From 274d586060ec240ad9a1424a21101765a5f8cff3 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Mon, 10 Feb 2020 21:51:46 +0100 Subject: [PATCH] package/mesa3d: fix circular dependency in Kconfig When the r300 driver was introduced in c5ae77c97 (package/mesa3d: add support for gallium r300 driver), a last-minute fix was introduced by Yann, to properly propagate the dependency of a selected symbol. However, this ended up causing a spurious circular dependency that does not really exists, but that Kconfig is not smart enough to detect is in fact OK. Fixing this is pretty non-obvious, but we have an easy way out: the dependency is about libdrm's radeon driver requirement for a toolchain that has the sync4 family of primitives, which is always a given for an x86 toolchain. As the radeon r300 driver is x86-only, this dependency is forcefully fulfilled. So, we drop the propagated dependency, and replace it by a fat comment. Signed-off-by: Yann E.
