* Wait for for completion before return from 'execbuffer2'. This makes
buffer execution synchronous.
* Because the Iris driver manages the virtual address space of the GPU
and creates one GEM context for each batch buffer we have to map/unmap
all buffer objects before and after batch buffer execution.
issue #4260
This patch adds a switch to internal poll function in libssh that
allows to force this function to immediately return without actually
polling for data and in consequence processing this data. This switch
is used to avoid calling callback functions when flushing output
streams which caused locks due to recursive access to internal
ssh_terminal sessions registry.
Issue #4258
This patch allows to replace sftp packet read and write with
completely asynchronous versions needed to properly hook in existing
ssh_terminal implementation.
Issue #4258
* Switch mesa support from DRI to gallium
Supported drivers are
- softpipe (Sebstian Sumpf)
- iris for Intel GPUs (Alexander Boetcher)
- etnaviv for Vivante GPUs (Josef Söntgen)
* Mesa's generated files are placed into 'contrib/mesa-<hash>/generated'
and are cloned per default from a separate Git repo in order to avoid
hash updates upon package build. In case you need to generate files
yourself use
! prepare_port mesa GENERATE_FILES=1
issue #4254
Support for iris and etnvaviv
* entaviv:
- libdrm on FreeBSD is not prepared for !PCI (and libc our is missing
<sys/pciio.h>
- missing <sys/types.h> include in xf86drmMode.c
- etnaviv relies on linux header files - dummy in $(INC_DIR)
- IOCTL FreeBSD ↔ Linux have swapped IO/OUT bit
- O_CLOEXEC differs between FreeBSD ↔ Linux
issue #4254
- remove redundant file system factory
- remove dead code block
The code was guarded by preprocessor directives checking whether the
contrib code define "_USE_MKFS" is 1. As "_USE_MKFS" is not set one
for our port of FAT, the code was never executed and can be removed.
- remove uneffective config attributes
Apparently, the former XML attributes to the plugin 'drive' and
'codepage' had no effect. I tested them in a scenario with the VFS
block server on a disk-image boot-module as back end. Regardless of
the 'drive' value, the block session label was always "0". Regardless
of the 'codepage' value, the FAT on the disk image succeeded to mount
when not using '--codepage' for 'mkfs.fat' and failed to mount when
using '--codepage' to specify a supported but foreign codepage for
'mkfs.fat' (e.g. "720").
Ref #4220
There was one global static constructor:
! namespace Fatfs { static Constructible<Platform> _platform; }
This caused applications that used the lib or the <fatfs> VFS plugin to end up
in an uncaught exception due to Genode::Component complaining that method
'construct' returned without executing pending static constructors if they
didn't call Genode::Env::exec_static_constructors().
As the use of Genode::Env::exec_static_constructors() is discouraged in Genode,
this commit rather moves the '_platform' object to the scope of the
initializing function and introduces a global static pointer to the object that
gets set by the initializing function. Although this prevents the exception, it
is, technically speaking even worse than the former solution as the new pointer
isn't checked for validity in contrast to the 'Constructible' object.
However, so far, I don't see a clean solution to this problem without the need
for Genode::Env::exec_static_constructors().
Fixes#4220
For mesa-21 the client takes care and manages
the virtual address space of the vGPU by itself and the intel/gpu driver
can't add silently a guard page anymore. Move the patch to the drm/ioctl
of the former mesa version.
Issue #4148#4233
The symlink implementation wrongly constructed a 'Sync' object within
the context of a monitor call. The 'Sync' constructor indirectly
depended on libc I/O for obtaining the current time, ultimately
resulting in a nested attempt of a monitor call. This could be
reproduced via the base.run script:
$ cd /home
$ ln -s a b
The 'ln' command resulted in the following log message:
[init -> /bin/bash -> 7] Error: deadlock ahead, mutex=0x10ff8c70, return ip=0x500583a7
The patch fixes the problem by splitting the single monitor call into
two monitor calls and moving the construction of the 'Sync' object
in-between both monitor calls, thereby executing the constructor at the
libc application level.
Fixes#4219
- Patch the XHCI model in order to handle frame wrapping correctly. For
this adjust 'mfindex_kick' to the correct period (same, before, or after
'mfindex').
- Flush EP when it is stopped, this causes all pending packets for the EP
to be acked. Correct counting of packets in flight.
- Add BEI patch by Josef.
issue #4196
Because qemu-usb allocated host devices after 'USB_HOST_DEVICE' in the
object array and 'USB_WEBCAM' is loacated after 'USB_HOST_DEVICE' the
webcam model can overwrite an already allocated pass-through device. As
a solution add the 'USB_FIRST_FREE' to make it clear from where host
devices can be allocated. Also increase the number of supported host
devices to eight.
fixes#4182
This patch avoids the repeated warning "read blocked until lwIP
interface is ready" by printing the message only once. Otherwise,
the log is flooded with those warnings when falkon web browser
is started on Sculpt OS without network connectivity.
With this commit libcrypto does not use ARM NEON extension as long as
SPECS includes "neon". arm_v7a does declare "neon" per default while
arm_v8a does.
Issue #3773
Note, OpenSSL now comes as one combined depot archive *openssl* that
replaces the former *libssl* and *libcrypto* archives. The libraries are
still separate binaries for compatibility with legacy software.
Issue #3773
Be more in line with the original host implementation in Qemu and
buffer transfers. Having transfers in-flight helps to smoothen playback
in case other components utilize the CPU.
Issue #4018.
Linux as well as Windows guests want queue to a varying number of
transfers, where each transfer only covers one transaction (iso frame).
The best results were obtained by following that behaviour rather
than queuing multiple iso frames per requests (like is done with OUT
transfers).
The number of requests queued is increased to 32 while the number of
packets per reques is decreased to 1.
Issue #4018.
