Drivers like SD-Card, platform, AHCI, and framebuffer are specified as Exynos5
compliant. But they are at least not compliant with Odroid-XU although this is
Exynos5. Thus, prevent tests that rely on such drivers when building for
hw_odoid_xu. Furthermore, make previous Arndale regulator/consts.h,
uart_defs.h, and some Board_base enums available to all Exynos5 builds to
enable at least building the drivers.
Fixes#1419
With the new run tool, there is no more is_qemu_available function. However,
some scripts still try to use it because only frequently used scripts were
updated by now. The commit replaces the function calls with the new
'have_include power_on/qemu' check.
Ref #1419
Up to now Noux used the libc sleep functions, which actually is not
possible because the _nanosleep() function implemented by our libc
creates a new thread to handle the timeout. Noux childs may have
only one thread, e.g., the main thread, though. To fix this issue
sleeping is now handled directly by Noux. It is implemented by calling
select(2) with a timeout. This fix is needed for mutt(1), which calls
sleep when it prints a notification for the user.
Fixes#1374.
Instead of returning an uint64_t value, return a structured time stamp.
This change is only visible to components using Rtc_session directly.
Fixes#1381.
Be less verbose regards warnings caused by vmx_invalid exits - which triggers
on T400 more often because it has no Unrestricted Guest support. This leads
to lot of log messages so that the test does not succeed in time. Additionally,
the virtualbox_auto_disk.run script is adjusted to check for some output to
exit earlier if something went wrong.
Fixes#1367
In the init configuration one can configure the donation of CPU time via
'resource' tags that have the attribute 'name' set to "CPU" and the
attribute 'quantum' set to the percentage of CPU quota that init shall
donate. The pattern is the same as when donating RAM quota.
! <start name="test">
! <resource name="CPU" quantum="75"/>
! </start>
This would cause init to try donating 75% of its CPU quota to the child
"test". Init and core do not preserve CPU quota for their own
requirements by default as it is done with RAM quota.
The CPU quota that a process owns can be applied through the thread
constructor. The constructor has been enhanced by an argument that
indicates the percentage of the programs CPU quota that shall be granted
to the new thread. So 'Thread(33, "test")' would cause the backing CPU
session to try to grant 33% of the programs CPU quota to the thread
"test". By now, the CPU quota of a thread can't be altered after
construction. Constructing a thread with CPU quota 0 doesn't mean the
thread gets never scheduled but that the thread has no guaranty to receive
CPU time. Such threads have to live with excess CPU time.
Threads that already existed in the official repositories of Genode were
adapted in the way that they receive a quota of 0.
This commit also provides a run test 'cpu_quota' in base-hw (the only
kernel that applies the CPU-quota scheme currently). The test basically
runs three threads with different physical CPU quota. The threads simply
count for 30 seconds each and the test then checks wether the counter
values relate to the CPU-quota distribution.

When the 'Mtd::FPU' flag is set during the registration of a
virtualization event handler, it must also be set whenever the event
handler returns.
Fixes#1283
This is just a quick fix to calm down the buildbot - a revised
implementation is needed according to issue #1277. Further, the reason
for the increased test duration on several platforms must be
investigated.
* use seoul branch containing vbios emulator
* report the memory model in the VBE mode info as otherwise the
Genode framebuffer driver will ignore this mode
Fixes#1261
The port was succesfully tested a echo test and lighttpd. DHCP over
OpenVPN is not tested and probably will not work out of the box.
Therefore, the ip address etc. need to be specified manually.
For now, only ethernet bridging (using a TAP device) is supported.
Fixes#1235.
The console included nitpicker_view headers, which were not used. The
headers vanished with the recent nitpicker API change, which broke the
build of seoul.
This patch enables the debugging on services that rely on dynamic
session upgrades. For example, nitpicker expects its clients to donate
RAM quota that matches the size of the virtual framebuffer, which might
change during the lifetime of a nitpicker session.
* repos/ports/include/vmm
- add support to specify cpu location during vCPU construction
* seoul
- update to latest seoul branch supporting smp
- adjust to vmm interface changes
- vCPUs will be put in a round robin fashion on the available host CPUs,
beginning with the next CPU after the default (boot) CPU
- number of vCPUs can be specified in run script
* virtualbox
- adjust to vmm interface changes
- uses still one vCPU, placed on default (boot) CPU
Fixes#1212
When a page fault cannot be resolved, the GDB monitor can get a hint about
which thread faulted by evaluating the thread state object returned by
'Cpu_session::state()'. Unfortunately, with the current implementation,
the signal which informs GDB monitor about the page fault is sent before
the thread state object of the faulted thread has been updated, so it
can happen that the faulted thread cannot be determined immediately
after receiving the signal.
With this commit, the thread state gets updated before the signal is sent.
At least on base-nova it can also happen that the thread state is not
accessible yet after receiving the page fault notification. For this
reason, GDB monitor needs to retry its query until the state is
accessible.
Fixes#1206.
The count value can be used to batch timeouts. I.e., if a periodic
timeout triggered multiple times before the timer had a chance to
process them, the count corresponds to the number of passed periods.
and add xml configuration option to switch it on if required. Avoids trouble
on Windows 7 guest where IRQ injected by VMMDev PCI device is not delivered.
If ioapic is required and Windows guest addition "hangs", look in file
DevPCI.cpp, function pciSetIrqInternal, variable fIsApicEnabled. If
config[0xde] == 0xbe
config[0xad] == 0xef
it works. "Deadbeaf" seems to/should be set in ACPI file vbox.dsl. Happens for
unknown reason not on Genode/Nova.
Fixes#1188
On ARM it's relevant to not only distinguish between ordinary cached memory
and write-combined one, but also having non-cached memory too. To insert the
appropriated page table entries e.g.: in the base-hw kernel, we need to preserve
the information about the kind of memory from allocation until the pager
resolves a page fault. Therefore, this commit introduces a new Cache_attribute
type, and replaces the write_combined boolean with the new type where necessary.
In file
src/VBox/Additions/WINNT/SharedFolders/driver/file.c
the function
static int vbsfTransferCommon(VBSFTRANSFERCTX *pCtx)
in the
VbglR0CanUsePhysPageList()
branch does not correctly evaluate the read or written bytes from
the VMM. It ever assumes that whole pages are read/written.
Workaround the bug in the Windows guest additions of Vbox until fixed
upstream by filling up the read/write buffer completely within the VMM code
of Vbox.
