* chardev: Use QEMUChrEvent enum in IOEventHandler typedefPhilippe Mathieu-Daudé2020-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Chardev events are listed in the QEMUChrEvent enum. By using the enum in the IOEventHandler typedef we: - make the IOEventHandler type more explicit (this handler process out-of-band information, while the IOReadHandler is in-band), - help static code analyzers. This patch was produced with the following spatch script: @match@ expression backend, opaque, context, set_open; identifier fd_can_read, fd_read, fd_event, be_change; @@ qemu_chr_fe_set_handlers(backend, fd_can_read, fd_read, fd_event, be_change, opaque, context, set_open); @depends on match@ identifier opaque, event; identifier match.fd_event; @@ static -void fd_event(void *opaque, int event) +void fd_event(void *opaque, QEMUChrEvent event) { ... } Then the typedef was modified manually in include/chardev/char-fe.h.

| | | | | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

* hw: replace most use of qemu_chr_fe_write with qemu_chr_fe_write_allDaniel P. Berrange2016-09-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | The qemu_chr_fe_write method will return -1 on EAGAIN if the chardev backend write would block. Almost no callers of the qemu_chr_fe_write() method check the return value, instead blindly assuming data was successfully sent. In most cases this will lead to silent data loss on interactive consoles, but in some cases (eg RNG EGD) it'll just cause corruption of the protocol being spoken. We unfortunately can't fix the virtio-console code, due to a bug in the Linux guest drivers, which would cause the entire Linux kernel to hang if we delay processing of the incoming data in any way. Fixing this requires first fixing the guest driver to not hold spinlocks while writing to the hvc device backend. Fixes bug: https://bugs.launchpad.net/qemu/+bug/1586756 Signed-off-by: Daniel P.

* sysbus: Make devices picking up backends unavailable with -deviceMarkus Armbruster2015-04-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device models aren't supposed to go on fishing expeditions for backends. They should expose suitable properties for the user to set. For onboard devices, board code sets them. A number of sysbus devices pick up block backends in their init() / instance_init() methods with drive_get_next() instead: sl-nand, milkymist-memcard, pl181, generic-sdhci. Likewise, a number of sysbus devices pick up character backends in their init() / realize() methods with qemu_char_get_next_serial(): cadence_uart, digic-uart, etraxfs,serial, lm32-juart, lm32-uart, milkymist-uart, pl011, stm32f2xx-usart, xlnx.xps-uartlite. All these mistakes are already marked FIXME. See the commit that added these FIXMEs for a more detailed explanation of what's wrong. Fortunately, only machines ppce500 and pseries-* support -device with sysbus devices, and none of the devices above is supported with these machines. Set cannot_instantiate_with_device_add_yet to preserve our luck.

* hw: Mark devices picking up char backends actively FIXMEMarkus Armbruster2015-04-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Character devices defined with -serial and -parallel are for board initialization to wire up. Board code examines serial_hds[] and parallel_hds[] to find them, and creates devices with their qdev chardev properties set accordingly. Except a few devices go on a fishing expedition for a suitable backend instead of exposing a chardev property for board code to set: they use serial_hds[] (often via qemu_char_get_next_serial()) or parallel_hds[] in their realize() or init() method to connect to a backend. Picking up backends that way works when the devices are created by board code. But it's inappropriate for -device or device_add. Not only is it inconsistent with how the other characrer device models work (they connect to a backend explicitly identified by a "chardev" property), it breaks when the backend has been picked up by the board or a previous -device / device_add already. Example: $ qemu-system-ppc64 -M bamboo -S -device i82378 -device pc87312 -device pc87312 qemu-system-ppc64: -device pc87312: Property 'isa-parallel.chardev' can't take value 'parallel0', it's in use Mark them with suitable FIXME comments.
