86_64 --nodefaults -nic user -netdev user,id=nic0 -global e1000.netdev=nic0 Unexpected error in error_set_from_qdev_prop_error() at /work/armbru/qemu/hw/core/qdev-properties.c:1101: qemu-system-x86_64: Property 'e1000.netdev' doesn't take value '__org.qemu.nic0 ' Aborted (core dumped) -device and device_add handle the failure: $ qemu-system-x86_64 -nodefaults -netdev user,id=net0 -netdev user,id=net1 -device e1000,netdev=net0,netdev=net1 qemu-system-x86_64: -device e1000,netdev=net0,netdev=net1: Property 'e1000.netdev' doesn't take value 'net1' $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -netdev user,id=net0 -netdev user,id=net1 -global e1000.netdev=net0 QEMU 5.0.50 monitor - type 'help' for more information (qemu) qemu-system-x86_64: warning: netdev net0 has no peer qemu-system-x86_64: warning: netdev net1 has no peer device_add e1000,netdev=net1 Error: Property 'e1000.netdev' doesn't take value 'net1' Perhaps netdev property override could be made to work.

2020-06-23qdev: Eliminate get_pointer(), set_pointer()Markus Armbruster
We stopped using get_pointer() and set_pointer() for netdev in commit 23120b13c6 "net: don't use set/get_pointer() in set/get_netdev()" (v2.3.0), and for chardev in commit becdfa00cf "char: replace PROP_CHR with CharBackend" (v2.8.0). With only the drive user left, they're not helpful anymore. Eliminate. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20200622094227.1271650-10-armbru@redhat.com>

2020-06-23fdc: Open-code fdctrl_init_isa()Markus Armbruster

2020-06-23fdc: Reject clash between -drive if=floppy and -global isa-fdcMarkus Armbruster
The floppy controller devices desugar their drive properties into floppy devices (since commit a92bd191a4 "fdc: Move qdev properties to FloppyDrive", v2.8.0). This involves some bad magic in fdctrl_connect_drives(), and exists for backward compatibility. The functions for boards to create floppy controller devices fdctrl_init_isa(), fdctrl_init_sysbus(), and sun4m_fdctrl_init() desugar -drive if=floppy to these floppy controller drive properties. If you use both -drive if=floppy (or its -fda / -fdb sugar) and -global isa-fdc for the same floppy device, -global silently loses the conflict, and both backends involved end up with the floppy device frontend attached, as demonstrated by iotest 172 (see commit before previous). This is wrong. Desugar -drive if=floppy straight to floppy devices instead, with helper fdctrl_init_drives(). The conflict now gets rejected cleanly: first, fdctrl_connect_drives() creates the floppy for the controller's property, then fdctrl_init_drives() attempts to create the floppy for -drive if=floppy, but fails because the unit is already in use. Output of iotest 172 changes in three ways: 1. The clash gets rejected. 2. In one test case, "info qtree" has the floppy devices swapped, and "info block" has their QOM paths swapped. This is because the floppy device for -fda now gets created after the one for -global isa-fdc.driveB. 3. The error message for -global floppy.drive=floppy0 changes. Before the patch, we set isa-fdc.driveA to -fda's block backend, then create the floppy device for it, then move the backend from isa-fdc.driveA to floppy.drive. Floppy creation fails when applying -global floppy.drive=floppy0, because floppy0 is still attached to isa-fdc. After the patch, we create the floppy for -fda, then set its drive property to floppy0. Now floppy creation succeeds, but setting the drive property fails, because -global already set it. Yes, this is exasperatingly complicated.

2020-06-19hw/riscv: sifive_u: Add a dummy DDR memory controller deviceBin Meng
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.

2020-06-19hw/riscv: sifive_u: Support different boot source per MSEL pin stateBin Meng
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.
