CSU in IMX53
by Franc sylvester 12 Dec '14

12 Dec '14

Hi, I am not able to collect the particular bit information of peripheral devices connected in imx53 SoC from the imx53 reference manual. Can Any one suggest me some sources which have information used in repos/base-hw/src/core/include/spec/imx53/trustzone/csu.h Regards frank

set access permission for service object
by li94575 10 Dec '14

10 Dec '14

Hi, all Genode gives all the access permission for the object when it does capability mapping（I use fiasco.oc as the base platform）, like this: Capability_map::insert_map(int id, addr_t kcap) { ..... /* map the given cap to our registry entry */ l4_task_map(L4_BASE_TASK_CAP, L4_BASE_TASK_CAP, l4_obj_fpage(kcap, 0, L4_FPAGE_RWX), i->kcap() | L4_ITEM_MAP | L4_MAP_ITEM_GRANT); ..... } If I only give the reading permission for the object, How to perform permission checking on server side?

Starting TZ_VMM on imx6
by Swaminathan Ramesh 10 Dec '14

10 Dec '14

Hello all, I am currently working on TZ_VMM on the imx6 platform. Though the majority of the code is extremely similar to the imx53 port that is already present, there is a problem that arises due to the TrustZone Protection Controller for imx6. The address for the TZPC for imx6 is different from the TZPC of imx53 and the Versatile Express ports that already exist in Genode, so these addresses do not work when I used them. The TZPC base address for imx6 is not provided in the Freescale documentation or on the ARM infocenter. I was wondering if you guys can give me any ideas on how to go about solving this issue. Thanks, -- Best regards, Swaminathan Ramesh

Genode isn't finding IDE Drive
by Nobody III 07 Dec '14

07 Dec '14

My computer has a SATA hard drive which is only accessible through the IDE interface (so AHCI doesn't work). Unfortunately, Genode doesn't detect it. I mentioned this problem earlier, but now I have a null modem cable to get the debugging info. Here is the full serial output: Welcome to Fiasco(ia32)!

iwlwifi for 7260 card: DMA memory allocation fails
by Christian Menard 05 Dec '14

05 Dec '14

Hi everyone, First of all thanks for the great work on the new release, keep it up! I'm experimenting with the new iwlwifi driver on a device with 7260 card. I enabled support for this card as mentioned in the release notes and added the corresponding firmware file iwlwifi-7260-8.ucode. Unfortunately the driver is not working out of the box for this card. The problem breaks down to a failure during DMA memory allocation. Here an excerpt from wifi_drv's log: > Slab too large 131072 reqested 86032 cached 0 > dma alloc 81920 failed > Slab too large 131072 reqested 105428 cached 0 > dma alloc 101316 failed > .... > Slab too large 131072 reqested 86032 cached 0 > dma alloc 81920 failed > Slab too large 262144 reqested 175072 cached 0 > dma alloc 170960 failed I naively increased maximum slab size by setting SLAB_STOP_LOG2 in lxc_emul.cc to 20. Then failure changes to: > Failed to get slab for 262144 > dma alloc: 170960 failed So as it appears such a large slab cannot be allocated. Why is that? What would be the right way (tm) to resolve this issue? Thanks Christian

Dynamic Memory Management
by Nobody III 01 Dec '14

01 Dec '14

As far as I can tell, init will only allocate fixed amounts of memory to each process. Is there a way to allow each process as much memory as it needs up to a certain limit (e.g. 1G) without reserving excess memory for each process?

USB Wifi
by Nobody III 01 Dec '14

01 Dec '14

May I put in a request for USB wireless support? I know that it may take a lot of effort, but I would really like support for my USB Ralink RT2870/RT3070 wireless adapter. With wireless support and better IDE support, I will be well-equipped to begin porting software to genode.

Create VESA Modes
by Nobody III 29 Nov '14

29 Nov '14

Based on the readme for the VESA driver, my HD monitor won't work at full resolution in Genode. I had this same problem with Windows XP, which I was able to solve with DTDCalculator, a tool which let me create custom video modes. Since 1920x1080 was blacklisted (or something like that), I set the screen resolution to 1920x1081. Could functionality like this be added to Genode?
