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.

2020-06-23iotests/172: Cover -global floppy.drive=...Markus Armbruster
Use of -global to set a default backend for non-singleton devices is a bad idea. But as long as we permit it, we better test it. Test output demonstrates we screw up when -global floppy clashes with -fda or with -device floppy: according to "info qtree", only the latter backend is attached, but according to "info block", both are. Here's the clash with -device: Testing: -drive if=none,file=TEST_DIR/t.qcow2 -drive if=none,file=TEST_DIR/t.qcow2.2 -global floppy.drive=none0 -device floppy,drive=none1,unit=0 dev: isa-fdc, id "" [...] driveA = "" driveB = "" [...] bus: floppy-bus.0 type floppy-bus dev: floppy, id "" unit = 0 (0x0) ---> drive = "none1" [...] none0 (NODE_NAME): TEST_DIR/t.qcow2 (qcow2) ---> Attached to: /machine/peripheral-anon/device[0] Cache mode: writeback none1 (NODE_NAME): TEST_DIR/t.qcow2.2 (qcow2) ---> Attached to: /machine/peripheral-anon/device[0] Removable device: not locked, tray closed Cache mode: writeback /machine/peripheral-anon/device[0] is the floppy created with -device. Test output further demonstrates the "Drive 'FOO' is already in use because it has been automatically connected to another device" error message can be misleading. With '-fda "" -global floppy.drive=floppy0', it's in use because -global reuses -fda's backend. There is no other device involved.

2020-06-23iotests/172: Include "info block" in test outputMarkus Armbruster
The additional output demonstrates we screw up when -global isa-fdc clashes with -drive if=floppy or its sugared forms: according to "info qtree", only the latter backend is attached, but according to "info block", both are. For instance: Testing: -fda TEST_DIR/t.qcow2 -drive if=none,file=TEST_DIR/t.qcow2.2 -global isa-fdc.driveA=none0 dev: isa-fdc, id "" [...] driveA = "" driveB = "" [...] bus: floppy-bus.0 type floppy-bus dev: floppy, id "" unit = 0 (0x0) ---> drive = "floppy0" [...] floppy0 (NODE_NAME): TEST_DIR/t.qcow2 (qcow2) ---> Attached to: /machine/unattached/device[15] Removable device: not locked, tray closed Cache mode: writeback none0 (NODE_NAME): TEST_DIR/t.qcow2.2 (qcow2) ---> Attached to: /machine/unattached/device[14] Cache mode: writeback /machine/unattached/device[15] is floppy, and /machine/unattached/device[14] is isa-fdc.

2020-06-23target/arm: Remove unnecessary gen_io_end() callsPeter Maydell
Since commit ba3e7926691ed3 it has been unnecessary for target code to call gen_io_end() after an IO instruction in icount mode; it is sufficient to call gen_io_start() before it and to force the end of the TB. Many now-unnecessary calls to gen_io_end() were removed in commit 9e9b10c6491153b, but some were missed or accidentally added later. Remove unneeded calls from the arm target: * the call in the handling of exception-return-via-LDM is unnecessary, and the code is already forcing end-of-TB * the call in the VFP access check code is more complicated: we weren't ending the TB, so we need to add the code to force that by setting DISAS_UPDATE * the doc comment for ARM_CP_IO doesn't need to mention gen_io_end() any more Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru> Message-id: 20200619170324.12093-1-peter.maydell@linaro.org
2020-06-23target/arm: Move some functions used only in translate-neon.inc.c to that filePeter Maydell
The functions neon_element_offset(), neon_load_element(), neon_load_element64(), neon_store_element() and neon_store_element64() are used only in the translate-neon.inc.c file, so move their definitions there. Since the .inc.c file is #included in translate.c this doesn't make much difference currently, but it's a more logical place to put the functions and it might be helpful if we ever decide to try to make the .inc.c files genuinely separate compilation units.

Convert the Neon VTRN insn to decodetree. This is the last insn in the Neon data-processing group, so we can remove all the now-unused old decoder framework. It's possible that there's a more efficient implementation of VTRN, but for this conversion we just copy the existing approach.

Convert the Neon VSWP insn to decodetree.
