h2. Agenda for Friday Meeting (Core + IO)
h3. 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
