Subject: [PATCH] gpu/drm: Replace "%p" with "%pK"
Date: Tue, 30 Jun 2020 15:36:01 +0800
Message-ID: <1593502561-15190-1-git-send-email-yangtiezhu@loongson.cn> (raw)

When I update the latest kernel, I see the following "____ptrval____" boot
messages. Use "%pK" instead of "%p" so that the cpu address can be printed
when the kptr_restrict sysctl is set to 1.

Both radeon_fence_driver_start_ring() and amdgpu_fence_driver_start_ring()
have this similar issue, fix them.

[    1.872600] radeon 0000:01:05.0: fence driver on ring 0 use gpu addr 0x0000000048000c00 and cpu addr 0x(____ptrval____)
[    1.879095] radeon 0000:01:05.0: fence driver on ring 5 use gpu addr 0x0000000040056038 and cpu addr 0x(____ptrval____)
