Re: [coreboot] how to route IRQ4 (COM1) on LPC bus for bayleybay_fsp

Yep, I think it should be great to have these options available in Kconfig. SETUPSERIQ should be transform to CONFIG_SETUPSERIQ. CONFIG_SERIRQ_CONTINUOUS_MODE is very important when SERIRQ is activated to avoid spurious interrupt and other mysterious LPC IRQ issues. Thanks Benoit -- coreboot

Re: [coreboot] how to route IRQ4 (COM1) on LPC bus for bayleybay_fsp

Everything works right now. I explained and tested it at http://www.coreboot.org/pipermail/coreboot/2016-January/080845.html FYI, I activated the SERIRQ in file src/soc/intel/fsp_baytrail/southcluster.c by defining SETUPSERIQ and CONFIG_SERIRQ_CONTINUOUS_MODE in my Kconfig in my mainboard folder.

Re: [coreboot] how to route IRQ4 (COM1) on LPC bus for bayleybay_fsp

Hi, As explained in my post, I am not using the UART located in the Baytrail SOC. I used an SIO for serial line connected to the LPC bus. So to have the IRQs of these serial lines, I obviuosly need to SERIRQ. The IRQEN is only for the COM1 located in the SOC. Thanks for your help Benoit On

Re: [coreboot] how to route IRQ4 (COM1) on LPC bus for bayleybay_fsp

Hi I mean by not available : not working under my real time OS that I load through a grub2 paylaod. You are right. I replace the IRQ 4 by an other one that it is not used in my system as follow : #define PIRQ_PIC_ROUTES \ PIRQ_PIC(A, 5), \ PIRQ_PIC(B, 6), \ PIRQ_PIC(C,

[coreboot] how to route IRQ4 (COM1) on LPC bus for bayleybay_fsp

Hi all, I am currently running coreboot + fsp on a E3837 cpu based platform. My platform has serial line in a LPC device. Firstly, I activated the SERIRQ in continous mode. Nevertheless under operating system, the IRQ4 for COM1 is not available. I checked out the file

Re: [coreboot] how to route IRQ4 (COM1) on LPC bus for bayleybay_fsp

Hi What does it mean not available? Maybe you can check if you programmed ELCR register to edge for IRQ4. You can't share the IRQ4 with PCI IRQ I think thats why it does not work. You need to route the the PIRQA to something else, like IRQ3. Thanks Rudolf -- coreboot mailing list:
