base-hw running on a Cortex A7 processor?
by Robert Stewart 09 Mar '23

09 Mar '23

I'm about to start to bring up a base-hw implementation on an Arm Cortex A-7 quad core Allwinner H3 board. Has this already been done by anyone? The A7 is "similar" to the A9 with the addition of LPAE. As opposed to the A9, it has GIC v2 and an SCU with an L2 Cache tightly coupled to it, mean that you can turn on or off the cache and that's all the control you have. It looks like the Cortex A15 implementation already in base-hw would be a good model to follow to get the A7 running. Bob Stewart Get Outlook for Android<https://aka.ms/AAb9ysg>

Sculpt 22.10 not working on Thinkpad X201
by dogma＠disroot.org 06 Mar '23

Image dd'ed to a flash drive, and I checked that vt-d, vt-x, and NX were as they should be. GRUB shows the splash image briefly, the screen goes blank black, something in the computer makes a moderately high-pitched sound for five seconds or so, and nothing more happens.

Porting OpenJDK in Genode.
by YamiNI ReddY 06 Mar '23

06 Mar '23

Dear Genodians, I am writing to you to request your guidance on porting OpenJDK to run simple java programs in Genode. As I have been looking into the possibilities of running OpenJDK on Genode. I have been searching for documentation and resources on the subject, but I have not been able to find any comprehensive guide that explains the process in detail. Could you please guide me on the steps involved in porting OpenJDK to Genode? Additionally, if you know of any resources or documentation that could be useful for me, I would be grateful if you could share them with me. Thank you very much for your time and consideration. Best regards, Yamini

Trustzone with virt_qemu_arm_v8a
by Devashish Dewangan cs21m017 02 Mar '23

02 Mar '23

Dear Genodians, I am working with virt_qemu_arm_v8a, and I read the extensive documentation on how Genode has experimented with the Trustzone of ARM. I want to explore the Trustzone and run an application in the secure mode, but I wanted to know if it is possible to do with virt_qemu_arm. -- Regards, Devashish Dewangan CS21M017

jitterentropy base genode nstime.h for virt riscv
by Pranab Kumar Rout cs21m045 01 Mar '23

01 Mar '23

Hello all, While building sculpt for virt riscv, I was getting undefined reference errors in app/gpt_write, Based on Norman's suggestions earlier, I updated the recipe for the jitterentopy API [1] that is used to assemble the content in depot/genodelabs/api/jitterentropy/<version>/ [1] genode/repos/libports/recipes/api/jitterentropy/content.mk This helped me overcome the undefined reference errors, But now I am getting: Library jitterentropy COMPILE jitterentropy-base-genode.o COMPILE jitterentropy-base.o genode/depot/genodelabs/api/jitterentropy/2023-02-24/src/lib/jitterentropy/spec/riscv/jitterentropy-base-genode-nstime.h: Assembler messages: genode/depot/genodelabs/api/jitterentropy/2023-02-24/src/lib/jitterentropy/spec/riscv/jitterentropy-base-genode-nstime.h:20: Error: unrecognized opcode `mrc p15,0,a5,c9,c13,0' make[7]: *** [genode/repos/base/mk/generic.mk:58: jitterentropy-base.o] Error 1 make[6]: *** [var/libdeps:112: jitterentropy.lib] Error 2 make[5]: *** [Makefile:336: gen_deps_and_build_targets] Error 2 This error seems be due the contents of the header file (That I had created): repos/libports/src/lib/jitterentropy/spec/riscv/jitterentropy-base-genode-nstime.h because jitterentropy was not enabled yet on riscv, I had to create this file myself. Contents of [2] that I had written: #ifndef _JITTERENTROPY_RISCV_BASE_GENODE_NSTIME_H_ #define _JITTERENTROPY_RISCV_BASE_GENODE_NSTIME_H_ static inline void jent_get_nstime(__u64 *out) { uint32_t t; asm volatile("mrc p15, 0, %0, c9, c13, 0" : "=r"(t)); *out = t; } #endif [2] *repos/libports/src/lib/**jitterentropy/spec/riscv/* jitterentropy-base-genode*-**nstime.h * I tried to build it by looking at the header files corresponding to other architectures. I am not aware of opcode for riscv. Please guide me to write the correct code. what should be written in this header file for riscv. Thanks and regards, Pranab Kumar Rout
