f7606400f19ca0291718ce4eed5770798890ea2f - dma-buf: move system_cc_shared heap under separate Kconfig

Wed, 10 Jun 2026 16:23:29 +0200

dma-buf: move system_cc_shared heap under separate KconfigWhile system heap and system_cc_shared heap share a lot of codeand hence the same source file, their users have different needs.system heap users need it to be a loadable module, whilesystem_cc_shared heap users don't.Building as a loadable module breaks system_cc_shared heap onpowerpc and s390 due to un-exported set_memory_encrypted /set_memory_decrypted functions.Fix these by reorganising code to put the system_cc_shared heapunder a new Kconfig symbol, which allows either building bothinto the kernel, or leave encryption up to the consumers of thesystem heap.Fixes: fd55edff8a0a ("dma-buf: heaps: system: Turn the heap into a module")Signed-off-by: Arnd Bergmann Signed-off-by: Sumit Semwal [sumits: updated DMABUF_HEAPS_CC_SYSTEM to DMABUF_HEAPS_SYSTEM_CC_SHARED]Reviewed-by: T.J.

Mon, 13 Oct 2025 10:35:20 +0200

dma-buf: heaps: cma: Create CMA heap for each CMA reserved regionAside from the main CMA region, it can be useful to allow userspace toallocate from the other CMA reserved regions.Indeed, those regions can have specific properties that can be useful toa specific us-case.For example, one of them platform I've been with has ECC enabled on theentire memory but for a specific region. Using that region to allocateframebuffers can be particular beneficial because enabling the ECC has aperformance and memory footprint cost.Thus, exposing these regions as heaps user-space can allocate from andimport wherever needed allows to cover that use-case.For now, only shared-dma-pools regions with the reusable property (ie,backed by CMA) are supported, but eventually we'll want to support otherDMA pools types.Since we collected all the CMA regions created during boot, we cansimply iterate over all of them to create the heaps.This has a weird interaction with the recent work on the CMA name, inparticular the backward compatibility code created by commit854acbe75ff4 ("dma-buf: heaps: Give default CMA heap a fixed name").Indeed, the old name was either 'reserved', or the name of thereserved-memory region device tree node if the linux,cma-defaultproperty was set.In both these cases, we have now collected this region during boot, andwe're using the same name. So we're now largely redundant with thecode to handle backward compatibility code, and we can thus remove itand the associated Kconfig option.Reviewed-by: T.J.
