2017-06-02be-hci: use backend functionsMarc-André Lureau1-6/+3
Avoid accessing CharBackend directly, use qemu_chr_be_* methods instead. be->chr_read should exists if qemu_chr_be_can_write() is true. (use qemu_chr_be_write(), _impl() bypasses replay) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Andrzej Zaborowski <balrogg@gmail.com>

2017-06-02chardev: move headers to include/chardevMarc-André Lureau1-1/+1
So they are all in one place. The following patch will move serial & parallel declarations to the respective headers. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
2017-01-27chardev: qom-ifyMarc-André Lureau1-17/+38
Turn Chardev into Object. qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h. This is to help transition now (some types must be declared early, while some aren't shared) and when splitting in several units. This is to be improved later.

Use common allocator for CharDriverState. Rename the now untouched parent field. The casts added are temporary, they are replaced with QOM type-safe macros in a later patch in this series.

2017-01-27char: allocate CharDriverState as a single objectMarc-André Lureau1-5/+5
Use a single allocation for CharDriverState, this avoids extra allocations & pointers, and is a step towards more object-oriented CharDriver. Gtk console is a bit peculiar, gd_vc_chr_set_echo() used to have a temporary VirtualConsole to save the echo bit. Instead now, we consider whether vcd->console is set or not, and restore the echo bit saved in VCDriverState when calling gd_vc_vte_init(). The casts added are temporary, they are replaced with QOM type-safe macros in a later patch in this series.

2016-10-24char: replace avail_connectionsMarc-André Lureau1-1/+0
No need to count the users of a CharDriverState, it can rely on the fact of whether there is a CharBackend associated or if there is enough space in the muxer. Simplify and fold chr_mux_new_fe() in qemu_chr_fe_init() since there is a single user now. Also switch from fprintf to raising error instead.

2016-10-24char: move front end handlers in CharBackendMarc-André Lureau1-5/+7
Since the hanlders are associated with a CharBackend, rather than the CharDriverState, it is more appropriate to store in CharBackend. This avoids the handler copy dance in qemu_chr_fe_set_handlers() then mux_chr_update_read_handler(), by storing the CharBackend pointer directly. Also a mux CharDriver should go through mux->backends[focused], since chr->be will stay NULL. Before that, it was possible to call chr->handler by mistake with surprising results, for ex through qemu_chr_be_can_write(), which would result in calling the last set handler front end, not the one with focus.

2016-05-29bt: rewrite csrhci_write to avoid out-of-bounds writesPaolo Bonzini1-21/+46
The usage of INT_MAX in this function confuses Coverity. I think the defect is bogus, however there is no protection against getting more than sizeof(s->inpkt) bytes from the character device backend. Rewrite the function to only fill in as much data as needed from buf into s->inpkt. The plen variable is replaced by a simple state machine and there is no need anymore to shift contents to the beginning of s->inpkt. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19qemu-common: stop including qemu/bswap.h from qemu-common.hPaolo Bonzini1-0/+1

2016-03-22Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah1-2/+2
This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.
