- move metadata specific to isochronous transfers from the descriptor
into the content of USB-session packets
- restore support for 32 in-flight packets in the USB C API
Fixes#4749
This patch ultimatedly removes format strings from Genode's base API.
Users of the former base/snprintf.h and base/console.h headers may
use the free-standing 'format' library hosted in the ports repository.
Fixes#2064Fixes#3869
This little library implements rudimentary format-string support. It is
useful for porting 3rd-party code that ought not depend on a full libc.
Issue #2064
In case the packet is erronous the value of 'actual_size' can be
invalid and using it may lead to a page-fault due to out-of-bounce
access.
With this commit access is only performed on successful packets.
Fixes#4763.
The 'file_size' type denotes the size of files on disk in bytes. On
32-bit architectures it is larger than the size_t, which refers to
in-memory object sizes.
Whereas the use of 'file_size' is appropriate for ftruncate and seek, it
is not a suitable type for the parameters of read/write operations
because those operations refer to in-memory buffers.
This patch replaces the use of 'file_size' by size_t. However, since it
affects all sites where the read/write interface is uses, it takes the
opportunity to replace the C-style (pointer, size) arguments by
'Byte_range_ptr' and 'Const_byte_range_ptr'.
Issue #4706
Prior to this change the libdrm Lima implementation supported the
creation of multiple contexts where each context, however, was
treated as the same client like it was done in the Lima driver
itself.
With this commit each context becomes its own client while the
main context always performs all buffer object related allocation
and the other context import each needed BO before submitting.
Fixes#4760.
Sync file-descriptors a purely virtual and are not known by the libc and
should be only accessed by 'drm_poll'. To prevent accidental access move
them to range never used by the libc fd allocator.
Issue #4760.
* 'map_buffer', GTT mappings are currently not used by Iris
* 'set_tiling', tiling is currently not used by Iris because there are
no GTT mappings
issue #4713
lwip uses a sophisticated reference-counting scheme in chains of pbufs,
which the former manual implementation of read() for TCP data broke.
Using pbuf_free_header() keeps the chain intact and also relieves our
implementation from the burden of "offset" maintenance.
Fixes#4722
Some USB devices (e.g., webcams) fail to deliver their configuration
descriptor early after power-up. Testing revealed that retrying the
requests usually succeeds on second or third attempt.
Fixes#4739
