Use NATIVE MAX ADDRESS EXT to retrieve last block for LBA48. Also check not only
for enabled LBA48 support but for the 'host protected area' bit before using the
LBA48 version. This is because the high order byte (HOB) data retrieval is
broken in Qemu.
Fixes#761.
Split the netperf run script into 3 ones so that it can be used more easily
in an automated run.
It is solely for foc_arndale by now.
l4linux_netperf.run - use nic via usb2.0
l4linux_netperf-usb30.run - use nic via usb3.0
l4linux_netperf-bridge.run - use nic via usb3.0 + bridge
Split the netperf run script into 3 ones so that it can be used more easily
in an automated run.
netperf.run - use native nic driver (x86) or usb2.0 (arndale, panda)
netperf_usb30.run - use native nic driver (x86) or usb3.0
netperf_bridge.run - use native nic driver (x86) or usb3.0 (arndale) and bridge
Issue #794
- use the generic 'crt0.s' for Linux
- move the read-only '__dso_handle' definition into the '.text' section
- move the '__initial_sp' definition into the '.bss' section
- remove the '_main_utcb' definition
Part of #766.
Until now the print procedure call in the Log_session_component
did contain a hardcoded 'init' string. Adding a method to filter
the session args to prefix the label and labelling the initial
Cpu_connection for the init-process enabled us to remove the
hardcoded string.
Fixes#789.
The given number of bytes is consumed but not actually allocated. This
feature may be used for accounting and use memory within core which is
in fact provided by a session client.
Fixes#792.
* Always download md5sum file and check downloaded binaries
* Extend sleep time in l4linux_netperf script, so that DHCP has enough time
* Fix regexp rule in l4linux_netperf run script to work with MAC addresses
containing only numbers
Fix#787
Sometimes the ports are not freed up quick enough by the host system after the
first test finished. The port restriction is mainly required for qemu, so don't
use it for bare metal hardware tests.
* Add platform_drv for usb_drv, sd_card_drv and ahci
* Add ahci driver and part_blk on top of it
* add linux instance using SATA partition
* add VIM using SATA partition
The window scale option (http://tools.ietf.org/html/rfc1323) patch of lwIP
definitely works solely for the receive window, not for the send window.
Setting the send window size to the maximum of an 16bit value, 65535,
or multiple of it (x * 65536 - 1) results in the same performance.
Everything else decrease performance.
We will have to check this window scale patch before using higher values.
Minor speed improvements of ~6Mbit. Additionally a ethernet frame fits now
into one memory allocation per pbuf. Beforehand two were allocated - one being
1514 bytes and another one being 2 bytes (monitored by instrumenting copy loop
in libports/src/lib/lwip/platform/nic.cc).
lwip reports via getsockopt the size of the default size of the receive buffer
to the netperf server. lwip returns 2GB and netperf server uses this value to
allocate some buffers - which of course fails with out of memory.
Reduces the "default size" to some smaller value.
With the commit we are not forced anymore to (but still can) use specific
netperf client options regarding memory allocations of the receive buffer.
MAERTS is STREAM backwards and effectively lets the netserver sends the packets
to the netperf client. So, TCP_STREAM measure the receive performance of the
lwIP stack on Genode and TCP_MAERTS the send performance of the lwIP stack
on Genode.
