Because PLAT_SAMSUNG isn't include exynos SoCs for arm64, but
ARCH_EXYNOS can do it. And it also needs to add ARCH_S3C64XX instead of
PLAT_SAMSUNG.

Drivers should use %p for printing pointers instead of hardcoding them
as hexadecimal integers. This patch fixes compilation warnings on 64bit
architectures.

I don't oppose the patch itself but I have different concern. First -
probably you meant %pK because this is a writeable structure with
function pointers.
Second - why the ippdrv has to be printed? Is it useful for debugging?
Best regards,
Krzysztof

Marek fixed just compilation warnings on ARM64 so yes it wouldn't need to print out ippdrv address but as other cleanup patch.

Another patch?
There is no point in a flow like this:
1. Make a patch which changes %x to %p.
2. Make a second patch right after the first one which changes %p to %pK.
3. Optionally make a third patch removing %pK entirely.
There are two issues here (and in other places like in patch 3/10) -
64bit compilation warnings and security related issues. Properly fixing
security related issues would fix in the same time the compilation
warnings...
Best regards,
Krzysztof

This patch fixes compilation warnings (on 64bit architectures) and bugs
related to casting pointers through 32bit integers.

MIC is SoC component and important part of kms pipeline on Exynos5433,
so convert it to use component framework like other KMS/CRTC drivers.
MIC driver is already listed on KMS component driver list in Exynos DRM
core, so without this conversion, initialization of Exynos DRM core
fails on Exynos 5433 SoC.

This patch fixes issue introduced by commit
cf67cc9a29ac19c98bc4fa0e6d14b0c1f592d322 ("drm/exynos: remove struct
exynos_drm_display"), which removed assigning of drm bridge to drm
encoder. Lack of it caused that no bridge callbacks were called on
encoder enable/disable actions.

Virtual DRM device is used for memory allocation for GEM objects. On
some architectures null dma operations are assigned for virtual devices

As you got the report, above function incurrs build error below,
ERROR: "arch_setup_dma_ops" [drivers/gpu/drm/exynos/exynosdrm.ko] undefined!
Exynos drm can be built as a module. In this case, arch_setup_dma_ops cannot be accessed by the module.
I could fix it easily like below but I'm not sure that it's reasonable.
+extern void arch_setup_dma_ops(struct device *dev, u64 dma_base,
+ u64 size, struct iommu_ops *iommu,
+ bool coherent) { };
Thanks,

I don't think this is a good idea - the result will be same as not applying
the patch at all. Please drop this patch for now, I will rework it while
adding support for generic IOMMU for ARM and ARM64.

Patch ebf3fd403b79ba6561bd1a4bb5a7cacc99da08e5 ("drm/exynos: add
pm_runtime to DECON 5433") removed some code from decon_enable()
function, but it left set_bit(BIT_SUSPENDED, &ctx->flags) call, which
was earlier called only in error path. This patch removes it, what
finally lets driver to go out of suspended state.

BIT_IRQS_ENABLED was never set because of incorrect test in
decon_vlank_enable() function, what resulted in lack of enabling vblank
support. This patch fixes this issue.

As you mentioned "64bit Exynos" devices, I'm wondering if you'll have
some input on the current exynos drm ABI as mentioned here [1]. I.e.
it feels broken when using 32bit userspace on 64 bit kernel due to the
use of unsigned int and alike types. Should we replace them (fix
things) with explicitly sized ones - _u32/64.
Does that sound reasonable, is anyone from the Exynos team interested
in sorting it out ?
Regards,
Emil

I will take care of it.
Thanks of pointing it out.
