Transfer quota to the session local RAM session to react to the
Quota_exceeded exception properly.
The platform driver keeps a session local RAM session for each of its
clients that is used to allocate DMA memory. A client needs to transfer
some of its quota to the platform driver, which in return transfers this
quota to the session local RAM session. As it happens allocating memory
from a RAM session involves book keeping and in this case, where the
available quota in the session did not suffice and the request was only
a few KiB, the platform driver handled the exception wrongly and did not
transfer the quota.
This problem did not surface up to now because all drivers allocate DMA
memory in larger chunks and the book keeping overhead was of no
consequence as the initial quota transfer probably covered the overhead.
Fixes#2316.
This commit includes changes to the Nic::Session_component interface.
We now pass the entire env to the component instead of only ram, rm and
the ep because we need the env to open connections from within the
Session_component implemenation. So far only the cadence_gem driver
needs this, though.
Issue #2280.
This patch eliminates the need for a global allocator by passing the
parent-service registry as argument to the 'Slave::Policy' constructor.
Fixes#2269
This commit enables compile-time warnings displayed whenever a deprecated
API header is included, and adjusts the existing #include directives
accordingly.
Issue #1987
To better support non-blocking terminal components, let the
'Terminal::Session::write()' function return the number of bytes
actually written.
Fixes#2240
Merge the platform-specific files and classes (they merely aggregated
themselves) so that each platform provides merely one class
Sd_card::Driver. Also, the Sd_card::Driver_base class is introduced for
the generic parts of Sd_card::Driver.
Ref #2206
Most implementations use a Signal_handler now to acknowledge the packet
instead of waiting for the transfer completion. The exceptions to that are
the non-DMA implementations for RPI and PL180
Ref #2206
In addition to that we now busy wait, i.e. poll, for interrupts
instead of using the IRQ session. That is fine because interrupts
were only used while configuring the HDMI over I2C and are not used
while normal operation.
