2020-12-19migration: Replace migration's JSON writer by the general oneMarkus Armbruster1-1/+1
Commit 8118f0950f "migration: Append JSON description of migration stream" needs a JSON writer. The existing qobject_to_json() wasn't a good fit, because it requires building a QObject to convert. Instead, migration got its very own JSON writer, in commit 190c882ce2 "QJSON: Add JSON writer". It tacitly limits numbers to int64_t, and strings contents to characters that don't need escaping, unlike qobject_to_json(). The previous commit factored the JSON writer out of qobject_to_json(). Replace migration's JSON writer by it.

2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini1-0/+1
Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

2020-07-22goldfish_rtc: Fix non-atomic read behaviour of TIME_LOW/TIME_HIGHJessica Clarke1-3/+14
The specification says: 0x00 TIME_LOW R: Get current time, then return low-order 32-bits. 0x04 TIME_HIGH R: Return high 32-bits from previous TIME_LOW read. ... To read the value, the kernel must perform an IO_READ(TIME_LOW), which returns an unsigned 32-bit value, before an IO_READ(TIME_HIGH), which returns a signed 32-bit value, corresponding to the higher half of the full value. However, we were just returning the current time for both. If the guest is unlucky enough to read TIME_LOW and TIME_HIGH either side of an overflow of the lower half, it will see time be in the future, before jumping backwards on the next read, and Linux currently relies on the atomicity guaranteed by the spec so is affected by this. Fix this violation of the spec by caching the correct value for TIME_HIGH whenever TIME_LOW is read, and returning that value for any TIME_HIGH read.

2020-06-15qdev: Convert uses of qdev_create() with CoccinelleMarkus Armbruster2-4/+6
This is the transformation explained in the commit before previous. Takes care of just one pattern that needs conversion. More to come in this series. Coccinelle script: @ depends on !(file in "hw/arm/highbank.c")@ expression bus, type_name, dev, expr; @@ - dev = qdev_create(bus, type_name); + dev = qdev_new(type_name); ... when != dev = expr - qdev_init_nofail(dev); + qdev_realize_and_unref(dev, bus, &error_fatal); @@ expression bus, type_name, dev, expr; identifier DOWN; @@ - dev = DOWN(qdev_create(bus, type_name)); + dev = DOWN(qdev_new(type_name)); ... when != dev = expr - qdev_init_nofail(DEVICE(dev)); + qdev_realize_and_unref(DEVICE(dev), bus, &error_fatal); @@ expression bus, type_name, expr; identifier dev; @@ - DeviceState *dev = qdev_create(bus, type_name); + DeviceState *dev = qdev_new(type_name); ... when != dev = expr - qdev_init_nofail(dev); + qdev_realize_and_unref(dev, bus, &error_fatal); @@ expression bus, type_name, dev, expr, errp; symbol true; @@ - dev = qdev_create(bus, type_name); + dev = qdev_new(type_name); ... when != dev = expr - object_property_set_bool(OBJECT(dev), true, "realized", errp); + qdev_realize_and_unref(dev, bus, errp); @@ expression bus, type_name, expr, errp; identifier dev; symbol true; @@ - DeviceState *dev = qdev_create(bus, type_name); + DeviceState *dev = qdev_new(type_name); ... when != dev = expr - object_property_set_bool(OBJECT(dev), true, "realized", errp); + qdev_realize_and_unref(dev, bus, errp); The first rule exempts hw/arm/highbank.c, because it matches along two control flow paths there, with different @type_name.

2020-05-15qom: Drop parameter @errp of object_property_add() & friendsMarkus Armbruster1-2/+2
The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

Allwinner System-on-Chips usually contain a Real Time Clock (RTC) for non-volatile system date and time keeping. This commit adds a generic Allwinner RTC device that supports the RTC devices found in Allwinner SoC family sun4i (A10), sun7i (A20) and sun6i and newer (A31, H2+, H3, etc). The following RTC functionality and features are implemented: * Year-Month-Day read/write * Hour-Minute-Second read/write * General Purpose storage The following boards are extended with the RTC device: * Cubieboard (hw/arm/cubieboard.c) * Orange Pi PC (hw/arm/orangepi.c) Signed-off-by: Niek Linnenbank <nieklinnenbank@gmail.com> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Message-id: 20200311221854.30370-13-nieklinnenbank@gmail.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2019-11-19pl031: Expose RTCICR as proper WC registerAlexander Graf1-5/+1
The current PL031 RTCICR register implementation always clears the IRQ pending status on a register write, regardless of the value the guest writes. To justify that behavior, it references the ARM926EJ-S Development Chip Reference Manual (DDI0287B) and indicates that said document states that any write clears the internal IRQ state. It is indeed true that in section 11.1 this document says: "The interrupt is cleared by writing any data value to the interrupt clear register RTCICR". However, later in section 11.2.2 it contradicts itself by saying: "Writing 1 to bit 0 of RTCICR clears the RTCINTR flag." The latter statement matches the PL031 TRM (DDI0224C), which says: "Writing 1 to bit position 0 clears the corresponding interrupt. Writing 0 has no effect." Let's assume that the self-contradictory DDI0287B is in error, and follow the reference manual for the device itself, by making the register write-one-to-clear.

2019-11-19mc146818rtc: fix timer interrupt reinjection againPaolo Bonzini1-7/+9
Commit 369b41359af46bded5799c9ef8be2b641d92e043 broke timer interrupt reinjection when there is no period change by the guest. In that case, old_period is 0, which ends up zeroing irq_coalesced (counter of reinjected interrupts). The consequence is Windows 7 is unable to synchronize time via NTP. Easily reproducible by playing a fullscreen video with cirrus and VNC. Fix by passing s->period when periodic_timer_update is called due to expiration of the timer. With this change, old_period == 0 only means that the periodic timer was off.
