This patch reduces the number of exception types by facilitating
globally defined exceptions for common usage patterns shared by most
services. In particular, RPC functions that demand a session-resource
upgrade not longer reflect this condition via a session-specific
exception but via the 'Out_of_ram' or 'Out_of_caps' types.
Furthermore, the 'Parent::Service_denied', 'Parent::Unavailable',
'Root::Invalid_args', 'Root::Unavailable', 'Service::Invalid_args',
'Service::Unavailable', and 'Local_service::Factory::Denied' types have
been replaced by the single 'Service_denied' exception type defined in
'session/session.h'.
This consolidation eases the error handling (there are fewer exceptions
to handle), alleviates the need to convert exceptions along the
session-creation call chain, and avoids possible aliasing problems
(catching the wrong type with the same name but living in a different
scope).
This patch replaces the 'Parent::Quota_exceeded',
'Service::Quota_exceeded', and 'Root::Quota_exceeded' exceptions
by the single 'Insufficient_ram_quota' exception type.
Furthermore, the 'Parent' interface distinguished now between
'Out_of_ram' (the child's RAM is exhausted) from
'Insufficient_ram_quota' (the child's RAM donation does not suffice to
establish the session).
This eliminates ambiguities and removes the need to convert exception
types along the path of the session creation.
Issue #2398
The usb_drv must always check the device pointer in all session facing.
methods. A errorneous client can otherwise trigger a page-fault in the
driver.
Fixes#2133.
- use the correct memory free functions on errors
- report packet submit errors
- rename 'Usb::Packet_descriptor::transfer.timeout' as
'Usb::Packet_descriptor::transfer.polling_interval'
Fixes#2135
Session_label constructor now takes a bare string rather than a
serialized argument buffer.
Replace all instances of previous constructor with 'label_from_args'
function.
Issue #1787
* remove all 'Genode::env()' calls
* use attached roms to read configuration
* use compoenent framework
* remove all PDBG, PINF, PWRN macros
Issue #1987Fixes#2019
Currently the report name is used implicitly as first xml node name for the
report. This is inconvenient if one component wants to generate various xml
reports under various names (e.g. to steer consumers/clients slightly
differently) but with the same xml node tree structure.
Fixes#1940
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.
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
