| With the current range specified for the CPU interface there is an | ||
| error message at boot: | ||
|
|
||
| GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set | ||
|
|
||
| Setting irqchip.gicv2_force_probe=1 in bootargs results in: | ||
|
|
||
| GIC: Aliased GICv2 at 0x0000000010320000, trying to find the canonical range over 128kB | ||
| GIC: Adjusting CPU interface base to 0x000000001032f000 | ||
| GIC: Using split EOI/Deactivate mode | ||
|
|
||
| Using the adjusted CPU interface base and 8K size results in only the | ||
| final line remaining and fully working system as well as /proc/interrupts | ||
| showing additional IPI3,4,5,6: | ||
|
|
||
| IPI3: 0 0 CPU stop (for crash dump) interrupts | ||

| The MT7622 device tree never bothered to specify the number of virtual DMA | ||
| channels for the HSDMA controller, always falling back to the default value of | ||
| 3. Make this value explicit, in order to avoid the following dmesg notification: | ||
|
|
||
| mtk_hsdma 1b007000.dma-controller: Using 3 as missing dma-requests property | ||
