Give me a second you have to make a few more changes to make it device tree aware
Pedro Henrique Penna
@ppenna
ok
I also need to informe the device node
how will I get that?

https://github.com/stffrdhrn/linux/blob/openrisc-4.13-smp-qspinlock/drivers/tty/serial/8250/8250_of.c
You can look at examples in the linux kernel
i.e.
static const struct of_device_id of_platform_serial_table[] = {
{ .compatible = "ns8250", .data = (void *)PORT_8250, },
There are probably much more simple cases
Ill join the call in a second
Pedro Henrique Penna
@ppenna
question:
whe we use DTS, do I need to ioremap_nocache()
Ghost
@ghost~5910ddcfd73408ce4f5dfa87
ompic_base = of_iomap(node, 0);
Ghost
@ghost~5910ddcfd73408ce4f5dfa87
node you get from
pdev->dev.of_node
Ghost
@ghost~5910ddcfd73408ce4f5dfa87
@ppenna re IRQ triggering, by default you will get the trigger mode of the IRQ controller. So I dont think you should change it at all.
Pedro Henrique Penna
@ppenna
how would I don't change it?
Ghost
@ghost~5910ddcfd73408ce4f5dfa87
Just remove it from the flags
Pedro Henrique Penna
@ppenna
moreover, to stop using DTS I should just remove it from the DTS file?
Ghost
@ghost~5910ddcfd73408ce4f5dfa87
Well, you are alreayd not using it. No harm keeping it in the DTS file
Pedro Henrique Penna
@ppenna
hmmm
ok
Ghost
@ghost~5910ddcfd73408ce4f5dfa87
We want to switch to DTS later
after you fix the driver as is, so keep it there
Pedro Henrique Penna
@ppenna
ok then
Pedro Henrique Penna
@ppenna
@imphil STM log does not work without crashing
how you I know that data is arriving in the COMPUTE tile?
I cannot simply printf()
because the UART termnal is beeing used...
Philipp Wagner
@imphil
So you enabled STM for the second tile with baremetal and the terminal for the first tile with linux and nothing else? And what's crashing then? opensocdebugd?
Pedro Henrique Penna
@ppenna
wow
WAIT
Pedro Henrique Penna
@ppenna
@imphil @stffrdhrn @wallento sending data from the HOST tile to the COMPUTE tile works
=D
Philipp Wagner
@imphil
Nice! Already a great step forward!
Stefan Wallentowitz
@wallento
nice
sorry, I was out during the call
Pedro Henrique Penna
@ppenna
=)
no problem.... I shall now try to fix the interrupts
Pedro Henrique Penna
@ppenna
@imphil could you or @wallento please push a "README" file on the https://github.com/optimsoc/linux-apps? Since there are no files in the repository I cannot clone it
Philipp Wagner
@imphil
@ppenna done
Pedro Henrique Penna
@ppenna
@imphil thank you! I'll submit a pull request for the linux-apps in a couple of ours
I've already submitted a patch for the optimsoc repo
Philipp Wagner
@imphil
@ppenna where did you submit the PR for optimsoc? https://github.com/optimsoc/optimsoc/pulls doesn't list it
Pedro Henrique Penna
@ppenna
I have send a PR for linux repô
Besides, have you receivd the link for my report?
Philipp Wagner
@imphil
ah ok, I'll look briefly through the PR, a more substantial review probably can be done by Stafford ahead of sending it to LKML
on the report, I'm looking through it right now
Pedro Henrique Penna
@ppenna
Ty... I still need to write the building and testing section... I should finish it after Lynch
Ler me know what are you expecting there, if anything especial
Philipp Wagner
@imphil
will do
