Help testing arora,qt5 and sdl examples on RaspberryPI
by Reinier Millo Sánchez 09 Sep '14

09 Sep '14

Hi I'm testing some examples of Genode on RaspberryPI, but i got some troubles. I'm trying to test arora, qt5 and sdl examples. I'm using Genode 14.05. I have configured the following ports: ./tool/ports/prepare_port arora ./tool/ports/prepare_port dde-linux ./tool/ports/prepare_port libc ./tool/ports/prepare_port stdcxx ./tool/ports/prepare_port mesa ./tool/ports/prepare_port zlib ./tool/ports/prepare_port icu ./tool/ports/prepare_port jpeg ./tool/ports/prepare_port libpng ./tool/ports/prepare_port openssl ./tool/ports/prepare_port freetype ./tool/ports/prepare_port lwip ./tool/ports/prepare_port qoost ./tool/ports/prepare_port bintuils ./tool/ports/prepare_port sdl make prepare PKG=qt5 (on libports) On etc/build.conf have activated the following repositories: REPOSITORIES += $(GENODE_DIR)/repos/base-hw REPOSITORIES += $(GENODE_DIR)/repos/base REPOSITORIES += $(GENODE_DIR)/repos/os REPOSITORIES += $(GENODE_DIR)/repos/demo REPOSITORIES += $(GENODE_DIR)/repos/libports REPOSITORIES += $(GENODE_DIR)/repos/ports REPOSITORIES += $(GENODE_DIR)/repos/dde_linux REPOSITORIES += $(GENODE_DIR)/repos/gems To compile the example have used the following command lines: make run/arora make run/qt5 make run/sdl During the compilation process of the examples, get this line, but finally the elf image is generated: /usr/local/genode-gcc/bin/genode-arm-ld: BFD (GNU Binutils) 2.22 assertion fail ../../../../contrib/binutils-2.22/bfd/elf32-arm.c:12049 To generate the img file from the elf image have used: /usr/local/genode-gcc/bin/genode-arm-objcopy -Obinary var/run/arora/image.elf genode_arora.img /usr/local/genode-gcc/bin/genode-arm-objcopy -Obinary var/run/qt5/image.elf genode_qt5.img /usr/local/genode-gcc/bin/genode-arm-objcopy -Obinary var/run/sdl/image.elf genode_sdl.img To test this img on the RPI have created the config.txt file with: kernel=<file>.img kernel_address=0x00800000 To test the examples i'm using a RPI model B and a version of QEMU with functional support for RPI: https://github.com/Torlus/qemu/ When test the elf images with QEMU get the output on serial console, but this version of QEMU seems like don't support framebuffer emulation. After that have tried to run examples on the real PI but only get the coloured screen. I have compiled and tested on th RPI the Demo and Hello examples. If somebody can help me? Best regards -- Lic.

TrustZone on imx6
by chirag garg 09 Sep '14

09 Sep '14

Hi all, As Genode is successfully running on imx6 board. Now , I want to enable the TrustZone on imx6 processor. As i read on Page http://www.genode.org/documentation/articles/trustzone I have to build TrustZone aware Hypervisor. For that i have to start Monitor Mode and nitialize a corresponding exception vector that is used when a monitor-mode exception is raised. Is it right direction to begin and help me where should i start looking in imx53 code as a reference code to do this. Regards Chirag Garg IIT Madras , Rise Lab

The added mechanisms in VSOS.
by 王硕 09 Sep '14

09 Sep '14

Hello Norman, Our team developed some apps to present BLP and Biba access-control model. All of these apps can be started in qt_launchpad. In order to simulate a login process, they used several "Connections" (just like Monitor__Connection) to "jump" from the login windows to qt_launchpad (or reversely). Secure attention key was also implemented like this in void handle_event() in ps2_keyboard.h. (https://github.com/kloisiie/vsos/blob/ff16f26ffe37a70fded8d02277e67a0c29e6e…) For example, in main.cpp in qt_launchpad: int main(int argc, char *argv[]) { ... ... ‍ Timer::Connection loginwait; while(true){ if(loginfinished) break; else { loginwait.msleep(1500); } } ... ... ... launchpad->show(); ... ... ... }‍‍ the while(true) loop will be broken if and only if the login app (in qt4/src/apps/verify) validate the username and password and change the loginfinished‍ flag to TURE. Then the login windows hides and qt_launchpad will continue executing and show the window. The default username (the left textbox/QLineEdit in the first line of login app) and passwords (the textbox in the second line) are admin and helloos5, and the default login level (following BLP model, the right ComboBox in the first line) is 2. The audit and access-control mechanism was implemented in /base/include/monitor_session. https://github.com/kloisiie/vsos/tree/master/base/include/monitor_session‍ https://github.com/kloisiie/vsos/blob/master/base/src/core/include/monitor_… Shuo Wang, University of Chinese Academy of Sciences. ------------------ Original ------------------ <kloisiie@...236...>; "genode-main"<genode-main(a)lists.sourceforge.net>; Fw：Re: Some questions about performance optimization related toGUIframework on Genode Hello Norman, Here is a .iso file of the VSOS system.

Translation Table Memory Attribute bits
by Bob Stewart 08 Sep '14

08 Sep '14

I've never been able to get 14.05 or 14.08 working on my AM335X processor, which is not a big deal as 14.02 has everything I need for the applications I'm using that processor for. But out of curiosity: The issue on 14.08 may revolve around memory access bit rights in TLB table entries. To get 14.08 to initialize the kernel properly the memory access bits have to be set as Tex = 0, B = 1, and C = 0. These setting seem correct for a shared Device according to the Arm v7 ref manual. With those settings in place, the kernel initializes properly and eventually init runs. During the kernel initialization process Core_pd is called and translations are created for the program image (which starts at 0x81000000) and the core-only io memory regions. The translation table entries for the program image are of section size plus a small page so two entries are inserted in the translation table. The access bits and permission bits for the section entry are correct with the possible exception of the C bit, which in 14.08 appears never to be set and I wondered why that was, when it is used in 14.02. Once the init thread runs, any reference to the translation table entry for the program image, the section entry mentioned above cause a mmu exception as the following partial debug output shows: ... start thread 3 'entrypoint' in program 1 'core' on processor 0/1 start thread 4 'signal' in program 1 'core' on processor 0/1 start thread 5 'pager_activation' in program 1 'core' on processor 0/1 int main(): --- start init --- int main(): transferred 507 MB to init start thread 6 'init' in program 1 'core' on processor 0/1 thread id is 0x7 start thread 7 'init' in program 2 'init' on processor 0/1 void Kernel::Thread::_mmu_exception(): f_addr 0x81000000 f_writes 0x0 f_pd 0x813ed088 f_signal 0x7f label init int main(): --- init created, waiting for exit condition --- void Kernel::Thread::_mmu_exception(): f_addr 0x81045f60 f_writes 0x1 f_pd 0x813ed088 f_signal 0x7f label init void Kernel::Thread::_mmu_exception(): f_addr 0x8102dab8 f_writes 0x0 f_pd 0x813ed088 f_signal 0x7f label init ... Setting the C bit as it was set in 14.02 makes no difference, which I thought it would and it should be affecting caching behavior. Any thoughts on this behavoir? Thanks, Bob

Malloc / free ansd rump_fs ->Slab-backend exhausted
by unknown＠example.com 05 Sep '14

05 Sep '14

Hi, i try to open a file. I used the following code: //malloc char * buffer = (char*) Genode::env()->heap()->alloc(sizeof(char)*lSize); FILE* pFile = fopen(fileName, "rb"); size_t result = fread (buffer,1,lSize,pFile); fclose (pFile); //free (buffer); env()->heap()->free(buffer, 0); The code seems to work if the file is quite small. I try thre same with a file of size 128 MB. I have given rump_fs a quite large quota of 520M [Quota exceeded! amount=69632, size=8192, consumed=65536[0m [Could not allocate metadata[0m [init -> rump_fs] [upgrading quota donation for Env::RAM (8192 bytes)[0m [Quota exceeded! amount=77824, size=8192, consumed=73728[0m [Could not allocate metadata[0m [init -> rump_fs] [upgrading quota donation for Env::RAM (8192 bytes)[0m [init -> rump_fs] [Slab-backend exhausted! And from this point onwards only Slab-backend exhausted messages are shown. Is there some max size for ram quotas? Best regards, Wolfgang
