f171bc5050 Remove loader and qpluginwidget
The original use cases of the loader have long been covered by the
dynamic init. The only substantial client of the loader remained to be
the qpluginwidget. However, the qpluginwidget was supported only by the
Arora web browser. But the blending of plugins with websites ultimately
remained a tech demo, and Arora has been replaced by Falkon.

179b3eb7e4 libdrm/iris: make locking more fine grained
When more than one thread are accessing the DRM interface it is not wise
to use global locking, especially when a pthread is executing a batch
buffer and waits for a completion signal in the VFS-plugin. In case the
EP gets stuck in the global lock, no progress is made. Therefore:

* use _drm_mutex only where strictly necessary
* use special _exec_mutex to protect buffer execution (per context)
* print warning when two threads try to execute a buffer in the same
  context

dca3b12109 libdrm: update to version 2.4.120
Prerequisites for Mesa 24.0.1

* generic:
  * add patch to retrieve PCI/Platform information from Genode side of the DRM
    interface (in drmGetDevice2)
  * add generated 'fourcc' file

* iris:
  * report back-end (currently 'i915', 'xe' is unsupported)
  * add various I915_CONTEXT_PARAM* and I915_PARAM*
  * allocate 'Buffer's starting with ID 1 (0 is invalid)
  * enforce 48-bit-address limit on unmap also
  * disable I915_EXEC_FENCE_ARRAY array check, because we do not support
    sync objects right now and rendering in synchronous

* etnaviv:
  * create 'Fenceobj' only *once* for each GPU context

344831ec06 curl: update to version 8.7.1
This commits updates the contrib sources to version 8.7.1.

This version requires more random entropy as it queries OpenSSL
about the current random state and will bail if it is not sufficient.
Doubling the content of the '<inline>' VFS plugin as used in static
configurations seems satisfactory.

Furthermore DNS resolving needs a configured '<pipe>' plugin to work
properly.

7ec08af6d9 usb: session renewal & new client API
Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.

The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.

The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.

This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.

The adaptations necessary target the following areas:

* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
  reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
  with the new policy rules of the USB host controller driver

9a65e4f607 mesa: generalize binder memory management
This patch was back ported from upstream Mesa and generalizes the memory
management of buffer objects used by the binder. Before this patch the
binder was treated as a special case where buffer objects were allocated
with a simple "next block or wrap" allocator. With this commit the
binder now uses the vm_heap allocators as done by all other buffer
allocations which leads to issues with reference counting and object
destruction being resolved.

Original commit message:

We're moving towards a path where all contexts share the same virtual
memory - because this will make implementing vm_bind much easier - ,
and to achieve that we need to rework the binder memzone. As it is,
different contexts will choose overlapping addresses. So in this patch
we adjust the Binder to be 1GB - per Ken's suggestion - and use a real
vma_heap for it. As a bonus the code gets simpler since it just reuses
the same pattern we already have for the other memzones.

35638568c5 qemu-usb: access I/O buffers directly
This commit replaces the mapping of DMA buffers and gets rid of the
bounce-buffer handling, which was introduced to prevent data
corruption noticed when utilizing USB storage with Windows 10 guests,
with accessing the buffers directly.

Due to the way Windows 10 at times manages its DMA memory (many small
pieces instead of few larger ones) the unbounded registry becomes a
problem when containing stale entries.

Changing the 'qemu-usb' implementation allows for using 'read_dma'
and 'write_dma' directly.

77b0e10e88 vfs/ram_file_system: deferred unlink
This patch changes the unlink operation of the ram fs to defer the
destruction of a file until it is no longer referenced by any VFS handle.
When unlinked, the file no longer appears in the directory. But it can
still be opened and accessed.

With this change, a parent process of a Unix-like subsystem becomes able
to pass the content of an unlinked file to a forked child process. This
mechanism is required when using the 'exec' command in Tcl scripts.

Another use case is the 'tmpfile()' function.

9aa0de24af libc: implement '_spinlock()' and '_spinunlock()'
FreeBSD libc code uses only a single spinlock instance and, thus there
is no obvious reason why it would need to be implemented as an actual
spinlock. _spinlock() and _spinunlock() functions are implemented with a
static pthread mutex.

6402182815 sntp_client: add DNS lookup option
This commit adds a new configuration option, `dst_addr` to the
'sntp_client' that accepts either an IP address or a DNS hostname. If a
DNS hostname is provided, the 'sntp_client' will resolve the IP address
before each SNTP request. The 'dst_ip' configuration option is
deprecated but kept for compatibility until 'dst_addr' is fully adopted.

xsd/net_types.xsd: add Net_address type
sntp_dummy_rtc: adjust configuration to use pool.ntp.org

916bd88e5e base: extend PD session by system_control_cap
Per Affinity::Location a system control cap can be requested. The capability
provides an RPC interface to request and set Cpu_state, as provided by the
former Pd::managing_system(Cpu_state) method. Invocation of those system
control capabilities then *can* (see below) be executed on the desired CPU
as described by Affinity::Location.

The system control cap will be invalid for kernels that don't support
system_control/managing_system functionality at all.

The system control cap will be ever by the same, e.g. ignoring the
Affinity::Location parameter, if the used kernel doesn't support or doesn't
require the feature to execute the system control per CPU.

The commit is a preparation step to add guarded and selective x86 MSR
access per CPU.

264160797d qemu-usb/webcam: cache large allocation of libyuv 2023-10-04 13:22:06 +02:00

0d868515a5 libyuv: add support to overwrite default allocator
Internally libyuv uses malloc & free for short time dynamic memory
allocation during image transformation. The converted images are
such large, that the Libc allocator will create and destroy new Genode
dataspace per image.  In time sensitive code paths, the overhead can be
noticeable by the caller of the image transformation.
The patch adds the option to register callbacks in the libyuv library to
implement the image allocation by users of the library. They may implement
caching strategies to avoid the overhead, e.g. as seen with qemu-usb and
the webcam model.
