The HIGHMEM zone starts at 0x30000000 -(768MB), and allowing the CMA zone to overlap that area causes a -failure during CMA activation. - -Avoid the overlap by limiting CMA to the first 768MB. This is overly -restrictive on a 64-bit kernel, but shouldn't cause any practical -problems. - -Signed-off-by: Phil Elwell <phil@raspberrypi.com> ---- - arch/arm/boot/dts/bcm2711-rpi.dtsi | 5 +++++ - 1 file changed, 5 insertions(+) - ---- a/arch/arm/boot/dts/bcm2711-rpi.dtsi -+++ b/arch/arm/boot/dts/bcm2711-rpi.dtsi -@@ -45,6 +45,11 @@ - }; - }; - -+&cma { -+ /* Limit cma to the lower 768MB to allow room for HIGHMEM on 32-bit */ -+ alloc-ranges = <0x0 0x00000000 0x30000000>; -+}; -+ - &soc { - thermal: thermal@7d5d2200 { - compatible = "brcm,avs-tmon-bcm2711"; |
