Subject Area
Since NetBSD 5 was released, the support for MIPS on NetBSD has been completely revamped. It is now one of the more advanced ports of NetBSD. This talk is an overview on what has changed and what the current state of MIPS support and a brief look forward to what else is coming. Subjects to be covered: Why? (Big Embedded space, large amounts of memory, etc). Quick Introduction to the MIPS architecture Overview of XLR/XLS/XLP Overview of what changed (toolchain, SMP, pmap, PCU, compat32, new cpu support, use of MIPS features, fast softint) Design decisions why N32 by default? why no separate mips64? Major features 64-bit address space cpu abstraction dynamic fixups (changing indirect calls to direct calls) splsw UVM changes Fast software interrupts SMP (for NetLogic XLR/XLS/XLP) mostly lockless pmap Choosing a new page size COMPAT NETBSD32 networking filesystem mounting 32-bit systems N32 Kernels Effects on the NetBSD in general PCU direct-mapped UAREAs COMPAT NETBSD32 common pmap for TLB based MMUs

and so it all came yet none of the line on doesn't have the part hello everybody characters respect and so out of date there has a great variety of pronunciations of each year and about the case is the following marking on this so it was really funny but and will so
aggressively units offices and you know the DATA prosperous world map that of this and was you have to learn using the word using more light or or in in world what you have to with on you will live in or that candidate there is a lot of this work was announced the I haven't said so it is for those
that the at at the disease with people the resonances of the in the face of the and let law but let both slot and unity but the whole notion that you know and in a square Rio we where hardly any room in of news 1st of the later on in this war and along that in music because the so and thing here and it's all right but has learned it now
the the it is let in here it's the colonies around the and once the I some issue that arises in the cost and no I asked the slow reading I have used the 1st half of the year you know in the world now on record it is only masters of the world it this little read that have or and the all right it's the only rest by I know to have hence the and
this is where the death rate of them all out is listed for sale and that is the only means and you know there is there is a lot of it it was all have you know a bit and I think to give I the this year is more of a feeling that you have it all union and this is all in an of this year this out and say the studies the the sort of related now interaction so this song and his our so on the OS and in so it turns out that year 1 so that is it's worth it and how will you there are the of I this the the reason that the hand love her the case at the program hold on but I believe that was the house of 1 of the easiest forms use these include the memory of the that the long and you have a that's the as long as there was 2 A-Z 1 it carries and now you know as in the wall that was over man but this is only half on your the or all the on the at MIT where we have
as you know and as a whole of in the and as grammar was he's in said you well you know you can score so you know see the user and noted that all and you know all criminal you were were and there you have it you move it on house and and this is where was on that will be in in the have means for the fans the book of a lot you has for it also means that later on we said so the it's only in the eye to a lot of this is more so and they have to live in is what is the best on this house is so those or and solid It's all it is it is and the
and these are all is around all is something that so the the rest of the basically wanted to see work on the on the right the about there's a lot slower if these are then the 1 is the same it an hour or on the on the the the worst or on the other hand analysts the horrible yeah you know you have the answers for things like you all my heart of an error in the heart of and and this is easy and there are a lot on 84 and it is 1 of the the long and it was it was Kristen that is foreign wall rude enough associated with this only in that was there he said you have the rise in the and I also use and in fact what we will in my own hair on his laurels easier and I just said the in the story right now the know of this is where it is
all the only that really and that's important to know you know you know of his the rest you are still in the world that have these years have so it if you and I that much was by all of and how was that you by all of the battles but it is not is and the last 1 of along these lines are
used and he is more you know the passing of all data in the war and all of us in a kernel of sort the the of creation that almost all the answers but I on
my 1st order that is the national unless you have or it can be used I must say and so I have here is the sum all of these in this part model of the elites and thing introduces or half of the the news he said were less you I think mean a little on the along with you you have the you know there are times where you to have a look at all of also that when you're in the wrong and who are also all in the in the policy in the users' in finally what the not
a lot here he spent hours the 1st call is a is a all you want we use it and has the a lesson on the normally the US the Top at Reddy was and elite and the world at a form on the are earlier this year and you work the inflow of the community so that we have a lot what we are in the the and the the beauty said the earlier this year the and you have the solid line of it was looking at the wrong time in the novel on all on his is that all about we are we the more of you in this it certainly so we know the Willard is that you have promised pollen world or in a small is or if you had it all of these reasons and the in all of the sky know it was a or it you know
now the thing is the hours on a you but now is variable is the core of the Lennart School in all had read the right and we were and transferred well for in this room and all of the call and as a source of what we know it the world what that often this is the leader of the not possible or at I read that you have you this members of the you like the cost of all the whole world all around the world has seen the word pain and the thing here are the ones this I mean had in the story was a piece of work around and all these you know I had in the city the whole of the of the that is the is the more or more aware of solving the problem is our our the the set of all of the environment of the world and the use of these and you would write it in hot more or all but there's a lot of that reacquired schools and on the side of the brain of the this patent rights the also and on the and then really programs that we all and this is the 1 where we all know that most of the and produce or
was but it is used center world all of this is the the only and this is the of obviously you want you know all of them so what we're all of the location with the error as well thank you and here we go the and the press on the war I had only the the result and you can also use it is part of my so only you you know this hollow words or the only way that is called all as equation Valerian over the of initially we ran or in the order the and who that they because of that yes it is you need that kind of in the the blue is only half of us I mean is that on the of all all right all right and this is what we have is growing that's so what we have but he had his hands of you that we were made up of our world along the way all and it goes on the new friends who was and or
it was bombed out of all of you 1st all you have the power to set these DNA in the this you know you need in the European or and so on what we have here as well as working on the all the more what that
the the up here what you have honor that was and the other on the back the Mori now that we have as or register with all is at the this best and there with a lot of people that it was in but also on the and I was still while the Willard X is on an these areas of that was all only in front of the other and released or we did this fall format and in the religion and all of this is so from early need and you know all of you have had using the lose I suppose there is always in all room HALL or with the use of all and the sentences in Europe and the world around you is the name and all this out of all or was it will be the area you and all the as these but once we have this kind of all of this is is that at the end at the root of what needs that he all of this is that in this in the colon the the what do you think and you that usually in on the other side there is that the is that you have in that the the see a lot more than on the these are all on the and if you're a loss of people in the result of these you know all the people of the world Collins you have a sense of history for you want you all the kernel the so what and also all over again as the 1st your island all this for assessing the volume and and so will always love to at the bottom 86 and so on how old 1 and and but heard all inclusive has and this that is at grew in the end and all that he also and so those then was love very show up that the following that
its use and the mother of all the matter in the theater all and so I have I hold your was much of a and is like that
always or of of the theory the you all know that the you know as hell on it is only the of know how to back look at the
he calls the all the the and the new Europe on all of that out released day or the you know called the point on have all of them in the you also so can look at it and I hope you will need at a in the 1st hour and you that it did on in his you this is always at the heart of Moline no no the set of all the but you know that and it's all all as and literally reasons for the in the year after that you know you have a you are all aware of the act as once so that of in all the this book and you have higher while there is room around here and the and calls your as you there is a lot of those a long it and
and also the sun at present the findings of in the past not at all the that was the whole idea this time is not so it all editions and it is common as and the this is great you know that of and in you want something you have to know that all that we the theory that mean so you will all a model and it might even on the that and what this app is that and of
you don't of the agent not really isn't have very length it's not ended yeah on the side and so on I
grew up has given up on you know was hardly a day in the use of all alone I haven't it on the of on the 2nd 1 will not be all all you know if all of all the same with the of in the and that and and he or their time it's again at at really the that the Office of the United it is not only that it is not all or in your was it when and you have a source of water I use as you have in you know what you think is that the end of the period of time of the grammar and once you as long as it is the
head of on the side and watch the all very long and to use all the of the as you know but he's of all people in a way that about Us you have you in it his along a little over the course of the said was Laurent it perhaps and that all of the old way you have grown all around the a lot of it's a what is up and so it all of you the law of it that on the and that was and if you look at the where or at the movies or in in the end the whole or the army is that enough the up and all in year only use all at what at the end of the year and what was going on in the year and so of you all right you write this and I was in it has said and so think we knew that his talk you're out a the air on that the other thing is what
and I said have that of the as and you have also from the center of the poor and the what is on the at the of all you have to mark all of you that 11 and so it was on the how can I say on that and as this is law of the lack of is this form and on you if you waited for or the art of the this is 1 of the that not the an adverse effect on you room was not at all the and there the where have that's the in the face of the of the work the requirements a while and I know that there is used to I want and that and in this it of
the it the last thing we have to be was to get by follow us on the years it at he is a lot of its or or long all of all you know the way I think Europe at at the same time as you have to work on that grant at son to Europe off you only by and and is on the and so on and off RCC by that in that human the month mentioned that it is known that is from a really small and that the there only the the US alone and whereas the around the world but in a survey you have called in among them the more of these 2 but many of the head of the the thing that really not that but that gossip or you know you're in luck here and what the are was at you know you know then of the at the time so this the variation of the the to but finally Wireless means that each of the 4 and you know what all what we're always embedded in our that only more and 1 of the the
office button in these areas the word not that you but that that of the universe this in the rare on the 1 you it and right if you have this formula of 1 of you on all of the we might find it in the middle his you all of you I knew that was the on what is hat or the the it is required let's say the I see an and there are because we have not only it means that the about that is that of any and all that kind of and now
he is the whole her also was granted apps on the in her own heard in the the you as you know when you are I know I don't know if this was in it is like were all and you are in the in the in the in the look at me not it can be right age of the the in that you would have
to basically means that you know that but said look at a very early in course on that and in the little or no smaller they that this is a and it the I it was going to work in that it that's all and at 1 you you but also the you know is that see you in the hall the problem is that the you probably that and as on the role the is is the way that it had the graph and earlier in the early in of it's of you know that the past there's a whole of these the is a but if you really and
in the ways what you need to know a lot of Hairer said that you can have it all you think that all men or wrapped up on the NS a bonus
money you you agree with that that indicated that all or none of them all and in the office the result of that in this the long you have to because all of us all many people at all the was back in that all the things of it all to and I the the in such a way that allows users to have prior to the the in this but the morning of the 1 and the world the history of the the this is 1 of the
then the the the you so that you can look at it and you have all of the little a these are all the core of me being and you don't have the and all of is well and the last thing that all really well in the middle of and in in the end you in the EU all you have here and as you saw me the of you will hear it you know and that of course there's if I have a call for a very long but it is so an the same of the and all on the where the we know we like all of now the all and all but he was as a whole what you that the this will be and look at and learned that you all and from this this set of and follow that and from residents is certainly not I think both of these were on the and so on this is 1 of his life right thing as so you know all about it at all the his work really the and it was all of that on the same it can so the flow of all and so on in
a all right the these what that it onset that that of all that the only union also that doesn't work so all that now that you that also in the form is that's what you know or of all is that and so it's like there of the as they roles at all all the and all little and for a long term on and this is the only that where the file and it and some of it all new Pringle school I think
all the work in these of a fire at the that use it and information and that on our and as you know well of the and it the and it is if you have form and
the all always 80 when if you want to work in the offices were the I want you all you were rework this going and out follow so in the I mean all of the all that the so you think there the the in more year open ended loans in these areas of and the little while all the EU and this is where all the of the war all of and that this is all result and it is not really all the world in the in the the Union was you in all of these this about it really is just use all of that this and it was in the course of the you know the rest the here at but also and there but it over to you and so on so that they were on all right there
on the was fired what the the life really you look you that is it was less than a year on the spot on the that while in the those those units have the the fact is that earlier here are some of the the the what and all it Jesus I heard the other Bryant them in a know I think they're all scared of Britain the room of course the the of living 1 the they say and the you can you know there are lots of their use the person that he or the the the what might be bad for you the is that you all of this I have been searching the all this in all in the area at the time of the
