Hi,
I am running arm-trusted-firmware on Juno and when I breakthrough DS-5 on EL3 level I see FIQ pending status in ISR_EL1.
I am trying to bring-up linux guest OS and when I try to run linux image I am entering virtual FIQ handler at EL2 level.
Please let me know if there is any way I can ignore this FIQ pending ?
I tried using GICC_CTLR and GICV_CTLR registers bit 0 to disable Group0 (FIQs) interrupts but it is not helping.
Thanks,
Hi Matt,
After finding out the FIQBypDisGrp0 [5] bit now I am setting GICC_CTLR 0x220 but still I end up going to vFIQ handler in EL2 mode.
So bit Group0[0] and FIQEn[3] are disabled and also Bypass is disabled. Not sure what might be missing.
Thanks
