Open VCPU interrupts while the VCPU is in an IPC operation can badly influence
its state. That's why this commit fixes a whole bunch of places, where IRQs
weren't masked by now.
We have to take the block queue's spin lock before invoking the interrupt
routine, otherwise the AVL tree og Genode's block packet stream gets
corrupted.
If no platform thread was created before somebody destroys a thread object,
there is no valid UTCB available. Thereby, we've to check this before accessing
the UTCB when destroying a thread object.
This should ensure that the directory is created before trying to
create a file within it.
This hopefully fixes errors like the following when using parallel
builds:
checking library dependencies...
/bin/bash: line 19: var/libdeps: No such file or directory
make[5]: *** [init_libdep_file] Error 1
The Linux version of core used a part of the BSS to simulate access to
physical memory. All dataspaces would refer to a portion of 'some_mem'.
So every time when core would access the dataspace content, it would
access its local BSS. For all processes outside of core, dataspaces were
represented as files. This patch removes the distinction between core
and non-core processes. Now, core uses the same 'Rm_session_mmap'
implementation as regular processes. This way, the 'some_mem' could be
abandoned. We still use BSS variable for allocating core-local meta
data through.
Instead of allocating and freeing the space that is needed for the
kernel thread objects from core, wich is not convenient with the
quota system, platform thread now holds the space as array by
itself.
Unfortunately we cannot measure the space size by a static function
anymore, so kernel thread had to be moved from kernel.cc into its
own header. This way platform thread can use sizeof().
Fix#543
The Gentoo-specific section should be taken offline until the overlay
got updated.
Version 12.11 adds a binary package for x86_64 in addition to x86_32.
The generic 'sleep_forever()' function creates an Ipc_server object which
might not get cleaned up correctly when the thread gets destroyed and
unneeded capability references could remain and drain the capability index
allocator. With this patch a lock gets used on thread exit instead of
calling 'sleep_forever()'.
Fixes#538.
This patch reflects eventual allocation errors in a more specific way to
the caller of 'alloc_aligned', in particular out-of-metadata and
out-of-memory are considered as different conditions.
Related to issue #526.
In the recent change of the RPC-entrypoint destruction, the
'~Rpc_entrypoint' calls 'Thread_base::join'. Hence, we need to provide
an implementation wherever RPC entrypoints are used.
Revert the core-local mapping created in 'Ram_session_component::_clear_ds()'
and free the virtual memory region allocated for this mapping when a
RAM dataspace gets freed.
Fixes#416.
When finishing a block request in the L4Linux block stub driver,
we#ve to hold the queue lock before using __blk_end_request_all, or
simply use blk_end_request_all instead. Moreover, this commit simplifies
the lock/unlock behaviour when the block queue has to be stopped, or resumed.
Thanks to I. Ismagilov for these suggestions.
