2016-01-29openrisc: Clean up includesPeter Maydell1-0/+1
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-30-git-send-email-peter.maydell@linaro.org
2015-09-25openrisc: remove muldiv64()Laurent Vivier1-4/+3
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(), TIMER_FREQ) 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 openrisc timer frequency is 20 MHz, we can also do: y = x * 50; /* 20 MHz period is 50 ns */ Signed-off-by: Laurent Vivier <lvivier@redhat.com>
2013-11-20openrisc-timer: Reduce overhead, Separate clock update functionsSebastian Macke1-10/+19
The clock value is only evaluated when really necessary reducing the overhead of the timer handling. This also solves a problem in the way the Linux kernel handles the timer and the expected accuracy. The old version could lead to inaccurate timings.

2013-08-22aio / timers: Switch entire codebase to the new timer APIAlex Bligh1-5/+5
This is an autogenerated patch using scripts/switch-timer-api. Switch the entire code base to using the new timer API. Note this patch may introduce some line length issues. Signed-off-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-08-22aio / timers: Rename qemu_timer_* functionsAlex Bligh1-1/+1
Rename four functions in preparation for new API. Rename qemu_timer_expired to timer_expired Rename qemu_timer_expire_time_ns to timer_expire_time_ns Rename qemu_timer_pending to timer_pending Rename qemu_timer_expired_ns to timer_expired_ns Signed-off-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-03-12cpu: Move halted and interrupt_request fields to CPUStateAndreas Färber1-1/+3
Both fields are used in VMState, thus need to be moved together. Explicitly zero them on reset since they were located before breakpoints. Pass PowerPCCPU to kvmppc_handle_halt(). Signed-off-by: Andreas Färber <afaerber@suse.de>
