Hello Marcin, Thanks for the feedback. On Tue, 30 Oct 2018 13:37:37 +0100, Marcin Wojtas wrote:
You use _really_ archaic firmware, the bug you see is 99% caused by a bug already fixed long time ago (cleanup all PP2 BM pools correctly during exit boot services). Please grab the latest release: https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/wiki/files/flash-image-18.09.4.bin and let know if you observe any further issues with vanilla kernel.
Even if this was a bug in the UEFI firmware, shouldn't the kernel be independent from that, by doing a proper reset/reinit of the HW ? I.e, isn't the firmware fix papering over a bug that should be fixed in Linux mvpp2 driver anyway ?
