Re: Question about disable MMU in BL1

by 邬金平

Hi, I have tried this before, there is a problem. on Armv8, when MMU disabled, the default attribute of memory is device, and device memory access has alignment requirements. For example, accessing address (0x1) will result in fault.

Question about maximum TF-A BL31 memory usage

by Peng Fan

Hi All, Is there any public BL31 memory usage data, such as static image size and runtime memory usage, with different feature enabled? For example, typical PSCI feature would require image size XXKB, runtime memory XXKB. enabling FFA would enlarge image size by XXKB, runtime memory enlarge XXKB. we are evaluating how much On-Chip RAM could be assigned for BL31, if there are any public data available, that would be great. Thanks, Peng.

Rebooting LTS discussion

by Okash Khawaja

Hi, There have been discussions about having long term support releases for TF-A, e.g. the email thread [1] and a tech forum [2]. For partners releasing TF-A in their production devices, LTS is very much needed. From the previous discussions, it seems like there is an agreement that LTS is a good idea but we need to build consensus on how to support it. Any thoughts on this? Thanks, Okash [1] https://lists.trustedfirmware.org/archives/search?mlist=tf-a%40lists.truste… [2] https://www.trustedfirmware.org/docs/TF-A-LTS.pdf

Question about FVP's dts

by Chenxu Wang

Hi all, I am using FVP base RevC. Recently I heard that this FVP supports a Mali G76 GPU, and I want to test it. To configure it, initially I add a node in linux/arch/arm64/boot/dts/arm/fvp-base-aemv8a-aemv8a.dtsi, but it doesn't work. Finally, I find that I should configure trusted-firmware-a/fdts/fvp-base-gicv3-psci-1t.dts, and I can see a mali GPU node in /proc/device-tree. One of my booting command (sorry, the entire booting command is TOO long) is "--data cluster0.cpu0=arm-reference-platform/output/fvp/fvp-oe/uboot/fvp-base-aemv8a-aemv8a.dtb@0x82000000". And I use the following shell command to compile the TF-A: make PLAT=fvp all CROSS_COMPILE=aarch64-none-elf- ENABLE_RME=1 DEBUG=1 ARCH=aarch64 fip BL33=arm-reference-platform/output/fvp/components/fvp/uboot.bin FVP_HW_CONFIG_DTS=fdts/fvp-base-gicv3-psci-1t.dts ARM_DISABLE_TRUSTED_WDOG=1. So, I wonder, why the real DTS is in TF-A, instead of Linux? BTW, I wanna ask another question (although it is not proper to ask here, I cannot find FVP's mailing list): Can someone provide a proper dts configurations for FVP's Mali G76 GPU? Sincerely, WANG Chenxu

Re: Cannot successfully jump to the UEFI Boot Loader in the normal world with the RME enabled FVP_Base_RevC_2xAEMvA

by Erhu Feng

Hi, Thanks for the detailed documentation about how to enable RME in tf-a. I try to replace the tftf.bin with the normal boot firmware (edk2) to load the Linux in the normal world, but it fails. The log message from terminal_0 is shown below: INFO: RMM init start. INFO: RMM init end. INFO: BL31: Preparing for EL3 exit to normal world INFO: Entry point address = 0x88000000 INFO: SPSR = 0x3c9 I found a possible solution from the archives: [https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.…]. I try to modify the dts file under edk2-platform/Platform/ARM/VExpressPkg/DeviceTree/ to change the DDR memory range, which is similar to the modification for RME in [https://github.com/ARM-software/arm-trusted-firmware/blob/master/fdts/fvp-b…], but it does not solve the problem. So, how can I boot Linux in the normal world with RME enabled? Thanks,

Addition of write() capability to IO MTD layer

by brian.neely＠analog.com

Hello, A project I’m working on requires write capability for a NOR flash device in BL2 (to update a small boot mux partition). I am considering adding this capability to the IO MTD layer (https://github.com/ARM-software/arm-trusted-firmware/blob/master/drivers/io…), but before doing so wanted to confirm this is in line with the architecture of this subsystem. Can someone confirm if this is an acceptable change? Regards, Brian

Version 1.2.12 of zlib was released

by mikemcternan＠google.com

Hi! It looks like TF-A contains zlib 1.2.11 e.g. https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/lib/zlib/z… zlib.net gives their last release as 1.2.12 (March 27, 2022) with the following changelog: "Fix a deflate bug when using the Z_FIXED strategy that can result in out-of-bound accesses. Fix a deflate bug when the window is full in deflate_stored(). Speed up CRC-32 computations by a factor of 1.5 to 3. Use the hardware CRC-32 instruction on ARMv8 processors. Speed up crc32_combine() with powers of x tables. Add crc32_combine_gen() and crc32_combine_op() for fast combines. Due to the bug fixes, any installations of 1.2.11 should be replaced with 1.2.12." I'm not sure if this is significant as I couldn't find usages of deflate, but thought I would mention it in case others are relying on this functionality and wish to update. Kind regards, Mike

synopsis emcc adma2/3 modes

by gauravverma999＠gmail.com

Hello all, I need to load Bl2 boot image file from emmc interface from 'Synopsys DesignWare Cores Mobile Storage Host Controller'. I can see an existing emmc driver for synopsis controller but it seems to have only support SDMA mode and not ADMA2 and ADMA3 modes. https://github.com/ARM-software/arm-trusted-firmware/blob/master/drivers/sy… Is my understanding correct. Is there a specific reason why ADMA2/3 modes are not supported in existing driver. Any plan to update them soon? I can see adma2/3 mode support available in Linux driver though. https://github.com/torvalds/linux/blob/master/drivers/mmc/host/sdhci-of-dwc…

Measured boot and external TPM modules

by Ramon Fried

Hi, I'm currently working on porting TFA to our upcoming SOC. We plan to support Measured boot using external I2C TPM module. I'm wondering about the implementation of that in BL1. Do you think that I need to write the measurements directly to the I2C module in BL1 ? I'm asking because I would like to have the least source of problems in BL1 which I can't upgrade. I thought of storing the measurements in secure RAM and perhaps copy later. Would love to hear your thoughts. PS. Actually I would love to have the option to choose to implement TPM also in SW (fTPM using optee - as was done in the POC). I think that if I store the measurement of BL2 in secure RAM I can later change the specific TPM while upgrading only BL2/BL31... Thanks, Ramon

[REGRESSION] v2.7-rc0 broken for STM32MP boards: lxa-mc1, avenger96, odyssey

by Ahmad Fatoum

Hello Yann, Hello Pascal, I've tried booting v2.7-rc0 on the lxa-mc1 and TF-A panics: NOTICE: CPU: STM32MP157C?? Rev.B NOTICE: Model: Linux Automation MC-1 board ERROR: regul ldo3: max value 750 is invalid PANIC at PC : 0x2ffeebb7 because the driver takes great offense at the content of the device tree. The parts in question were copy-pasted from ST DTs, but those ST DTs were fixed by commit 67d95409baae ("refactor(stm32mp1-fdts): update regulator description"). I can understand ST hesistancy to touch device trees of 'unofficial' boards, but I would appreciate that new features then, such as this regulator sanity checking, be made optional and off by default to not needlessly break other boards. Thanks, Ahmad -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
