[i.MX53 QSB] Inter-component Shared Memory
by Tiago Brito 09 Jun '16

09 Jun '16

Hi, I have an i.MX53 QSB and have been adapting the tz_vmm example for my needs. As said in previous posts I have a system call which is responsible for the SMC between the normal world and tz_vmm. I can successfully allocate memory in the normal world and access it in the secure world. Thus I can send images to the secure world (which is what I want). Then in the secure world I have a new component which uses the libpng port to process images. TZ_VMM and the libpng component talk using the inter-component RPC. In order to access the image inside the libpng component I send Genode::addr_t in the RPC function call argument. This Genode::addr_t has the physicall address of the image which was loaded to memory from Linux. I can verify that the addr_t variable has the correct value inside the libpng component, but when I try to access it this is the output: [init -> tz_vmm] image addr: 816ac000 [init -> tz_vmm] RPC call: png_sig_cmp [init -> libpng_server] image addr: 816ac000 no RM attachment (faulter 27213c with IP 700101d4 attempts to read from address 816ac000) init -> libpng_server -> ep: unresolved pagefault at ip=700101d4 sp=e01fee30 fault address=816ac000 core -> pager_ep: cannot submit unknown signal context Since this is a memory block which was allocated by Linux, and since I can manipulate it fine when inside tz_vmm, shouldn't I be able to manipulate this same memory region without problems? Thanks a lot! Tiago

Hello! I'm running netperf TCP_STREAM and TCP_MAERTS tests for lxip stack and i obtained extremely low result - 5x10^6 bits/s while the maximum throughput is 1000 mbit/s . I wonder what could be the reason for that. Anna

[TZ_VMM] - libpng on the i.MX53 QSB
by Tiago Brito 03 Jun '16

03 Jun '16

Hi, I've been trying to use libpng inside the secure world of i.MX53 QSB TrustZone aware TZ_VMM example. I want to receive an image from the normal world (running Linux) and do some process the image in some way inside the secure world. I understand the flow of genode and tz_vmm in particular and there are some examples on how to communicate data between the normal and secure world, so that's not my problem right now. My problem is that I cannot run tz_vmm after adding libpng as a lib. In order to use libpng inside tz_vmm I did the following: 1) in $(BUILDDIR)/etc/build.conf uncommented this line REPOSITORIES += $(GENODE_DIR)/repos/libports 2) inside $(GENODE_DIR)/repos/libports I did: make prepare PKG="libc zlib libpng" 3) inside $(BUILDDIR)/repos/os/src/server/tz_vmm/spec/imx53 I added the following to target.inc LIBS += libc LIBS += zlib LIBS += libpng 4) then I added #include <png.h> inside main.cc 5) finally inside $(BUILDDIR) I did make run/tz_vmm All these steps compiled fine, but when I run this on my board the following message comes up: ## Booting kernel from Legacy Image at 70200000 ... Image Name: Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 7888432 Bytes = 7.5 MiB Load Address: 70010000 Entry Point: 70010000 Verifying Checksum ...

Do I need to compile anything else in order to libpng to be usable inside genode? Thanks in advance! Best regards, Tiago

SABRE tablet demo: compilation error on Ubuntu 14.04
by unknown＠example.com 03 Jun '16

03 Jun '16

Hi, I am trying to build the demo https://github.com/skalk/genode/blob/i.MX53_tablet_demo/os/src/server/vmm/i… for the SABRE tablet. In the final step of building the demo: ! make run/vmm I encounter the following errors. I have run "make prepare" in the genode/libports directory, as suggested by https://sourceforge.net/p/genode/mailman/message/32241606/. I am using Ubuntu 14.04. Any idea on how to fix this? Thanks!

[TZ_VMM] - i.MX53 QSB
by Tiago Brito 31 May '16

31 May '16

Hi, I have an i.MX53 QSB development board and I want to experiment with ARM TrustZone. I'm a beginner with regards to genode and kernel development in general. I was able to run tz_vmm on the QSB and interact with the linux which runs in normal world. What I want to do next is a fairly simple system where inside linux I can call an SMC and switch to the secure world, then whilst in secure world print something (like "Hello From Secure World" and also print some argument from the normal world) and then go back to linux. I have read some of the messages in the mailing list and I noticed some of you (other mailing list subscribers) already achieved similar communication protocols but because I'm new to genode I don't know where to start. I know I probably have to create a kernel module for the linux running in normal world so I can call SMC from a userspace application, but I don't know how to do that since I don't see where the linux is being compiled for genode [1]. Do I have to compile another linux? How do I incorporate this new linux version to work with genode? Besides this I also don't know where to start modifying tz_vmm in order to achieve my goals. I know where tz_vmm's code is but I don't know where to start changing it. I have also seen some mailing list questions regarding the world switch from secure world to normal world. It seems that from normal to secure you should call an SMC, but from secure to normal the monitor mode implementation cannot handle entries from the secure world and thus no SMC can be called directly [2]. Can you give my some feedback on how to achieve these things on the i.MX53 QSB? Thanks in advance, Tiago [1] - https://sourceforge.net/p/genode/mailman/message/33244107/ [2] - https://sourceforge.net/p/genode/mailman/message/34244066/

[IPU] - Framebuffer Driver on the i.MX53 QSB
by Tiago Brito 31 May '16

31 May '16

Hi, I want to build a system based on the TZ_VMM example where a user space Linux application can trigger a SMC. This SMC will tell the secure world to display an image (and then return to the normal world after some time or after the user explicitly triggers another world switch). For now I want to start by using Linux on the Normal World, but I want to eventually run Android in the Normal World. The question which made me come to the mailing list is the following: in your article regarding TrustZone [1], section "Additional device drivers", you write that in order to run Android at almost-native performance in the normal world you used hardware overlays and that you invested significant development time into enabling this feature on the QSB. Does this mean you have a working framebuffer driver for the i.MX53 QSB as well as a working example on how to use hardware overlays on this platform? If so I would like to know where can I get the mentioned framebuffer driver as well as the hardware overlay example. Thanks, Tiago [1] - An Exploration of ARM TrustZone Technology ( http://genode.org/documentation/articles/trustzone)

16.05 printf test does not build for Cortex A9.
by Bob Stewart 30 May '16

30 May '16

Hi, It appears that the 16.05 build uses a new environment parameter BASE_HW_DIR, which cause a build on a Cortex A9 based platform to fail in lib/mk (that is, base-hw/lib/mk/spec/cortex_a9.h) bob@...297...:/Work/Genode/Builds/16.05/437x$ make run/printf including /Work/Genode/genode-16.05/tool/run/boot_dir/hw including /Work/Genode/genode-16.05/tool/run/image/uboot including /Work/Genode/genode-16.05/repos/base/run/printf.run building targets: core init test/printf spawn make core init test/printf make[1]: Entering directory `/Work/Genode/Builds/16.05/437x' checking library dependencies... /Work/Genode/genode-16.05/repos/base-hw/lib/mk/spec/cortex_a9/core.inc:25: /lib/mk/spec/smp/core.inc: No such file or directory /Work/Genode/genode-16.05/repos/base-hw/lib/mk/spec/cortex_a9/core.inc:26: /lib/mk/spec/arm_v7/core.inc: No such file or directory make[3]: *** No rule to make target `/lib/mk/spec/arm_v7/core.inc'.

Announcement: Genode OS Framework version 16.05 released
by Christian Helmuth 27 May '16

27 May '16

The central aspect of the current release is the fundamental renovation of our base API. The API gradually evolved over the years since 2006 while we gained a wealth of experience with a wide range of usage scenarios and their requirements. We eventually realized that the need for fundamental changes to greatly increase robustness and flexibility can no longer be ignored. Therefore, this release brings new API functions reflecting our current knowledge about how a secure, low-complexity C++ OS framework should look like and, on the other hand, deprecates a wide range of interfaces that will be removed in future versions. Beside the API changes, we packed quite a few exciting features and improvements into the release. The current release contains the following changes and new features: - Fundamental revision of the framework API - New revision of the "Genode Foundations" book - Enhanced ACPI support on x86 - Device drivers - Updated Linux-based drivers to Linux version 4.4.3 (Intel wireless, Intel graphics, USB, TCP/IP stack) - Updated OpenBSD-based audio driver to version 5.9 - GNU debugger running on 64-bit NOVA - Rust programming language for Genode components - Tool-chain update Find the complete release documentation for the version 16.05 here http://genode.org/documentation/release-notes/16.05 Kind regards -- Christian Helmuth Genode Labs http://www.genode-labs.com/ · http://genode.org/ https://twitter.com/GenodeLabs · /ˈdʒiː.nəʊd/ Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

About GPU support on ARM platforms
by Reinier Millo Sánchez 26 May '16

26 May '16

Hi Genode community I'm working with Exynos4 and RPi, both ARM platforms. I'm interested to use the GPU on both platforms to enconde/decode video. Is somebody working on ARM GPU drivers, or have worked on it? I'm using basically FiascoOC as microkernel, but if i use Linux as base kernel, how i can use the linux device driver through GenodeOS? So that the applications developed have a minimum kernel dependencies, allowing later the replacement of the linux kernel by FiascoOC microkernel, when the device driver is implemented.
