This patch series adds support for the Epson RX8900 RTC to the
Aspeed board.
The tests use the existing imx25 infrastructure, and some minor
changes have been made to uniquely identify the I2C buses.
Support for named interrupts has been implemented in qtest to
facilitate testing.
Changelog:
v5:
- Use time functions for time manipulation (note: check-patch
incorrectly reports an error on timercmp())
- Refactor weekday validation
- Defer time offset calculation until the I2C transaction is
complete as partial updates can result in incorrect offsets
- Cosmetic changes as requested by Adrew Jeffery
v4:
- Split overloaded patches
- Fix spelling of Celsius
- Remove degrees sign from messages
- Don't force float precision
- Reformat named interrupt qtest protocol for consistency
- Minor formatting changes
- Don't connect the RX8900 INT line to NVIC:22, it should be
connected to GPIOJ10 on the ASPEED SOC
v3:
- Add range checks for time components
- Shorten trace messages
- Use qemu generated i2c bus names
- Address style comments from Alexey for rx8900 driver
- Fix long lines in qtest harness
- Remove trailing whitespace in hw/arm/pxa
- Remove stray headers from rx8900 driver
- Support low voltage detection in rx8900 driver
v2:
- Avoid using error_report
- Fix TIE behaviour
- Move temperature init out of reset, it should not change
on a soft reset
- Fix IRQ in test failures
- Add a NULL check for i2c slave init callbacks, so that we
no longer need to implement empty init functions.
- Refactor to use the existing qemu trace infrastructure
- Move the RX8900 definition into the aspeed machine init
- It it possible for check_update_interrupt_seconds in the
rx8900 test to return 6, depending on the alignment with
the wall clock.
- Support low voltage detection
Alastair D'Silva (7):
arm: Uniquely name imx25 I2C buses.
qtest: Support named interrupts
qtest: Support setting named GPIOs
qtest: Fix whitespace
hw/timer: Add Epson RX8900 RTC support
tests: Test all implemented RX8900 functionality
arm: Add an RX8900 RTC to the ASpeed board

The imx25 chip provides 3 i2c buses, but they have all been named
"i2c", which makes it difficult to predict which bus a device will
be connected to when specified on the command line.
This patch addresses the issue by naming the buses uniquely:
i2c-bus.0 i2c-bus.1 i2c-bus.2

The QTest framework cannot check the state of named interrupts. This patch
adds support for them.
Read actions are via callbacks, which allows for pulsed interrupts
to be read (the polled method used for the unnamed interrupts
cannot read pulsed interrupts as the value is reverted before the
test sees the changes).

Some devices change their behaviour based on the state of their input GPIO
lines.
This patch allows testing of the variable behaviour by providing facilities
for the test to set the state of these GPIO lines.

From: Alastair D'Silva <alastair@d-silva.org>
This patch adds support for the Epson RX8900 I2C RTC.
The following chip features are implemented:
- RTC (wallclock based, ptimer 10x oversampling to pick up
wallclock transitions)
- Time update interrupt (per second/minute, wallclock based)
- Alarms (wallclock based)
- Temperature (set via a property)
- Countdown timer (emulated clock via ptimer)
- FOUT via GPIO (emulated clock via ptimer)
The following chip features are unimplemented:
- Low voltage detection
- i2c timeout
The implementation exports the following named GPIOs:
rx8900-interrupt-out
rx8900-fout-enable
rx8900-fout

qemu_irq values aren't necessarily boolean: you can
send integers down them if you want. This will break
that by squashing the value down to 0/1.
The on-the-wire protocol with IRQ/IRQ_NAMED doesn't
support reporting an integer value, but the old code
did at least not break the device even if it wasn't able
to report the value back to the test code accurately.

This function type gets used in several places, can we have
a typedef please? (Typedefs for functions should be of the
function type, not the function pointer, and CamelCase, eg
typedef uint64_t CPReadFn(CPUARMState *env, const ARMCPRegInfo *opaque);
which you then use with "CPReadFn *readfn;".)

Should be int, see above; this then matches the int_levels[]
array it's replacing.

I still think this is wrong, I'm afraid. The GPIO line is
already connected to something else in the simulation,
and injecting a value that didn't come from whatever else
it's connected to is likely to confuse things.
Tests should work by programming the device that is connected
to the other end of this GPIO to make it raise the line.

You seem to be using time_altered to track state within the device
which persists between guest operations, which I think means it
needs to be in the vmstate -- consider the case of a migration
after the guest has done I2C_START_RECV but before it does
I2C_FINISH.
Alternatively: our other RTC models don't need this time_altered
flag, so why is this RTC different?

I think this is going to mean we don't get the RTC's
behaviour entirely right (for instance its idea of
leap years is simply "divisible by 4" rather than
the actual leap year definition). Looking at the
mc146818rtc model for instance we only seem to look at
the host's idea of the current time on device realize.

Rather than handling all these aliased registers by having to
remember to update them every time the code writes new values
into them, I think it would be better to special case the
two places in the code where we handle guest reads and writes
(rx8900_send and rx8900_recv) to do
nvram_offset = s->nvram_offset;
if ((nvram_offset >= 0x10 && nvram_offset <= 0x16) ||
(nvram_offset >= 0x1B)) {
/* registers 0x10..0x16 and 0x1B..0x1F are aliases of
* 0x00..0x06 and 0x0B..0x0F
*/
nvram_offset &= 0xf;
}
I think that will be less error-prone overall because the
aliasing is now handled in fewer places so updates to the
code are less likely to get it wrong.

I don't understand the INVALID_WEEKDAY logic. We set s->weekday
to INVALID_WEEKDAY here and in device reset, but there is no
code that I can see which checks whether the weekday value is
invalid and updates it.

You really don't want to model this like this. The hardware
may work by "every second (or more often) see if we need
to update something", but that makes for poor performance
in an emulator. What you should do is calculate in advance
the next time when you need to fire an interrupt, and
set up a timer to fire at that point. Then only actually
update your internal state when the timer fires, or if the
guest asks to read or write a register.

Directly modelling a 32kHz output pin by actually trying
to toggle a qemu IRQ at 32kHz is also going to really
hurt performance. The simple approach is not to bother
modelling this: do you really need it?. Otherwise you're
going to want to model something which actually tells
the other end "this is a clock signal at frequency f
which is currently enabled/disabled", and allow the
other end to sort itself out accordingly. The stuff that
Fred Konrad posted recently about clock tree modelling
may be relevant here.
