Interfaces that have been claimed by a component always have to be
released when the session is closed in case the component
malfunctioned.
Fixes#1869.
- Use 'label' attribute to identify device instead of
bus/dev and vendor_id/product_id
- Implement release_interface RPC
- Report 'label' as well as 'bus' and 'dev'
- Add policy handling to raw driver (includes reconfiguration
at runtime)
- Use own memory backing store for large DMA allocations
Issue #1863.
platform_execute() is used to initially switch the stack of a
routine/task. While Thread_base::alloc_secondary_stack() properly aligns
the returned stack pointer the x86_64 assembler implementation did not
comply to stack frame management specified in the ABI.
The used (and most simple) stack-alignment check may pass a float to a
varargs function on x86, which requires the compiler to properly save
some XMM registers on stack.
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
Instead of returning pointers to locked objects via a lookup function,
the new object pool implementation restricts object access to
functors resp. lambda expressions that are applied to the objects
within the pool itself.
Fix#884Fix#1658
Do not use slabs for allocations above 64KB, this seems to lead to memory
corruptions and the error described in issue #1613 under certain circumstances.
fixes#1613
Removed the Nic::Driver implementation. All nic servers now inherit from
Nic::Session_component. Packet stream signals are dispatched to
the 'handle_packet_stream' function within a session component. Thus, nic
servers now have direct access to the packet stream channels, making handling
more flexible.
Adjusted nic_loobpack, dde_ipxe, wifi, usb, lan9118, Linux nic, and OpenVPN to
the new interface.
Fixes#1602
With the server framework this becomes unnecessary. Also when the 'platform_drv'
has a lower priority, signaling will cause a constant load that starves the
'platform_drv'.
Fixes#1594
The report lists all connected devices and gets updated when devices are
added or removed.
Example report:
<devices>
<device vendor_id="0x17ef" product_id="0x4816"/>
<device vendor_id="0x0a5c" product_id="0x217f"/>
<device vendor_id="0x8087" product_id="0x0020"/>
<device vendor_id="0x8087" product_id="0x0020"/>
<device vendor_id="0x1d6b" product_id="0x0002"/>
<device vendor_id="0x1d6b" product_id="0x0002"/>
</devices>
There is no distinction yet for multiple devices of the same type.
The report is named "devices" and an example policy for 'report_rom' would
look like:
<policy label="vbox -> usb_devices" report="usb_drv -> devices"/>
The report only gets generated if enabled in the 'usb_drv' configuration:
<config>
<raw>
<report devices="yes"/>
</raw>
</config>
Fixes#1506
- send a 'state_change' signal on session creation if the device is
already attached
- evaluate the status code of a finished asynchronous operation
- return the number of actually transferred bytes for control transfers,
too
Fixes#1490
This patch adds const qualifiers to the functions Allocator::consumed,
Allocator::overhead, Allocator::avail, and Range_allocator::valid_addr.
Fixes#1481
A Nic::Session client can install a signal handler that is used to
propagate changes of the link-state by calling 'link_state_sigh()'.
The actual link state is queried via 'link_state()'.
The nic-driver interface now provides a Driver_notification callback,
which is used to forward link-state changes from the driver to the
Nic::Session_component.
The following drivers now provide real link state: dde_ipxe, nic_bridge,
and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not
support link state and always report link up.
Fixes#1327
The alias is rather Linux-specific and also prevents particularly
tailored jiffies implementations. For the existing dde_linux ports (usb
and lxip) we just define jiffies to be dde_kit_timer_ticks with a
preprocessor macro.
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.
