* drm/mediatek: Support MT8188 Padding in display driverHsiao Chien Sung2023-12-145-2/+168
| | | | | | | | | | | | | | | Padding is a new display module on MT8188, it provides ability to add pixels to width and height of a layer with specified colors. Due to hardware design, Mixer in VDOSYS1 requires width of a layer to be 2-pixel-align, or 4-pixel-align when ETHDR is enabled, we need Padding to deal with odd width.

* drm/mediatek: Power on/off devices with function pointersHsiao Chien Sung2023-12-146-20/+107
| | | | | | | | | | | | | | | | | | Different from OVL, OVL adaptor is a pseudo device so we didn't define it in the device tree, consequently, pm_runtime_resume_and_get() called by .atomic_enable() powers on no device. For this reason, we implement a function to power on the RDMAs in OVL adaptor, and the system will make sure the IOMMUs are powered on as well because of the device link (iommus) in the RDMA nodes in DTS. This patch separates power and clock management process, it would be easier to maintain and add extensions.

* drm/mediatek: Add component ID to component match structureHsiao Chien Sung2023-12-141-39/+30
| | | | | | | | | | | | | | | | | | | | Add component ID to component match structure so we can configure them with a for-loop. The main reason we do such code refactoring is that there is a new hardware component called "Padding" since MT8188, while MT8195 doesn't have this module, we can't use the original logic to manage the components. While MT8195 does not define Padding in the device tree, the corresponding components will be NULL and being skipped by the functions.

If an IOMMU is providing transparent DMA API ops for any device(s) we care about, the DT code will have enforced the appropriate probe ordering already. And if the IOMMU *is* entirely absent, then attempting to go ahead with CMA and either suceeding or failing decisively seems more useful than deferring forever.

If these functions are not inlined (which the compiler is free to do even with functions marked with the standard 'inline' keyword), the BUILD_BUG() in the default case cannot be eliminated since the compiler cannot prove it is never used, resulting in a build failure due to the error attribute. Mark these functions as __always_inline to guarantee inlining so that the BUILD_BUG() only triggers when the default case genuinely cannot be eliminated due to an unexpected size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The distance between vmlinux and the module is too far so that PC-REL cannot be accessed directly, only GOT. When compiling module with GCC, the option `-mdirect-extern-access` is disabled by default. The Clang option `-fdirect-access-external-data` is enabled by default, so it needs to be explicitly disabled.

In some recent examples this turned out to be a significant problem when trying to analyze performance data - since there are many cases where unless we know the tree id and session id we can't figure out which stats (e.g. number of SMB3.1.1 requests by type, the total time they take, which is slowest, how many fail etc.) apply to which mount. The only existing loosely related ioctl CIFS_IOC_GET_MNT_INFO does not return the information needed to uniquely identify which tcon is which mount although it does return various flags and device info. Add a cifs.ko ioctl CIFS_IOC_GET_TCON_INFO (0x800ccf0c) to return tid, session id, tree connect count.
