This is a follow-up commit to the libc update. The FreeBSD
implementation of sigset or sigaction calls the __libc_sigaction now.
The patch fixes the SIGWINCH handling for Vim when interactively
resizing the terminal window.
Fixes#3424
- use priorities solely with nova
- handle exceptions during vCPU creation
- avoid assertion in vga_vbda
- silence compiler warnings about outdated register keyword
Issue #3111
This prevents
error copying "bin/libm.lib.so": no such file or directory
error copying "bin/posix.lib.so": no such file or directory
when running "make run/noux" from an empty build directory.
either
- due to poor signal performance of base platform
- due to being to less prioritized
- due to schedule overload
- due to using time sources of different physical CPUs
Issue #3111
To enable the use of uncached DMA buffers as RX and TX communication
buffers in between driver (service) and client, introduce a cache
attribute in the constructor of Nic::Session_component
Ref #3291
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.
Fixes#3208
As a preparatory step for introducing the new block-client API, we have
to turn the 'Block::Connection' into a class template. The template
argument will be used to tie an application-defined job type to the
block connection.
Issue #3283
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.
First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.
Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.
The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.
At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).
