Core + +* ATF: +** Document installation procedure at elinux.org wiki +** Configure from DTS +** UBoot and ATF could be built through CI and tested. +*** e.g. https://travis-ci.org/marex/arm-trusted-firmware-1/builds/485750085 +*** https://docs.travis-ci.com/user/uploading-artifacts/ for prebuilt binaries ? + +* U-Boot: MMC HS200/HS400 and SD SDR104 issues. +** Playing whack-a-mole with bug fixes. +** Testing identified bugs in core U-Boot MMC code which is being explored and fixed. + +* OpenOCD +** Kernel awareness patches for GDB are progressing *SLOWLY*. +** A Latest RFC is posted by Linaro: +*** https://sourceware.org/ml/gdb-patches/2019-01/msg00596.html + +* BSP +** List is reducing for two reasons +*** We've got stuff done +*** BSP is filtered to priorities. + +* Upstream + Maintainers are happy. Renesas is seen as the 'second' best upstreaming ARM-SoC. + The first is ATMEL which is so small it's incomparable - they have less work to do :) + +* CPUidle: +** Get clarification of real issues (SYSC CPU/GSX concurrency?) +** Enable when we get newer SoC revisions where the hardware has been fixed + +* IPMMU +** Unusable on H3 before ES3.x.. +** E3/M3 might be OK (because they are newer) +** 32-bits IOVA space status? Discuss at Sundays IPMMU chat + +* TEE +** Coordinate between optee os and Linux -> Marek? + +* 32-bit DMA limitation on arm64 fixed upstream? + +* Gen3 TDSEL: +** Assumption: (1) reset state or (2) value programmed by bootloader is OK +** (2) => Add register to list of registers to save/restore during suspend/resume +** Describe TDSEL value in DT? + +* Patchwork and automatic status updates. +** Patchwork now has automatic filters to delegate to Geert / Horms / Kbingham +** A few false positives on the rules, but otherwise helpful. +** New rules to catch missing corners. +** Horms to suggest any extra rules to match maintained files +** KB to request automatic patchwork update tool against linux-next. + + +h3. IO + +* plan next tasks +* sync SDHI experiences (esp. Linux / U-Boot) +* [[upstream design for complex GMSLish I2C setups]] + +http://muistio.tieke.fi/p/PeriPeriBE + +h2. Agenda for Sunday Meeting (global & casual) + +* IPMMU (moved to Global due to Magnus' availability) +** What is the performance impact of enabling the IPMMU? +*** Needs benchmarking +*** IPMMU may not be useful for boards with less than 4 GiB of RAM + +* Periject +# Missing feature is automatic ID generation +*** To be implemented (on client) +# Run scripts to populate database from older data +# Go life +# Profit! ;-) + +* Discussion about future plans +** R-Car H3-N: No new information +** Virtualization: No feedback from Renesas + +h2.
