Hello, I want a thread to exit after it finishes its job. The function pthread_exit seems not working. I still can see all threads I created through kernel debugger. Any idea? Best, Chen

Nokia N900 and Fiasco.OC/l4re
by Valery V. Sedletski 29 Jun '11

29 Jun '11

Hi all Is there a possibility to use Fiasco.OC and L4Re with L4Linux on Nokia N900 internet tablet/phone? Which ARM platform it is compatible with, if so? -- It is based on ARM Cortex A8 600 MHz processor, 256 Mb RAM and 784 Mb swap, Maemo (Debian GNU/Linux based) platform (see http://www.gsmarena.com/nokia_n900-2917.php, for example). Or, if not so, is it possible to use it with Genode or OKL4? WBR, valery

crash: l4linux with virtual PCI bus enabled

Hi list, (please CC me, as I'm not subscribed) I was trying to run l4linux supposed to boot from a NFS root file system. I enabled PCI support and the virtual PCI bus. I was successfully able to establish a network connection to my NFS server, however shortly after I get: l4linux | Page fault (non-resolved): pfa=6 pc=61fff9 Die message: Trap: 14 Trap: 14: 0006 [#1] ... Kernel panic - not syncing: Fatal exception in interrupt I am mostly running a setup with the supplied example configurations. This is my setup: * l4re: http://svn.tudos.org/repos/oc/tudos r33 * l4linux: http://svn.tudos.org/repos/oc/l4linux/trunk, r19 * run time environment: Debian Squeeze x86, gcc version 4.4.5, qemu (0.12.5) * I'm starting l4re with: "qemu -m 768 -vnc :1 -cdrom images/l4linux-mag-x86.iso -serial stdio -net nic,model=e1000 -net user" where l4linux-mag-x86.iso was generated by: * "make grub2iso E=L4Linux-mag-x86 MODULES_LIST=~/ssl/modules.list MODULE_SEARCH_PATH=~/kernel-build/:~/l4linux/:~/bootstrap/" Moreover (hopefully) I attached all configuration files below. all remaining files are untouched from the example configurations.

Properly detect muliple PCI root brings in L4Re's io process
by Christian Ehrhardt 16 Jun '11

16 Jun '11

Hi, I tried to run fiasco and L4Linux on an SMP machine that features two idenpendent PCI root bridges. Currently, the io process fails to scan the bus connected to the second bridge. It properly detects that two PCI root bridges are present and creates two seperate Pci_port_root_bridge objects. However, it fails to initialize the Pci_bridge::num field properly. As a result, the io process scans the first bus twice. This causes major havoc as PCI devices on the second bus don't show up in L4Linux at all and devices on the first bus are detected twice. According to http://www.acpi.info/acpi_faq.htm the ACPI structures should contain a _BBN method to detect the bus number of both root busses. The following patch uses this method to detect and set the Pci_bridge::num field properly. A patch to fix this is provided below. With this patch NICs on both PCI busses are detected and work properly on the hardware in question. As always comments are appreciated. regards Christian The contributions made by this patch are licensed under the MIT license (http://www.opensource.org/licenses/mit-license.php) diff --git a/src/l4/pkg/io/server/src/acpi.cc b/src/l4/pkg/io/server/src/acpi.cc index f76c768..4179c4e 100644 --- a/src/l4/pkg/io/server/src/acpi.cc +++ b/src/l4/pkg/io/server/src/acpi.cc @@ -572,9 +572,25 @@ discover_pre_cb(ACPI_HANDLE obj, UINT32 nl, void *ctxt, void **) //AcpiUtReleaseMutex(ACPI_MTX_NAMESPACE); // hm, this seems very specific for PCI + /* + * Systems with multiple PCI root bridges must provide the PCI bus + * number of each bus via the _BBN method. + */ if (pci_rb) { - d_printf(DBG_DEBUG, "Found PCI root bridge...\n"); + ACPI_INTEGER pci_int; + bool have_bbn = false; + + if (ACPI_SUCCESS(AcpiUtEvaluateNumericObject((char*)METHOD_NAME__BBN, + node, &pci_int))) + { + d_printf(DBG_DEBUG, "PCI root bridge with BBN=%llx...\n", pci_int); + have_bbn = true; + } + else + { + d_printf(DBG_DEBUG, "Found PCI root bridge without BBN...\n"); + } if (Pci_root_bridge *rb = pci_root_bridge(0)) { if (rb->host()) @@ -582,9 +598,13 @@ discover_pre_cb(ACPI_HANDLE obj, UINT32 nl, void *ctxt, void **) // we found a second root bridge // create a new root pridge instance rb = new Pci_port_root_bridge(nd); + if (!have_bbn) + d_printf(DBG_ERR, "ERROR: Multiple root bridges without BBN\n"); } else rb->set_host(nd); + if (have_bbn) + rb->num = pci_int; nd->set_discover_bus_if(rb); }

Pager in Fiasco.OC

Hello, In Fiasco.OC, can we register a distinct pager for each thread? I wonder if l4_thread_control_pager is for this purpose. Thanks, Chen
