Since it's rightly frowned upon adding such boolean-quirk-properties to upstream devicetrees, we'd at least need additional (fallback-) compatibles, even if it works with the iommu driver as is (what I doubt, but haven't tested). We need to be able to apply those quirks later without changing the devicetree (as usual) and I'm sure RK devs haven't added these quirks for the personal amusement. If Detlev says iommu is out of scope for this series (which is valid), I'd say it's fine to leave them out for now (as no binding exists) and the HW works (obviously) fine without them. > Regards, > Jonas > >> }; >> >> #include "rk3588s-pinctrl.dtsi"

Based on what I investigated the hw should work similar, and the quirks mostly seem related to optimizations and sw quirks, like do not zap each line, keep it alive even when pm runtime say it is not in use and other quirks that seem to be more of sw nature on how to best utilize the hw. > If Detlev says > iommu is out of scope for this series (which is valid), I'd say it's fine > to leave them out for now (as no binding exists) and the HW works > (obviously) fine without them.

This may be something I'm doing wrong, but it clearly needs more > investigation. I re-tested and the addition of sram seem to now cause page faults, the sram also need to be mapped in the iommu. However, doing more testing revealed that use of iommu present the same issue as seen with hevc on rk3399, after a fail fluster tests continue to fail until a reset. Seeing how this issue was very similar I re-tested on rk3399 without iommu and cma=1G and could observe that there was no longer any need to reset after a failed test. Interestingly the score also went up from 135 to 137/147. Digging some more revealed that the iommu also is reset during the internal rkvdec soft reset on error, leaving the iommu with dte_addr=0 and paging in disabled state. Ensuring that the iommu was reconfigured after a failure fixed the issue observed on rk3399 and I now also get 137/147 hevc fluster score using the iommu. Will send out a rkvdec hevc v2 series after some more testing. Guessing there is a similar need to reconfigure iommu on rk3588, and my initial tests also showed promising result, however more tests are needed.

I did some testing with the IOMMU. The good news is that it now works with the SRAM. I am also able to hack the iommu driver to force a reset in case of an error in the decoder. I'm not sure how to implement that with the IOMMU kernel API though. Another issue is that resetting the iommu will drop all buffer addresses of other decoding contexts that may be running in parallel. I *think* that the downstream mpp remaps the buffers in the iommu for each frame, but I'm not sure about that either. So running fluster with `-j 1` gives me the expected 129/135 passed tests, but `-j 8` will start failing all tests after the first fail (well, first fail because of decoder error). > Regards, > Jonas > > >>> If Detlev says > >>> iommu is out of scope for this series (which is valid), I'd say it's > >>> fine > >>> to leave them out for now (as no binding exists) and the HW works > >>> (obviously) fine without them. > >> > >> Sure, use of MMU can be added later. > > > > I'd rather go for that for now.

I am planning on sending something along the way of this as an RFC: https://github.com/Kwiboo/linux-rockchip/compare/6da640232631...bf332524d880 If we re-configure and re-enable the iommu just before next decoding run after a decoding has failed seem to resolve any issue I have seen, have mainly been tested with rkvdec and HEVC on RK3399/RK3328.

This was the main issue blocking rkvdec hevc, just re-confgure the mmu after a frame fails to decode seem to resolve this issue. Biggest issue at the moment is how to properly signal iommu subsystem that it should re-configure, I may have abused the flush_iotlb_all ops, since that seemed closest existing hook. Will send an RFC to linux-iommu to collect input on how to best signal iommu subsystem that the mmu has been reset by an external event and now need to be re-configured.

Oh I see, it just resets the iommu config in the core's registers, but the hardware retains the mapped addresses. That makes things simpler indeed, just reconfigure before the next frame in case of status error in the interrupt. > > I *think* that the downstream mpp remaps the buffers in the iommu for each > > frame, but I'm not sure about that either. > > As long as a frame can be decoded correctly, the mmu config seem to continue > to be valid and next frame can be decoded. > > > So running fluster with `-j 1` gives me the expected 129/135 passed tests, > > but `-j 8` will start failing all tests after the first fail (well, first > > fail because of decoder error). > > This was the main issue blocking rkvdec hevc, just re-confgure the mmu > after a frame fails to decode seem to resolve this issue. > > Biggest issue at the moment is how to properly signal iommu subsystem that > it should re-configure, I may have abused the flush_iotlb_all ops, since > that seemed closest existing hook. Oh I see, I was wondering what the flush_iotlb_all ops was doing exactly. So does it flush a "cached" copy of the table from the driver back to the hardware ? As well as reconfigure the registers I guess. > Will send an RFC to linux-iommu to collect input on how to best signal > iommu subsystem that the mmu has been reset by an external event and now > need to be re-configured.
