* watchdog/wdt_diag288: Mark diag288 watchdog as non-hotpluggableThomas Huth2017-08-301-0/+1

* shutdown: Add source information to SHUTDOWN and RESETEric Blake2017-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

* wdt: Add Aspeed watchdog device modelCédric Le Goater2017-02-072-0/+226
| | | | | | | | | | | | | | | | | | | | | | | | The Aspeed SoC includes a set of watchdog timers using 32-bit decrement counters, which can be based either on the APB clock or a 1 MHz clock. The watchdog timer is designed to prevent system deadlock and, in general, it should be restarted before timeout. When a timeout occurs, different types of signals can be generated, ARM reset, SOC reset, System reset, CPU Interrupt, external signal or boot from alternate block. The current model only performs the system reset function as this is used by U-Boot and Linux.

* Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah2016-03-222-2/+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.

* watchdog/diag288: avoid race condition on expired watchdogSascha Silbe2016-03-011-4/+8
| | | | | | | | | | | | | | | | | | When configured to inject an NMI, watchdog_perform_action() may cause the BQL to be temporarily relinquished (inject_nmi() → ... → s390_nmi() → s390_cpu_restart() → run_on_cpu()). When the guest issues diag 288 again in response to the NMI, the diag 288 operation will race against wdt_diag288_reset(). Depending on scheduler behaviour, wdt_diag288_reset() may be run after the guest issued a diag 288 Init. As a result, we will cancel the timer the guest just set up. The effect observed by the guest is that a second expiry does not trigger the watchdog action and diag 288 Change operations fail. Fix this by resetting the timer _before_ invoking the action.

* i6300esb: remove muldiv64()Laurent Vivier2015-09-251-8/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, timers were ticks based, and it made sense to add ticks to current time to know when to trigger an alarm. But since commit: 7447545 change all other clock references to use nanosecond resolution accessors All timers use nanoseconds and we need to convert ticks to nanoseconds, by doing something like: y = muldiv64(x, get_ticks_per_sec(), PCI_FREQUENCY) where x is the number of device ticks and y the number of system ticks. y is used as nanoseconds in timer functions, it works because 1 tick is 1 nanosecond. (get_ticks_per_sec() is 10^9) But as PCI frequency is 33 MHz, we can also do: y = x * 30; /* 33 MHz PCI period is 30 ns */ Which is much more simple. This implies a 33.333333 MHz PCI frequency, but this is correct. Signed-off-by: Laurent Vivier <lvivier@redhat.com>
* i6300esb: fix timer overflowLaurent Vivier2015-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | We use muldiv64() to compute the time to wait: timeout = muldiv64(get_ticks_per_sec(), timeout, 33000000); but get_ticks_per_sec() is 10^9 (30 bit value) and timeout is a 35 bit value. Whereas muldiv64 is: uint64_t muldiv64(uint64_t a, uint32_t b, uint32_t c) So we loose 3 bits of timeout. Swapping get_ticks_per_sec() and timeout fixes it. We can also replace it by a multiplication by 30 ns, but this changes PCI clock frequency from 33MHz to 33.333333MHz and we need to do this on all the QEMU PCI devices (later...)

* i6300esb: Fix signed integer overflowDavid Gibson2015-03-251-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the guest programs a sufficiently large timeout value an integer overflow can occur in i6300esb_restart_timer(). e.g. if the maximum possible timer preload value of 0xfffff is programmed then we end up with the calculation: timeout = get_ticks_per_sec() * (0xfffff << 15) / 33000000; get_ticks_per_sec() returns 1000000000 (10^9) giving: 10^9 * (0xfffff * 2^15) == 0x1dcd632329b000000 (65 bits) Obviously the division by 33MHz brings it back under 64-bits, but the overflow has already occurred. Since signed integer overflow has undefined behaviour in C, in theory this could be arbitrarily bad. In practice, the overflowed value wraps around to something negative, causing the watchdog to immediately expire, killing the guest, which is still fairly bad. The bug can be triggered by running a Linux guest, loading the i6300esb driver with parameter "heartbeat=2046" and opening /dev/watchdog. The watchdog will trigger as soon as the device is opened. This patch corrects the problem by using muldiv64(), which effectively allows a 128-bit intermediate value between the multiplication and division.
