Libmali with Vulkan support for RK3588 (mali G610) #21

Closed vassad closed 6 months ago

vassad commented 6 months ago

Hello!

I have a question about https://github.com/tsukumijima/libmali-rockchip.git (this repo, branch libmali): I use OrangePi5B device, trying to build on Ubuntu for -Dplatform=vulkan with error: The Meson build system Version: 0.61.2 Source dir: /home/orangepi/git/libmali-rockchip Build dir: /home/orangepi/git/libmali-rockchip/build Build type: native build Project name: libmali Project version: 1.9.0 C compiler for the host machine: cc (gcc 11.4.0 "cc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0") C linker for the host machine: cc ld.bfd 2.38 Host machine cpu family: aarch64 Host machine cpu: aarch64 Message: Building for aarch64|valhall|g610|g13p0|vulkan|O3 meson.build:40:2: ERROR: Problem encountered: Failed to find matched library

As i understand, i need a prebuilt library like libmali-valhall-g610-g13p0-vulkan-gbm.so in lib/ folder? If so, where can i take it/build it? If i build with this command: meson build . -Dgpu=valhall -Dversion=g610 -Dsubversion=g13p0 -Dplatform=x11 Everything is fine, EXCEPT this: Checking for function "vk_icdGetInstanceProcAddr" with dependency -lmali-prebuilt: NO

T620 seems to work with vulkan cause of data/mali.json.in commit with confirmation that it works correctly. "Tested with an internal version of DDK for vulkan, vulkaninfo works."

Best regards, Vadim.

Sorry, i don't know much about that, the mali DDK is maintained by the RK GPU team internally, it seems like the vulkan library has not yet released.

If you want to know the release schedule, maybe try to mail the maintainers(the committers of the related libraries)

Ok, thanks very much! BTW Android version of Mali with Vulkan is definitely working cause ncnn benchmark with gpu support is uploaded here: https://github.com/Tencent/ncnn/tree/master/benchmark#rockchip-rk3588-cortex-a76-24ghz-x-4--cortex-a55-18ghz-x-4

right, it has different backends, the local version i used to test was drm(kms) backend.

so right now it is possible to use mali with vulkan but only on Android?

JeffyCN commented 6 months ago

i don't know the release schedule, the code for drm backend should be ready (at least i've tested it locally long time ago)
