09:22 <rozpruwacz> _florent_: I looked into GPIOIn interrupt thing which You updated lately. I have trouble building the soc. I cannot add GPIOIn interrupt to the soc. After adding GPIOIn module (self.submodules.switches = GPIOIn(switches_pads, with_irq=True)) I do self.add_csr("switches") and then self.irq.add("switches", use_loc_if_exists=True). But the last part fails during build process with error "ERROR:SoC:EventManager not found in switches SubModule

09:22 <rozpruwacz> ". I think the problem is that the EventManager is now a submodule of _GPIOIRQ which in turn is a submodule of GPIOIn - before the EventManager was a submodule of GPIOIn directly. How to handle this situation ?

09:27 <_florent_> rozpruwacz: Hi, can you try this?:

10:10 <rozpruwacz1> _florent_: soc builds now correctly (not tested on hardware yet) but the bios software is failing. Software generation causes multiple definitions of CSR_SWITCHES_EV_EV_STATUS_ADDR, switches_ev_ev_status_read and others in include/generated/csr.h:

10:10 <rozpruwacz1> #define CSR_SWITCHES_EV_EV_STATUS_ADDR (CSR_BASE + 0x580cL)

10:10 <rozpruwacz1> #define CSR_SWITCHES_EV_EV_STATUS_ADDR (CSR_BASE + 0x5808L)

10:10 <rozpruwacz1> #define CSR_SWITCHES_EV_EV_STATUS_ADDR (CSR_BASE + 0x580cL)

10:10 <rozpruwacz1> #define CSR_SWITCHES_EV_EV_STATUS_ADDR (CSR_BASE + 0x5808L)

10:11 <_florent_> rozpruwacz1: ok sorry, I'll have a closer look

16:04 <rozpruwacz1> _florent_: I have tested GPIOIn on hardware and axcept the bios software the HDL part works as expected.Also I have updated linux driver with lates changes and I will soon publish a pull request. I think that the GPIOInOut also could have with_irq parameter passed to its GPIOIn submodule - the register layout of GPIOInOut makes it compatible with linux driver (assuming separate device tree nodes for in and out). I don't know what to do wi

16:04 <rozpruwacz1> th GPIOTristate though ... If it would have register layout compatible with GPIOIn and GPIOOut then it would be easy to include it in the linux driver.

16:11 <rozpruwacz> Oh, and the GPIOTristate do not compile under quartus.
