Commit 6a3368ee that refactored the mode transition assembler path, and
high-level entry point, fundamentally broke that part for the TrustZone VMs.
Instead of jumping to the appropriated address, the instruction value at that
point where used as target address.
Moreover, the TrustZone part of the mode transition page was not included into
the boundary check.
Ref #1182
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.
Depending on 'src_w' and 'dst_w', different lines of a block to copy may be
32-bit aligned or not, so the alignment of each line needs to get checked.
Fixes#1111.
Don't define assembler constants inside macros, thereby calling the
corresponding macros isn't needed anymore. To prevent having to much
constants included in files where they aren't needed, split macros.s
file into a generic mode_transition.s part, and globally used macros.s.
Fix#1180
Previously this was not done before Thread_base::start(..) in
base-hw as it was not needed to have a valid cap that early. However,
when changing the affinity of a thread we need the cap to be valid
before Thread_base::start(..).
fix#1151
By now the scheduling timer was only refreshed for a new scheduling timeout
when the choosen scheduling context has changed. But we want it to be refreshed
also when the scheduled context yields without an effect to the schedulers
choice (this is the case e.g. when the idle thread gets a scheduling timeout
or a thread yields without any competitor in its priority band).
ref #1151
By using &&, we prevent the accidental copying of deallocator instances,
passed to the destroy function. We always want to take the deallocator
as reference or pointer.
For the correct integration of a QPluginWidget in a parent QWidget, with
this commit the parent QWidget's Nitpicker view is made the parent view of
the plugin's Nitpicker view.
Fixes#1173.
This commit adds a 'parent_view()' function to the loader session, which
allows to set the parent view of the subsystem's Nitpicker view.
If the function is to be used, this must get done before calling
'start()'.
Fixes#1172.
In file
src/VBox/Additions/WINNT/SharedFolders/driver/file.c
the function
static int vbsfTransferCommon(VBSFTRANSFERCTX *pCtx)
in the
VbglR0CanUsePhysPageList()
branch does not correctly evaluate the read or written bytes from
the VMM. It ever assumes that whole pages are read/written.
Workaround the bug in the Windows guest additions of Vbox until fixed
upstream by filling up the read/write buffer completely within the VMM code
of Vbox.
Fixes#1176
Genode::strncpy() enures the destination string is null terminated by
writing a null-byte. In this case, the null-bytes always overwrote the
last character of the output byte stream.
Ensures that the Exynos5 CPU is clocked equally no matter how the kernel
initialized it. This makes the result of this time critical test more
comparable.
fix#1162
Now that it is possible to resize the stack of the Genode main thread, it
is not necessary anymore to create a new Genode thread as Qt main thread.
Fixes#1134.
