I am not sure how AER should be integrated
<vigneshr>
austriancoder: I have asked pcie expert internally to help out. but AFAIK drivers/pci/pcie/aer.c should take care of AER - > aer_probe() has IRQ handling et al. I have no idea on how to get the service driver probed and pick up irq from DT
<austriancoder>
vigneshr: thanks for asking.. yeah.. I had the same feeling about AER that the portdriver should be used. Lets see what I can find out
<austriancoder>
NishanthMenon: is there a way to detect/readout how many a53 cores are available?
<NishanthMenon>
austriancoder: in spl or kernel?
<austriancoder>
NishanthMenon: in spl or proper U-Boot would be great so that I can patch the fdt

wonders if jtag_user_id has information
<NishanthMenon>
that is nice, did'nt know the elaboration in DEVICE_FEATURESx register (in hindsight, duh!)
<vigneshr>
austriancoder: looks like AER should just work over MSI and don't really need wired IRQ. pcie_port_device_register() -> should discover AER caps and register aer_isr() . All looks platform agnostic ?

vigneshr: pcieport 0000:00:00.0: AER: enabled with IRQ 318
<austriancoder>
but something like this is not needed? j721e_pcie_intd_writel(pcie, ENABLE_REG_SYS_2, reg);
<austriancoder>
NishanthMenon: thanks .. will have a look
