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.
Additionally, we do the cleanup of the remains of a previously failed
run prior creating the run directory. Otherwise, the directly creation
may fail because of a pending bindmount.
With this patch, the thread context area RM session gets created at
program startup to have the thread context area's virtual address range
reserved right from the beginning.
Fixes#734.
This patch implies that all Genode processes try to create an RM
session. So a route to the RM service must be present even for processes
that have only a single thread. Hence, the patch contains an update of
affected components.
The parent-service registry is populated on demand by the
'Loader::Child' whenever a prior unknown service is requested. Since the
number of parent services is limited, we expect the registry to settle
after a while. However, each loader session has a private instance of
a parent-service registry. So when creating and destroying loader
sessions, parent registries will be populated again and again. We
have to make sure to discard the entries along with the destruction
of a loader session to avoid the leakage of memory.
Issue #717
Enable optinal support for double buffering in the i.MX53 framebuffer
driver. This prevents flickering in certain scenarios, where applications
directly render in the framebuffer dataspace given by the driver.
* Simplify IPU register definitions using templates
* Distinguish between i.MX53 QSB and SMD board in driver
* Support IPU specific overlay mechanism by framebuffer session extension
This commit removes an endless loop, that occurred when the sd_card driver
called usleep, or msleep on its Timer_delayer object. Fixes#705
Also fixes the same problem for the Omap4 GPIO driver.
'Gratuitous ARP' broadcast messages are used to announce newly created
IP<->MAC address mappings to other hosts. nic_bridge-internal hosts
would expect a nic_bridge-internal MAC address in this message, whereas
external hosts would expect the NIC's MAC address in this message.
The simplest solution to this problem is to just drop those messages,
since they are not really necessary.
Fixes#709.
