* The Vm thread is always paused and on exception to make sure that guest VM
execution is suspended whenever we handle an interrupt. Also signal the Vm
session to poke waiting threads (e.g. Virtualbox EMT).
* Implement Vm::proceed
Switch to the mode transition assembly code declared at the _vt_vm_entry
label.
Issue #2016
The entry enables interrupts and initiates a handover to the guest VM by
invoking event number one. The sti instruction is placed at the start to
allow exits to Muen before handing off to the VM if window exiting is
requested.
Issue #2016
The virtual PCI model delivers IRQs to the PIC by default and to the
IOAPIC only if the guest operating system selected the IOAPIC with the
'_PIC' ACPI method and if it called the '_PRT' ACPI method afterwards.
When running a guest operating system which uses the IOAPIC, but does
not call these ACPI methods (for example Genode/NOVA), the new
configuration option
<config force_ioapic="yes">
enforces the delivery of PCI IRQs to the IOAPIC.
Fixes#2029
The alternate stack must use the stack area as, e.g., Thread::myself()
depends on this property. Hybrid components do not depend on this
property and, therefore, use a static stack buffer.
Fixes#1935
* Align pitch value to 64 byte (thanks to cnuke for investigation)
* Get rid of extra dataspace retrival and attachment, now that we always buffer
* Consistently name all lx_emul helpers: lx_* (get rid of dde*)
* Add missing file headers
Fix#1997
Instead of providing a buffer to the client and blitting from that
to the "real" framebuffer as an option, with this commit we always do so.
Thereby its possible to immediately destroy the old framebuffer used by
hardware when a configuration change is done, and a new framebuffer
is used. This also simplifies the modesetting.
Moreover, this commit fixes an issue when not using the connector reporting.
Until now the initial mode detection of connectors was only done when
the report was created. this is a regression that entered the driver
when upgrading to the recent Linux kernel version.
Ref #1997
Use new env, component and logging frameworks.
Sync file system and block device on component entrypoint.
Support for 'root' session argument.
Increase Rump open file descriptor limit.
Issue #1987Fixes#2011
* remove all 'Genode::env()' calls
* use attached roms to read configuration
* use compoenent framework
* remove all PDBG, PINF, PWRN macros
Issue #1987Fixes#2019
* use Component::* instead of Server::*
* do not use old printf format anymore
* do not use old Genode::env()->heap() anymore
* avoid pointers where possible, and use references instead
* throw away the thread-safe variants of list and AVL tree,
nic_bridge became single-threaded in the past
* introduce Ram_session_guard instead of Allocator_guard
Issue #1987
- platform_drv announces a separate "Acpi" session
- platform_drv waits for ROM "system" to change state to "acpi_ready"
- acpica waits for "Acpi" announcement
- acpica uses the platform driver via "Acpi" to reconfigure PCI devices
- acpica changes "system" state to "acpi_ready" after it ready with initialization
- platform_drv reacts on "system" state change to "acpi_ready" by announcing "Platform" session
- drivers start to operate as usual
Issue #2009
This patch introduces the Genode::raw function that prints output
directly via a low-level kernel mechanism, if available.
On base-linux, it replaces the former 'raw_write_str' function.
On base-hw, it replaces the former kernel/log.h interface.
Fixes#2012
This is a follow-up commit to "slab: throw exception if initial
allocation fails". It is needed because on seL4, the PD session quota is
used as backing store for the meta data of the PD's virtual memory. For
this reason, PD sessions on seL4 require more session quota compared to
the other kernels. Apparently, the default quota is too scarce to
complete the PD-session construction. By shrinking the number of
supported page-table entries, we reduce the size of the PD session
component so that the creation succeeds.
Issue #1983
Replace 'attribute(...).has_value("yes")`
with 'attribute_value(..., false)'.
This allows for boolean configuration to be set with values such as
"true", "false", "yes", "no", or "1", "0".
Fixes#2002
A configuration policy must match against a policy node label,
label_prefix, or label_suffix atttribute. A fallback to
<default-policy/> is provided as a label wildcard.
Fixes#1901
The sinfo function declared in sinfo_instance.h creates a static sinfo
object instance and returns a pointer to the caller.
- kernel timer and platform support to use sinfo() function to
instantiate sinfo object
- address and size of the base-hw RAM region via the sinfo API
- log_status() function in sinfo API
