Richard Henderson	1b9177f749	semihosting: Create semihost_sys_poll_one This will be used for implementing the xtensa select_one system call. Choose "poll" over "select" so that we can reuse Glib's g_poll constants and to avoid struct timeval.

Philippe Mathieu-Daudé	6b5fe13786	semihosting: Move include/hw/semihosting/ -> include/semihosting/ We want to move the semihosting code out of hw/ in the next patch.

Keith Packard	8de702cb67	semihosting: add qemu_semihosting_console_inc for SYS_READC Provides a blocking call to read a character from the console using semihosting.chardev, if specified. This takes some careful command line options to use stdio successfully as the serial ports, monitor and semihost all want to use stdio. Here's a sample set of command line options which share stdio between semihost, monitor and serial ports: qemu \ -chardev stdio,mux=on,id=stdio0 \ -serial chardev:stdio0 \ -semihosting-config enable=on,chardev=stdio0 \ -mon chardev=stdio0,mode=readline This creates a chardev hooked to stdio and then connects all of the subsystems to it. A shorter mechanism would be good to hear about.

Markus Armbruster	ec150c7e09	include: Make headers more self-contained Back in 2016, we discussed[1] rules for headers, and these were generally liked: 1. Have a carefully curated header that's included everywhere first. We got that already thanks to Peter: osdep.h. 2. Headers should normally include everything they need beyond osdep.h. If exceptions are needed for some reason, they must be documented in the header. If all that's needed from a header is typedefs, put those into qemu/typedefs.h instead of including the header. 3. Cyclic inclusion is forbidden. This patch gets include/ closer to obeying 2. It's actually extracted from my "[RFC] Baby steps towards saner headers" series[2], which demonstrates a possible path towards checking 2 automatically. It passes the RFC test there.

Alex Bennée	78e24848f6	semihosting: split console_out into string and char versions This is ostensibly to avoid the weirdness of len looking like it might come from a guest and sometimes being used. While we are at it fix up the error checking for the arm-linux-user implementation of the API which got flagged up by Coverity (CID 1401700).

Markus Armbruster	37677d7db3	Clean up a few header guard symbols Commit `58ea30f514` "Clean up header guards that don't match their file name" messed up contrib/elf2dmp/qemu_elf.h and tests/migration/migration-test.h. It missed target/cris/opcode-cris.h and tests/uefi-test-tools/UefiTestToolsPkg/Include/Guid/BiosTablesTest.h due to the scripts/clean-header-guards.pl bug fixed in the previous commit. Commit `a8b991b52d` "Clean up ill-advised or unusual header guards" missed include/hw/xen/io/ring.h for the same reason. Commit `3979fca4b6` "disas: Rename include/disas/bfd.h back to include/disas/dis-asm.h" neglected to update the guard symbol for the rename. Commit `a331c6d774` "semihosting: implement a semihosting console" created include/hw/semihosting/console.h with an ill-advised guard symbol. Clean them up.
