hw/i386: move rtc-reset-reinjection command out of hw/rtc

2024-05-10T13:45:15Z

The rtc-reset-reinjection QMP command is specific to x86, other boards do not have the ACK tracking functionality that is needed for RTC interrupt reinjection. Therefore the QMP command is only included in x86, but qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c and requires tracking of all created RTC devices. Move the implementation to hw/i386, so that 1) it is available even if no RTC device exist 2) the only RTC that exists is easily found in x86ms->rtc.

hw/rtc/sun4v-rtc: Relicense to GPLv2-or-later

2024-03-07T12:54:56Z

The sun4v RTC device model added under commit a0e893039cf2ce0 in 2016 was unfortunately added with a license of GPL-v3-or-later, which is not compatible with other QEMU code which has a GPL-v2-only license. Relicense the code in the .c and the .h file to GPL-v2-or-later, to make it compatible with the rest of QEMU.

hw/rtc/aspeed_rtc: Use 64-bit offset for holding time_t difference

2023-08-31T08:45:18Z

In the aspeed_rtc device we store a difference between two time_t values in an 'int'. This is not really correct when time_t could be 64 bits. Enlarge the field to 'int64_t'. This is a migration compatibility break for the aspeed boards. While we are changing the vmstate, remove the accidental duplicate of the offset field.

hw/rtc: Rename rtc_[get|set]_memory -> mc146818rtc_[get|set]_cmos_data

2023-02-27T21:29:02Z

rtc_get_memory() and rtc_set_memory() helpers only work with TYPE_MC146818_RTC devices. 'memory' in their name refer to the CMOS region. Rename them as mc146818rtc_get_cmos_data() and mc146818rtc_set_cmos_data() to be explicit about what they are doing.

hw/rtc/mc146818rtc: Pass MC146818RtcState instead of ISADevice argument

rtc_get_memory() and rtc_set_memory() methods can not take any TYPE_ISA_DEVICE object. They expect a TYPE_MC146818_RTC one. Simplify the API by passing a MC146818RtcState. Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Richard Henderson Message-Id: <20230210233116.80311-3-philmd@linaro.org>

hw/rtc/mc146818rtc: Make the mc146818 RTC device target independent

2023-01-13T15:22:57Z

The only reason for this code being target dependent was the IRQ-counting related code in rtc_policy_slew_deliver_irq(). Since these functions have been moved into a new, separate file (kvm_irqcount.c) which is now always compiled and linked if necessary, we can get rid of the #ifdef TARGET_I386 switches in mc146818rtc.c and declare it in the softmmu_ss instead of specific_ss, so that the code only gets compiled once for all targets.

goldfish_rtc: Add big-endian property

2022-09-04T06:02:56Z

Add a new property "big-endian" to allow configuring the RTC as either little or big endian, the default is little endian. Currently overriding the default to big endian is only used by the m68k virt platform. New platforms should prefer to use little endian and not set this.
