2017-02-28ARM i.MX timers: fix reset handlingKurban Mallachiev
The i.MX timer device can be reset by writing to the SWR bit of the CR register. This has to behave differently from hard (power-on) reset because it does not reset all of the bits in the CR register. We were incorrectly implementing soft reset and hard reset the same way, and in addition had a logic error which meant that we were clearing the bits that soft-reset is supposed to preserve and not touching the bits that soft-reset clears. This was not correct behaviour for either kind of reset. Separate out the soft reset and hard reset code paths, and correct the handling of reset of the CR register so that it is correct in both cases.

2017-02-13migration: consolidate VMStateField.startHalil Pasic
The member VMStateField.start is used for two things, partial data migration for VBUFFER data (basically provide migration for a sub-buffer) and for locating next in QTAILQ. The implementation of the VBUFFER feature is broken when VMSTATE_ALLOC is used. This however goes unnoticed because actually partial migration for VBUFFER is not used at all. Let's consolidate the usage of VMStateField.start by removing support for partial migration for VBUFFER.

2017-02-06Split ISA and sysbus versions of m48t59 deviceDavid Gibson
The m48t59 device supports both ISA and direct sysbus attached versions of the device in the one .c file. This can be awkward for some embedded machine types which need the sysbus M48T59, but don't want to pull in the ISA bus code and its other dependencies. Therefore, this patch splits out the code for the ISA attached M48T59 into its own C file. It will be built when both CONFIG_M48T59 and CONFIG_ISA_BUS are enabled.

This patch disables the update of the periodic timer of mc146818rtc in record/replay mode. State of this timer is saved and therefore does not need to be updated in record/replay mode. Read of RTC breaks the replay because all rtc reads have to be the same as in record mode.

2016-10-04MC146818 RTC: coordinate guest clock base to destination host after migrationJunlian Bell
qemu tracks guest time based on vector [base_rtc, last_update], in which last_update stands for a monotonic tick which is actually uptime of the host. according to rtc implementation codes of recent releases and upstream, after migration, the time base vector [base_rtc, last_update] isn't updated to coordinate with the destionation host, ie. qemu doesnt update last_update to uptime of the destination host. what problem have we got because of this bug? after migration, guest time may jump back to several days ago, that will make some critical business applications, such as lotus notes, malfunction. this patch is trying to fix the problem. first, when vmsave in progress, we rtc_update_time to refresh time stamp in cmos array, then during vmrestore, we rtc_set_time to update qemu base_rtc and last_update variable according to time stamp in cmos array.

To ease implementation, all VPs are having its own QEMU timer but sharing global settings and registers such as GIC_SH_CONFIG.COUTNSTOP and GIC_SH_COUNTER.

2016-07-07i.MX: split the GPT timer implementation into per SOC definitionsJean-Christophe Dubois
In various Freescale SOCs, the GPT timers can be configured to select its input clock. Depending on the SOC the set of available input clocks may vary. The actual single GPT definition was no good enough and because of it booting the sabrelite board with a i.MX6DL device tree would fail because of an incorrect input clock definition for the i.MX6DL SOC. This patch fixes the i.MX6DL boot failure by adding the ability to define a different set of input clocks depending on the considered SOC. A different class has been defined for i.MX25, i.MX31 and i.MX6 each with its specific set of input clocks. The patch has been tested by booting KZM, i.MX25 PDK, i.MX6Q sabrelite and i.MX6DL sabrelite.

This change was originally intended to correct the HPET behavior in conjunction with Linux, however the behavior that it actually creates is not compatible with the ioapic.c implementation; it used to be compatible with KVM's own IOAPIC but it is not anymore.

2016-03-22Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah
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.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Implement basic ASPEED timer functionality for the AST2400 SoC[1]: Up to 8 timers can independently be configured, enabled, reset and disabled. Some hardware features are not implemented, namely clock value matching and pulse generation, but the implementation is enough to boot the Linux kernel configured with aspeed_defconfig.

2016-03-16i.MX: Add the CLK_IPG_HIGH clockJean-Christophe Dubois
EPIT, GPT and other i.MX timers are using "abstract" clocks among which a CLK_IPG_HIGH clock. On i.MX25 and i.MX31 CLK_IPG and CLK_IPG_HIGH are mapped to the same clock but on other SOC like i.MX6 they are mapped to distinct clocks. This patch add the CLK_IPG_HIGH to prepare for SOC where these 2 clocks are different.
