- 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.
Normally this bench has read all data to one large buffer and
than written it back to the drive but for SATA 3 (6 Gbps) benchmarks
we would need a buffer of approximately 1.2 GB to do it this way
and reach 2 seconds bench time. Thus we use a buffer of SATA request size
and override it with every request.
This commit splits the Fiasco.OC-specific extension for the cli_monitor
into one for the Arndale platform, and one for all others. On Arndale
we add the cpu_frequency command beside the ones defined on all platforms.
Initialize and limit port speed to 3 Gbps in general because the Seagate
Barracuda 1TB throws much errors with 6 Gbps by now.
Try all port speeds from the highest to the lowest as long as debouncing fails
and try them all again in this order when falling back to slower debouncing.
Try to recover from all types of interface error.
When a port was recovered from an error during a NCQ command
get the last LBA that was accessed successfully and continue command from
this point.
Use a platform driver through the 'Regulator' service to do CMU and PMU config.
Switch off verbosity by default.
To raise expressiveness of the benchmark it dynamically adjusts the
transfer amount at any test to get a result that was measured
over a transfer time of 2000 ms at least and 2300 ms at a max.
* Retry debouncing first with a higher trial time and if this also doesn't
work with lower link speed additionaly.
* Ignore DevSlp feature because it isn't needed anyway as far as i can see.
* Relax some restrictions according the feedback of the drive as far as it
seem to have no effect in Linux too
Fix#753
* Implements platform driver for Arndale providing Regulator for CPU clock
* Implements a cpu frequency scaling test using the affinity test
* Fixes#770
Commit c464ee2e6673fe328a8717342dca30f3b0204cb8 removed the RX_BUF_SIZE from
the NIC session interface. Mistakenly, the nic_loopback server was missed
when doing this change.
In fact, the sizes were the same the whole time, but by using
the same enum in both cases to instantiate the Packet_stream_tx
and Packet_stream_rx members of the e.g. RPC object, it allows
for more flexible generalization between e.g. source or, sink
objects, when programming event-driven, and implementing generic
handlers for their signals.
Just use configuration values when existent, otherwise when no configuration
is given use the default values. When an incomplete configuration is given,
take the supplied ones, and for the rest the default ones. Fix#762
This patch introduces a new platform 'linux_arm' for building and running
Genode/Linux on an ARM device.
Known limitations:
- libc 'setjmp()'/'longjmp()' doesn't currently save/restore floating
point registers
Fixes#746.
This is a first version of the AHCI driver. It supports SATA HDDs
with UDMA-133 only, up to 6 Gbps and native command queueing.
The more blocks one transfers with one command, the higher is the
chance that the driver produces a fatal handshake error. Nevertheless
the driver is stable with one block per ATA command. Although NCQ is
used the driver doesn't queue multiple commands simultanously.
The driver was tested with a western digital HDD "WDC WD2500BEVS-08VAT1
13.01A13" (250 GB) with hw_arndale (run/ahci) and foc_arndale
(run/ahci, run/l4linux: dd). SSDs were not tested.
Fix#706
Changes GPIO session interface to a one-GPIO-pin-per-session style. Moreover,
this commit introduces a generic driver interface for GPIO drivers. Thereby
generalizes root- and session component for GPIO.
A run script which sends raw ethernet packets from the host machine to the
target machine. Three tests are implemented:
- The network_stat instrumented driver of usb_drv and net_drv
are used to get the raw receive performance of the network driver.
- A simple nic_session client is receiving from the un-instrumented network
driver raw ethernet packets.
- A bridge is added between driver and simple nic_session client.
