* char: make some qemu_chr_fe skip if no driverMarc-André Lureau2016-10-241-10/+6Star
| | | | | | | | | | In most cases, front ends do not care about the side effect of CharBackend, so we can simply skip the checks and call the qemu_chr_fe functions even without associated CharDriver.

* char: use qemu_chr_fe* functions with CharBackend argumentMarc-André Lureau2016-10-241-8/+8
| | | | | | | | | | | This also switches from qemu_chr_add_handlers() to qemu_chr_fe_set_handlers(). Note that qemu_chr_fe_set_handlers() now takes the focus when fe_open (qemu_chr_add_handlers() did take the focus) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20161022095318.17775-16-marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* char: replace PROP_CHR with CharBackendMarc-André Lureau2016-10-241-7/+7
| | | | | | | | | | | Store the property in a CharBackend instead of CharDriverState*. This also replace systematically chr by chr.chr to access the CharDriverState*. The following patches will replace it with calls to qemu_chr_fe CharBackend functions.

* hw: replace most use of qemu_chr_fe_write with qemu_chr_fe_write_allDaniel P. Berrange2016-09-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah2016-03-221-1/+1
| | | | | | | | | | | | | | | | | | 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.

It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors.

* arm: memory: Replace memory_region_init_ram with ↵Dirk Müller2015-04-081-3/+4
| | | | | | | | | | | | | | | | | | | memory_region_allocate_system_memory Commit 0b183fc871:"memory: move mem_path handling to memory_region_allocate_system_memory" split memory_region_init_ram and memory_region_init_ram_from_file. Also it moved mem-path handling a step up from memory_region_init_ram to memory_region_allocate_system_memory. Therefore for any board that uses memory_region_init_ram directly, -mem-path is not supported. Fix this by replacing memory_region_init_ram with memory_region_allocate_system_memory.
