You can now mmap a file as private and writable, and the changes you
make will only be visible to you.
This works because internally a MAP_PRIVATE region is backed by a
unique PrivateInodeVMObject instead of using the globally shared
SharedInodeVMObject like we always did before. :^)
Fixes#1045.
We now have PrivateInodeVMObject and SharedInodeVMObject, corresponding
to MAP_PRIVATE and MAP_SHARED respectively.
Note that PrivateInodeVMObject is not used yet.
Add an extra out-parameter to shbuf_get() that receives the size of the
shared buffer. That way we don't need to make a separate syscall to
get the size, which we always did immediately after.
This feels a lot more consistent and Unixy:
create_shared_buffer() => shbuf_create()
share_buffer_with() => shbuf_allow_pid()
share_buffer_globally() => shbuf_allow_all()
get_shared_buffer() => shbuf_get()
release_shared_buffer() => shbuf_release()
seal_shared_buffer() => shbuf_seal()
get_shared_buffer_size() => shbuf_get_size()
Also, "shared_buffer_id" is shortened to "shbuf_id" all around.
Also, we have now two new resolutions - 1368x768 and 1366x768.
The 1366x768 resolution is currently not supported but is good
for testing a failed resolution setting.
Now we return a boolean value from set_resolution() in the Compositor
and Screen class. Also, the WindowServer IPC now returns a richer result
after changing the resolution, which can be used in clients later.
Now we check before we set a FBResolution if the BXVGA device is capable
of setting the requested resolution.
If not, we revert the resolution to the previous one and return an error
to userspace.
Fixes#451.
This is causing FilePicker to log a bunch of debug noise due to the
missing support for tree models in SortingProxyModel and it's not
helping anyone so let's just disable it.
This needs fixing in SortingProxyModel.
Let's temporarily disable the boosting calls until we have a solution
for boosting in the new multi-user world. The error messages keep
confusing people into thinking they're doing something wrong.
