* media: verisilicon: change confusingly named relaxed register accessArnd Bergmann2023-07-142-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | The register abstraction has wrappers around both the normal writel() and its writel_relaxed() counterpart, but this has led to a lot of users ending up with the relaxed version. There is sometimes a need to intentionally pick the relaxed accessor for performance critical functions, but I noticed that each hantro_reg_write() call also contains a non-relaxed readl(), which is typically much more expensive than a writel, so there is little benefit here but an added risk of missing a serialization against DMA. To make this behave like other interfaces, use the normal accessor by default and only provide the relaxed version as an alternative for performance critical code. hantro_postproc.c is the only place that used both the relaxed and normal writel, but this does not seem cricital either, so change it all to the normal ones.

* media: verisilicon: fix excessive stack usageArnd Bergmann2023-07-141-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | In some configurations, gcc decides not to inline the register accessor functions, which in turn leads to lots of temporary hantro_reg structures on the stack that cannot be eliminated because they escape into an uninlined function: drivers/media/platform/verisilicon/rockchip_vpu981_hw_av1_dec.c:1022:1: warning: the frame size of 1112 bytes is larger than 1024 bytes [-Wframe-larger-than=] Mark all of these as __always_inline so the compiler is able to completely eliminate the temporary structures instead, which brings the stack usage back down to just the normal local variables.

* media: mediatek: vcodec: fix cancel_work_sync fail with fluster testYunfei Dong2023-07-141-1/+2

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The mtk8195_jpegenc_drvdata object was added outside of an #ifdef causing a harmless build warning. drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.c:1879:32: error: 'mtk8195_jpegenc_drvdata' defined but not used [-Werror=unused-variable] 1879 | static struct mtk_jpeg_variant mtk8195_jpegenc_drvdata = { | ^~~~~~~~~~~~~~~~~~~~~~~ A follow-up patch moved it inside of an #ifdef, which caused more warnings, and a third patch ended up adding even more #ifdefs. These were all bogus, since the actual problem here is the incorrect use of of_ptr(). Since the driver (like any other modern platform driver) only works in combination with CONFIG_OF, there is no point in hiding the reference, so just remove that along with all the pointless #ifdef checks in the driver. This improves build coverage and avoids running into the same problem again when another part of the driver gets changed that relies on the #ifdef blocks to be completely matched.
