[PATCH qemu 0/1] Implement the STM32L4x5 EXTI device

Posted by ~aminier 1 year ago

This patch allows to emulate the STM32L4x5 EXTI device.
It implements register access and software interruptions.

This is RFC since we had troubles to make all tests pass.
More precisely, the line `g_assert_true(get_irq(GPIO_0_IRQ));` fails in
the software interrupts test. No irq seems to be fired.
(We also tested the stm32f4_exti (on which this implementation is based
upon) on but it also fails so don't really know if the test or the
implementation is incorrect)

Based-on: <170049810484.22920.612074576971878323-0@git.sr.ht>
([RFC v3 2/2] hw/arm: Add minimal support for the B-L475E-IOT01A board)

(We got the message id from
https://patchew.org/QEMU/170047309499.17129.4986209009679789101-0@git.sr.ht/
but don't really the standard procedure to get it. Sorry if this is
incorrect.)

This is the correct tag and msg-id :)
