Steam's gameoverlayrenderer.so relies on libX11 symbols to be available
without actually loading that library directly. This works on an unthunked
system since libGL.so depends on libGLX.so, which in turn pulls in libX11.so
at load-time. Adding a fake libX11 dependency to the libGL-guest thunks
reproduces this behavior.
Currently FEXBash only outputs `FEXBash>` which gives weird docker
vibes. This can confuse users since they no longer see what folder they
are in.
Change this so it still has the user and path exposed like a typical PS1
eg: `FEXBash-ryanh@ryanh-TR2:/mnt/Work/Work/work/FEXNew/Build>`
If the user doesn't have any of the tools necessary for handling FEX's
images then the tool would spuriously fail with `Couldn't parse rootfs definition URL.`
With zero indication as to why we removed images from the parsed json.
If the user has at least one of these tools installed then they won't
get this error message.
This function must be able to handle both guest heap pointers *and* host heap
pointers, so it only forwards to the native host library for the latter.
This is because Xlibint users allocate memory using internal macros aliasing
to libc's malloc but then they free using the function XFree. For libX11,
this is not a problem since the allocation happens in a thunked API function
(and hence on the host heap), but if a function from an unthunked library
accesses Xlibint, it will allocate on the guest heap.
One notable example where this was encountered is XF86VidModeGetAllModeLines.
Necessary for tests that depend on the state of the running context.
Since we support an SSE mode and an AVX mode, the FPR store truncate
test will fail on hosts that don't support AVX as the register offsets
are going to be different between the two. So we can conditionally
enable support for these tests.
In the event that the host doesn't support the requirements for running
AVX-enabled applications (SVE2 with at least 256-bit wide vectors) but
still wanted to run regular SSE-enabled applications, they would be
taking a performance hit due to a load/store pessimization (necessary in
order for 256-bit loads/stores to work)
However, we can add an alternate view into the xmm data that would allow
those hosts to use the previous optimization, while still supporting
AVX-capable hosts.
In most cases we aren't using JIT symbols but still creating the perf
map file.
Early check if we should generate the file or not, this way we stop
polluting the /tmp folder.
It's common for Linux applications that use close_range to pass in ~0 as
the last FD. This was causing FEX to spin from [2, ~0U] in this loop.
This would take /forever/ to run.
Change over to an ordered map and use the map's range searching and
ranged erase to more quickly remove these elements.
Fixes a hang that occurs with first time Steam setup in
steam-linux-runtime heavy application `steam-runtime-identify-library-abi`.
Removes the "Load Default Options" menu option. This option was
confusing for new users and isn't necessary anymore.
Fixes the "Load Default" option so it actually populates the full
configuration layer in the face of partial configuration.
This is a /very/ common use case for new users that ran through
FEXRootFSFetcher, where the only configuration set is the RootFS.
The configuration would be visually confusing since the visual
representation for missing options wouldn't reflect their default
configuration state. "TSO Enabled" is an example where it would appear
disabled in the GUI, but it is default enabled.
Also fixes the issue that the default configuration window would just be
a 320x240 floating window in the center of the screen. This is due to
the window being a floating sub window in the dockspace by default, and
not docked.
Instead just remove the dockspace, it isn't serving us any purpose.
This means the child configuration window now maximizes to the window
size which is the desired behaviour from default.
Additionally only save the config file once. While the msg dialog is
open (2 seconds while it is open, or escape to make it go away
immediately) the program won't save the file again. This fixes an issue
that if you used the shortcut key to save the file, it would save the
file at the refresh rate of your screen. Which is 144hz on my setup, so
it spams my filesystem quite heavily.
Main options here are `-y` and `-a`.
Passing both will allow the user to download the exact match image, use
it as-is, and set the config to use the rootfs by default.
Additional options `--distro-name` and `--distro-option` allows one to
select a particular distro version.
eg: `FEXRootFSFetcher -y -a --distro-name=ubuntu --distro-version=22.04`
* Will download the first Ubuntu 22.04 compressed in the json list
** Priority of erofs or squashfs depends on order in json and what the
host supports
While we were getting the application name for the application layer, we
were failing to store the filename for telemetry.
Save the filename we get for application layers and store it for the
telemetry file.
Otherwise these were just alway ending up as wine or wine-preloader.
