I have a multicore rocket-chip system. However I'd like one of those rocket tiles to be asynchronous from the rest.
We're trying to do that with the following:
class WithTilesCrossing extends Config((site, here, up) => {
case RocketCrossingKey => site(RocketTilesKey).head.hartId match {
case 2 => up(RocketCrossingKey) map { r =>
r.copy(crossingType = AsynchronousCrossing(),
master = TileMasterPortParams())}
case _ => up(RocketCrossingKey) map { r =>
r.copy(crossingType = SynchronousCrossing(BufferParams(1)),
master = TileMasterPortParams())}
}
})
So that is the hart with hartId = 2 should be async, the rest should be synchronous.
The above, when added to our config, doesn't appear to do anything.
However, if I use the WithAsynchronousRocketTiles from src/main/scala/subsystem/Config.scala then I get all of the tiles converted to async.
So, how would I do just a single tile?
Update based on Jack's suggestion:
Trying that code straight up gave:
[error] Config.scala:189:16: not found: value crossingType
[error] r.copy(crossingType = AsynchronousCrossing(),
[error] ^
[error] Config.scala:190:11: not found: value master
[error] master = TileMasterPortParams())
[error] ^
[error] Config.scala:192:16: not found: value crossingType
[error] r.copy(crossingType = SynchronousCrossing(BufferParams(1)),
[error] ^
[error] Config.scala:193:11: not found: value master
[error] master = TileMasterPortParams())
[error] ^
[error] four errors found
Which is surprising. So I thought I might need to do the up() thing and tried this:
case RocketCrossingKey => site(RocketTilesKey).map { r =>
r.hartId match {
case 2 => up(RocketCrossingKey) map { k => k.copy(crossingType = AsynchronousCrossing(), master = TileMasterPortParams()) }
case _ => up(RocketCrossingKey) map { k => k.copy(crossingType = SynchronousCrossing(BufferParams(1)), master = TileMasterPortParams()) }
}
}
However that results in an elab error:
[error] Caused by: java.lang.ClassCastException: scala.collection.immutable.$colon$colon cannot be cast to freechips.rocketchip.subsystem.RocketCrossingParams

So still stuck on how to modify this original RocketCrossingParams on a per-tile basis and return it.
Looking at the definition of RocketCrossingKey:
case object RocketCrossingKey extends Field[Seq[RocketCrossingParams]](List(RocketCrossingParams()))
You'll notice that the type is Seq[RocketCrossingParams]. This implies (although I may be wrong), that we have 1 RocketCrossingParams per tile. In your code snippet, you are only looking at the first of the this Seq (via .head) checking if it's hartId is equal to 2, and then if so, iterating on all of the RocketCrossingKeys and setting them to AsynchronousCrossing.
Try something like the following where we iterate on them and only replace the index for the one with hartId == 2:
case RocketCrossingKey => site(RocketTilesKey).map { r =>
if (r.hartId == 2) { // or you can match on it, whatever
r.copy(crossingType = AsynchronousCrossing(),
master = TileMasterPortParams())
} else {
r.copy(crossingType = SynchronousCrossing(BufferParams(1)),
master = TileMasterPortParams())
}
}
EDIT: I missed the fact that there is both RocketCrossingKey and RocketTilesKey
So the issue here is that there are two parallel Seqs of parameters:
RocketTilesKey which gives us RocketTileParams, 1 for each tile
RocketCrossingKey which gives us RocketCrossingParams, 1 for each tile OR if there's only 1, it applies to all
It's also possible that there is no RocketTileParams containing hartId == 2, so let's handle everything appropriately:
case RocketCrossingKey =>
val tileParams = site(RocketTilesKey)
val crossingParams = site(RocketCrossingKey)
// One might assume hartId 2 == index 2 but that may not be the case
// Also there may not even *be* a tile with hartId == 2
val indexOfHartId2: Option[Int] =
tileParams.zipWithIndex.collectFirst { case (r, idx) if r.hartId == 2 => idx }
indexOfHartId2.map { idx =>
// This duplicates logic from HasTiles.perTileOrGlobalSetting
// If there's only 1, it applies to all
val crossings = site(RocketCrossingKey) match {
case Seq(one) => List.fill(tileParams.size)(one)
case many => many
}
// Back to the original answer using the proper index for hartId == 2
crossings.zipWithIndex.map { case (c, i) =>
if (i == idx) { // or you can match on it, whatever
c.copy(crossingType = AsynchronousCrossing(),
master = TileMasterPortParams())
} else {
c.copy(crossingType = SynchronousCrossing(BufferParams(1)),
master = TileMasterPortParams())
}
}
}.getOrElse(crossingParams) // If we don't even have hardId == 2, return original value
I was getting a 500 error once I moved my magento 1.9 install from an old server to a new server. The old server was running php5 and this one is on 7. I am now getting the following error and I know I have to change some of the code, but I am not sure what:
Fatal error: Uncaught TypeError: Argument 1 passed to Mage_Core_Model_Design_Package::getPackageByUserAgent() must be of the type array, object given, called in /home1/acapps/flagstuff.com/app/code/core/Mage/Core/Model/Design/Package.php on line 576 and defined in /home1/acapps/flagstuff.com/app/code/core/Mage/Core/Model/Design/Package.php:586 Stack trace: #0 /home1/acapps/flagstuff.com/app/code/core/Mage/Core/Model/Design/Package.php(576): Mage_Core_Model_Design_Package::getPackageByUserAgent(Object(Zend_Log), 'design/theme/te...') #1 /home1/acapps/flagstuff.com/app/code/core/Mage/Core/Model/Design/Package.php(262): Mage_Core_Model_Design_Package->_checkUserAgentAgainstRegexps('design/theme/te...') #2 /home1/acapps/flagstuff.com/app/code/core/Mage/Core/Model/Design/Package.php(287): Mage_Core_Model_Design_Package->getTheme('template') #3 /home1/acapps/flagstuff.com/app/code/core/Mage/Core/Model/Design/Package.php(420): Mage_Core_Model_Design_Package->updateParamDefaults(Array) #4 /home1/acapps/flagstuff.com/app/code/core in /home1/acapps/flagstuff.com/app/code/core/Mage/Core/Model/Design/Package.php on line 586
This is the code that starts on line 586 of Package.php
public static function getPackageByUserAgent(array $rules, $regexpsConfigPath = 'path_mock')
{
foreach ($rules as $rule) {
if (!empty(self::$_regexMatchCache[$rule['regexp']][$_SERVER['HTTP_USER_AGENT']])) {
self::$_customThemeTypeCache[$regexpsConfigPath] = $rule['value'];
return $rule['value'];
}
$regexp = '/' . trim($rule['regexp'], '/') . '/';
if (#preg_match($regexp, $_SERVER['HTTP_USER_AGENT'])) {
self::$_regexMatchCache[$rule['regexp']][$_SERVER['HTTP_USER_AGENT']] = true;
self::$_customThemeTypeCache[$regexpsConfigPath] = $rule['value'];
return $rule['value'];
}
}
return false;
}
Turns out I needed to change this:
public static function getPackageByUserAgent(array $rules, $regexpsConfigPath = 'path_mock')
to this
public static function getPackageByUserAgent($rules, $regexpsConfigPath = 'path_mock')
after that, it worked like a charm
Perhaps I'm going about something the wrong way. I have a number of buffers that need to get locked and unlocked as part of the behavior of a state machine. I thought it would be perfect to use a Vec of Reg to store the state from clock to clock and use a var Vec of wires to accumulate the state as the state machine goes about locking and unlocking things. Here is code similar to the code I wrote that breaks in the same way:
import Chisel._
class testvec extends Module
{
val io = new Bundle
{
val addr = Vec( 5, UInt( INPUT, 4 ) )
val enable = Bool( INPUT )
val in = Vec( 5, UInt( INPUT, 16 ) )
val out = Vec( 16, UInt( OUTPUT, 16 ) )
}
val latch = Vec( 16, Reg( init=UInt(0,16) ) )
var temp = Vec( 16, UInt(0,16) )
for( i <- 0 until 16 )
{
temp(i) := latch(i)
}
for( i <- 0 until 5 )
{
temp(io.addr(i)) := io.in(i)
}
for( i <- 0 until 16 )
{
io.out(i) := temp(i)
}
when( io.enable )
{
for( i <- 0 until 16 )
{
latch(i) := temp(i)
}
}
}
class testvec_Tests(c: testvec) extends Tester(c)
{
step( 1 )
}
object mainStub
{
def main( args: Array[String] ): Unit =
{
chiselMainTest( Array[String]("--backend", "c", // "--backend", "v",
"--compile", "--test", "--genHarness"),
() => Module( new testvec() ) )
{
c => new testvec_Tests( c )
}
}
}
Note that although this code merely has a simple loop, I need to get my combinatorial lock state at various points during the execution of the state machine each clock cycle, so that's why this simplification has those combinatorial states as the final output rather than the registers.

Are you sure of your "Vec" declaration ?
According to documentation, Vec must be declared as following I think:
val io = new Bundle
{
val addr = Vec.fill(5) {UInt( INPUT, 4 )}
val enable = Bool( INPUT )
val in = Vec.fill( 5 ) {UInt( INPUT, 16 )}
val out = Vec.fill( 16 ) {UInt( OUTPUT, 16 )}
}
I get this error when I try to retrieve items from Parse.com
In 10 attempts it failed around 6 times.
PFQuery *query = [PFQuery queryWithClassName:#"ServiceCatalogue"];
items = [[NSMutableArray alloc] init];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
NSLog(#"ServiceCatalogue retrieved");
} else {
// Log details of the failure
NSLog(#"Error: %# %#", error, [error userInfo]);
}
}];
And getting error:
"Error: Error Domain=NSCocoaErrorDomain Code=3840 "The operation
couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start
with array or object and option to allow fragments not set.)

with array or object and option to allow fragments not set.} {
NSDebugDescription = "JSON text did not start with array or object and option to allow fragments not set.";
}"
As indicated in this status report from Parse, it looks like their servers were creating an elevated number of errors.

I am trying to get Google Maps set up in my iOS application, but am getting a crash on an InvalidArgumentException.
A few people have asked this same question already; however, they have either not gotten helpful responses, or the responses that were given did not solve the problem.
The code is copied directly from Google's Getting Started page:
#import "XXMapViewController.h"
#import <GoogleMaps/GoogleMaps.h>
#interface XXMapViewController ()
#end
#implementation XXMapViewController{
GMSMapView *mapView_;
}
- (void)viewDidLoad
{
[super viewDidLoad];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
longitude:151.20
zoom:6];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
self.view = mapView_;
// Creates a marker in the center of the map.
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
marker.title = #"Sydney";
marker.snippet = #"Australia";
marker.map = mapView_;
// Do any additional setup after loading the view, typically from a nib.
}
#end
This is the line it crashes on, so I have determined it's not a problem with setting the view:
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
And here is the stack trace (app name is X'd out for anonymity's sake):

I have added the -ObjC flag to my project, and have tried adding it to the target as others have recommended; however, adding it to the target causes the build to fail. I created a new single view project as well, which worked fine when following the exact same instructions.I have the correct API key and Google Maps for iOS is enabled in my API console. This has been extraordinarily frustrating and a huge wall in the way of finishing my project. If anybody could point me in the right direction I would greatly appreciate it.
It was a conflict with Parse dependencies. The solution was to either eliminate the FB SDK dependencies or to just download the SDK. I chose the latter since I will inevitably be using it with my app.
