QCLINUX: qcom.config: enable CONFIG_CMA for qcom chipsets by bibekpatro · Pull Request #552 · qualcomm-linux/kernel

bibekpatro · 2026-05-08T08:38:59Z

CMA imposes system-wide memory constraints by reserving boot-time memory and restricting it to movable allocations. This alters allocator behavior even when CMA is not explicitly used. Since CMA sizing and applicability are platform-specific, mm/Kconfig intentionally provides no default opt-in for CONFIG_CMA.

Enable CONFIG_CMA for all qcom chipsets
