2020-10-20Revert "qemumips: use 34Kf-64tlb CPU emulation"Victor Kamensky
This reverts commit 6a9568401cbf8bed89d1f63dae61a07a83a20b50. Will be replaced with upstreamed solution instead, that just bumped number of TLBs to 64 in original 34Kf CPU model. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2020-10-08qemumips: use 34Kf-64tlb CPU emulationVictor Kamensky
In order to improve performance of qemumips autobuilder test runs, let's use 34Kf-64tlb cpu type that was introduced in OE version of qemu. 34Kf-64tlb cpu type is identical to 34Kf but it has 64 TLBs configure vs original 16 TLBs. The change in number of TLBs in emulated CPU reduces TLB trash and reduces number of times TLB refill kernel code runs, and therefore siginificantly improves tests execution time. Note 34Kf-64tlb qemu cpu type does not exist in upstream, so far it is added as patch in OE. See qemu 34Kf-64tlb cpu addition commit for more details.

2020-08-01qemumips: Use 34Kf CPU emulationKhem Raj
Few years ago we switched to using mips32r2 tunings for qemumips however the default CPU emulation still remained 24Kf which is not optimal for mips32r2 ISA for qemu [1], therefore switch to recommended 32Kf for CPU emulation when running qemu in system mode Boot time to console is ~1s faster with this setting, hopefully this should speed up qemumips in general [1] https://www.qemu.org/docs/master/system/target-mips.html#preferred-cpu-models-for-mips-hosts Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

qemumips,qemumips64 and x86 based machines include kernel-modules by default. Remove the kernel modules from RRECOMMENDS to make it consistent across the machines.

2016-12-13Use weak assignment for SERIAL_CONSOLES in qemu configuration filesChen Qi
Use weak assignment for SERIAL_CONSOLES in qemu configuration files so that the value could serve as a default value and could be easily overridden in configuration files like local.conf. When using the default value for SERIAL_CONSOLES in qemux86-64,we would have annoying messages on console complaining about respawning getty on ttyS1. Although the value is set by purpose, at least we need to provide an easy way to override it. Signed-off-by: Chen Qi <Qi.Chen@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

2015-08-24qemurunner: Use two serial ports and log console with a threadRandy Witt
qemu can freeze and stop responding if the socket buffer connected to a tcp serial connection fills up. This happens of course when the reader of the serial data doesn't actually read it. This happened in the qemurunner code, because after checking for the "login:" sentinel, data was never again read from the serial connection. This patch solves the potential freeze by adding a thread to continuously read the data from the console and log it. So it also will give a full log of the console, rather than just up to the login prompt. To simplify this patch, another serial port was also added to use for the sole purpose of watching for the sentinel as well as being the interactive serial port. This will also prevent the possibility of lots of debug data on the console preventing the sentinel value from being seen due to interleaved text.

2014-08-23qemumips.conf: Default to (and support) mips32r2Peter Seebach
The MIPS emulation for qemumips actually supports mips32r2: isa : mips1 mips2 mips32r1 mips32r2 We should probably use that tuning file. This implicitly changes the default value of DEFAULTTUNE to mips32r2. Signed-off-by: Peter Seebach <peter.seebach@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2011-07-22conf/machine/tune: Overhaul tune include file variablesRichard Purdie
There is currently consideradble confusion over how the tune files operate and how these interact with the rest of the build system. This update/overhaul changes things so the tune files are primarily resonsible for setting: TUNE_ARCH - What was formerly set as TARGET_ARCH and is the value that represents the architecture we're targetting. TUNE_PKGARCH - The value that represents the tune confuration that this set of tune parameters results in. This allows the significant improvement that the core can now always determine the target architecture value, even when TARGET_ARCH needs to be reset to something different and likewise, there is one package architecture variable the core can reference allowing simplification of the BASE_PACKAGE_ARCH, PACKAGE_ARCH and FEED_ARCH variables.

2010-05-18Move all QEMU machines to use a common kernel recipe set and versionJoshua Lock
The different kernel recipes encapsulate functionality groups for machines, therefore it makes sense to have all the QEMU machines using the same kernel recipe. Switch the QEMU machines to default to the "linux" recipes for their kernel and bump the latest recipe from linux-2.6.32 to 2.6.33. Signed-off-by: Joshua Lock <josh@linux.intel.com>
