This patch adds a new STM32L4x5 EXTI device and is part of a series implementing the STM32L4x5 with a few peripherals.
The patch is split up in 3 commits : - implementing the EXTI device - adding tests (that fail in this commit) - connecting the EXTI device to the SoC (the tests pass in this commit) Thank you Alistair for the review and very helpful answers ! Sincerely, Ines Varhol Changes from v3 to non-RFC v1: - separating the patch in 3 commits - justifying in the commit message why we implement a new model instead of changing the existing stm32f4xx_exti - changed irq_raise to irq_pulse in register SWIERx write (in stm32l4x5_exti_write) to be consistent with the irq_pulse in stm32l4x5_exti_set_irq (and also both these interrupts are edge-triggered) - changed the license to GPL Changes from v2 to v3: - adding more tests writing/reading in exti registers - adding tests checking that interrupt work by reading NVIC registers - correcting exti_write in SWIER (so it sets an irq only when a bit goes from '0' to '1') - correcting exti_set_irq (so it never writes in PR when the relevant bit in IMR is '0') Changes from v1 to v2: - use arrays to deduplicate code and logic - move internal constant EXTI_NUM_GPIO_EVENT_IN_LINES from the header to the .c file - Improve copyright headers - replace static const with #define - use the DEFINE_TYPES macro - fill the impl and valid field of the exti's MemoryRegionOps - fix invalid test caused by a last minute change Based-on: <170100975340.4879.584410848409211113...@git.sr.ht> ([PATCH qemu 0/2] hw/arm: Add minimal support for the B-L475E-IOT01A board) Inès Varhol (3): hw/arm: Implement STM32L4x5 EXTI hw/arm: Add STM32L4x5 EXTI QTest testcase hw/arm: Connect STM32L4x5 EXTI to STM32L4x5 SoC hw/arm/Kconfig | 1 + hw/arm/stm32l4x5_soc.c | 65 +++- hw/misc/Kconfig | 3 + hw/misc/meson.build | 1 + hw/misc/stm32l4x5_exti.c | 299 ++++++++++++++++++ hw/misc/trace-events | 5 + include/hw/arm/stm32l4x5_soc.h | 3 + include/hw/misc/stm32l4x5_exti.h | 61 ++++ tests/qtest/meson.build | 5 + tests/qtest/stm32l4x5_exti-test.c | 485 ++++++++++++++++++++++++++++++ 10 files changed, 926 insertions(+), 2 deletions(-) create mode 100644 hw/misc/stm32l4x5_exti.c create mode 100644 include/hw/misc/stm32l4x5_exti.h create mode 100644 tests/qtest/stm32l4x5_exti-test.c -- 2.38.5
