This patch series implements the nRF51 DETECT signal in the GPIO peripheral. A qtest is added exercising the signal.
To implement the test, named out-GPIO IRQ interception had to be added to the qtest framework. I also took the opportunity to improve IRQ interception a bit by adding 'FAIL' responses when interception fails. Otherwise, it is frustrating to troubleshoot why calls to qtest_irq_intercept_out and friends appears to do nothing. v1: https://patchwork.kernel.org/project/qemu-devel/list/?series=766078 Testing ======= Passes 'make check' Changelog ========= v2: factor out qtest_install_gpio_out_intercept before usage (Peter) renamed qtest_install_gpio_out_intercepts => qtest_install_gpio_out_intercept don't pass DETECT to soc level (Peter) change qtest to use DETECT at GPIO level (Peter) Chris Laplante (6): hw/gpio/nrf51: implement DETECT signal qtest: factor out qtest_install_gpio_out_intercept qtest: implement named interception of out-GPIO qtest: bail from irq_intercept_in if name is specified qtest: irq_intercept_[out/in]: return FAIL if no intercepts are installed qtest: microbit-test: add tests for nRF51 DETECT hw/gpio/nrf51_gpio.c | 14 ++++++++- include/hw/gpio/nrf51_gpio.h | 1 + softmmu/qtest.c | 56 ++++++++++++++++++++++++++---------- tests/qtest/libqtest.c | 6 ++++ tests/qtest/libqtest.h | 11 +++++++ tests/qtest/microbit-test.c | 42 +++++++++++++++++++++++++++ 6 files changed, 114 insertions(+), 16 deletions(-) -- 2.41.0
