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.
The KDB UART driver uses the Fiasco(.OC) kernel debugger console as backend
for input and output. This is useful in the case that only one UART is
available.
Fixes#665.
Remove the 'epit' variable from the generic imx31 and imx53 specification,
and only add it to base-hw specific i.MX specs. Thereby the EPIT timer
library gets build for base-hw only.
Moreover, fix some const-ness issues in the platform_timer implementation
for the EPIT timer.
Fixes#688.
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.
Hereby, the base libraries have been reduced to the following few
libraries:
- startup.mk contains the startup code for normal Genode processes.
On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
processes
Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.
Fixes#18
By using the build system's library-selection mechanism instead of many
timer targets with different 'REQUIRES' declarations, this patch reduces
the noise of the build system. For all platforms, the target at
'os/src/drivers/timer' is built. The target, in turn, depends on a
'timer' library, which is platform-specific. The various library
description files are located under 'os/lib/mk/<platform>'. The common
bits are contained in 'os/lib/mk/timer.inc'.
The 'Timer::Session::msleep' function is one of the last occurrences of
long-blocking RPC calls. Synchronous blocking RPC interfaces turned out
to be constant source of trouble and code complexity. I.e., a timer
client that also wants to respond to non-timer events was forced to be a
multi-threaded process. This patch replaces the blocking 'msleep' call
by a mechanism for programming timeouts and receiving wakeup signals in
an asynchronous fashion. Thereby signals originating from the timer can
be handled along with signals from other signal sources by a single
thread.
The changed interface has been tested on Linux, L4/Fiasco, OKL4, NOVA,
L4ka::Pistachio, Codezero, Fiasco.OC, and hw_pbxa9. Furthermore, this
patch adds the timer test to autopilot.
Fixes#1
The default constructor didn't initialize all members, some of them holding
pointers. In the de-constructor the _name pointer was tried to free up, even
when it was not initialized.
Avoid any hassle for uninitialized members and just initialize it. Fixes
sporadic page fault on x86_64 base-nova.
Issue #155
Add functionality to lookup an object and lock it. Additional the case is
handled that a object may be already in-destruction and the lookup will deny
returning the object.
The object_pool generalize the lookup and lock functionality of the rpc_server
and serve as base for following up patches to fix dangling pointer issues.
The block count in DMA requests is limited to 8 bit. Therefore,
if a client requests more than 255 blocks in a single packet request,
split the request in a loop.
