Physical memory allocation.
by Daniel Waddington 18 Mar '13

18 Mar '13

Hi, For the purpose of NUMA based memory management, I would like to have Genode allow me to allocate physical memory at a specified address, i.e., support something like... |||||||||virtual| ||Ram_dataspace_capability ||alloc||_at(|||size_t ||size|||, addr_t start_address, |||bool ||cached|| |=| true|)||| ||=| 0|; I figure I can temporarily hack this by extending Ram_session_component::alloc and using Range_allocator::alloc_addr. Is there any danger here? Can Genode be persuaded to extend the main line to support this? An address range parameter instead of start address would be even better, i.e., try to allocate me some RAM somewhere between physical address X and Y. Best, Daniel |||||||

hi i want to get the l4linux running.i followed the step according to source tree file --genode/base-foc/doc/foc.txt.i did make prepare in 'ports-foc' and 'dde_ipxe' repository in genode source tree. i edited the 'etc/build.conf' file in my build directory,and uncomment the following line : REPOSITORIES += $(GENODE_DIR)/dde_ipxe REPOSITORIES += $(GENODE_DIR)/ports-foc i downloaded the 'inird.gz' file and resided it in 'bin' in my build directory. i thought i did everything well, but when i make run/l4linx ,there comes a issue,here is the message: using run script /home/wangyuqing/下载/genode/base-foc/run/env using run script /home/wangyuqing/下载/genode/ports-foc/run/l4linux.run building targets: core init drivers/timer drivers/uart drivers/framebuffer l4linux drivers/nic drivers/pci drivers/input/ps2 spawn make core init drivers/timer drivers/uart drivers/framebuffer l4linux drivers/nic drivers/pci drivers/input/ps2 make[1]: 正在进入目录 `/home/wangyuqing/下载/genode_focx86_builddir' checking library dependencies...

Hi I am new in Genode.I downloaded genode and genodetoolchain fromhttp://genode.org/download<http://genode.org/download/tool-chain>. After I followed the step according to http://genode.org/documentation/developer-resources/getting_started , I was getting a issue. I followed the step to build genode for linux.After make run/demo,these message was shown: spawn ./core int main(): --- create local services --- int main(): --- start init --- int main(): transferred 4095 MB to init int main(): --- init created, waiting for exit condition --- [init] Could not open file "ld.lib.so" [init -> launchpad] Could not open file "ld.lib.so" [init -> launchpad] Could not open file "config" [init -> launchpad] Could not obtain config file [init -> timer] args='label="nitpicker", ram_quota=4096' [init -> fb_sdl] creating virtual framebuffer for mode 1024x768@...64...

Announcement: Genode OS Framework version 13.02 released
by Norman Feske 28 Feb '13

28 Feb '13

I am delighted to announce the release of Genode version 13.02. The overall theme of this version is improving the framework's platform support. This is most prominently visible in the form of the many NOVA-specific improvements and the addition of the Cortex-A15-based Exynos 5250 SoC. But those are only a small part of the whole story, which is described in full detail in the release notes: http://genode.org/documentation/release-notes/13.02 The release-notes summary follows: - DMA protection via IOMMU (NOVA/x86) - Full virtualization via the Vancouver VMM (NOVA/x86) - Redesigned audio-output support for low latency - Base API and OS infrastructure - New fault-detection facility - New mechanism for file-system notifications - New terminal multiplexer - Device drivers - ACPI support for 64-bit machines - New OMAP4 UART driver - USB support for Samsung Exynos 5250 - Base platforms - Custom kernel platform with added support for Samsung Exynos 5250 and Freescale i.MX53 - NOVA kernel improved for highly dynamic workloads - Fiasco.OC kernel forked, Exynos-5250 support added - Improved memory management on Linux I wish you a lot of fun with exploring the new version!

On memory mapping
by Dmitry Shubin 28 Feb '13

28 Feb '13

Hello. I want to map a single memory page twice to two different virtual addresses with different attributes within a single address space. In particular (for testing purposes) I want to have a piece of memory that is accessible as cacheable and non-cacheable region at different addresses. How can I make this happen? Is this even possible with existing API?

Native_capability as [out] parameters
by Daniel Waddington 25 Feb '13

25 Feb '13

Hi, Can I pass Native_capability types as [out] parameters using "Native_capability *" type - with the cross-process mapping happening? Most of the examples use only use the return value to do [out] capabilities. i.e. GENODE_RPC(Rpc_foo,int,foo,Genode::Native_capability *) doesn't seem to work, but there might be something else afoot.

Update base-foc to use rev. 47
by Dmitry Shubin 20 Feb '13

20 Feb '13

Hello. I've updated Makefile and a patchset to use the latest snapshot of Fiasco.OC. So far I've tested only foc_x86_32 and foc_x86_64 under qemu, but we should be able to test foc_panda and foc_imx53 builds as well soon. The patch is available here on foc-r47 branch: git://github.com/Ksys-labs/genode.git

What is going on for february release?
by Paul Dufresne 20 Feb '13

20 Feb '13

Well, february 2013 is at our door now, and I would like to remember us of the plan for it according to our 2013 roadmap: -Low-latency audio support The current audio_out-session interface was our first shot into the direction of audio processing. To enable use cases where streaming audio and sporadic sounds must be accommodated at the same time, we need to revise our approach. -IOMMU support on NOVA -First steps of user-interface concept --UI concept for pleasant working environment --Tiled window manager --Terminal improvements (e.g., scroll buffer) --Noux improvements (e.g., signals) -Improved x86 virtualization support --Improved virtualization support (Vancouver on NOVA) I'd like to have a small picture of who is working on what in the previous list. And the current status of things.

[Genode] who writes data into Thread_base::Context::stack?
by jaeyong yoo 19 Feb '13

19 Feb '13

Hello Genode, I was trying to find what kind of data has been written into Thread_base::Context::stack, but I couldn't. Could you tell me which part of the source code writes data into "Thread_base::Context::stack?" Best regards, Jaeyong
