Cool.. My first problem is that heavy network transmit loads with messages large enough to use mbuf clusters causes the machine to crash rapidly with some variety of mcl bookkepping problem: Transmit via loopback: # ifconfig lo0 inet 127.0.0.1 up # ./netserver Starting netserver at port 12865 # ./netperf TCP STREAM TEST to localhost Out of mbuf address space! Consider increasing NMBCLUSTERS exclusive sleep mutex Giant r = 0 (0x33b680) locked @ ../../../vm/vm_object.c:446 panic: mb_reclaim() called with locks held Transmit via gem0: # ./netperf -H10.0.0.2 TCP STREAM TEST to 10.0.0.2 panic: m_ext refcnt < 0 However, transmits of non cluster mbufs seem to be fine: # ./netperf -H10.0.0.2 -tUDP_STREAM -- -m 1 UDP UNIDIRECTIONAL SEND TEST to 10.0.0.2 Socket Message Elapsed Messages Size Size Time Okay Errors Throughput bytes bytes secs # # 10^6bits/sec 9216 1 10.01 99419 0 0.08 41600 10.01 99309 0.08 And, recieves seem to be fine on real hardare. To refresh, this is a dual G4 800MHz. Using gem0 (but since it crashes on loopback, I dont' think this is hardware related). What's the status of ddb?

Actually, I think it's a simple problem: the atomic_* routines don't disable interrupts, so there's a window between the initial load and the reservation. I have had problems with this type of thing recently, most notably with the value of td_intr_nesting_level going negative, which I worked around by not re-enabling interrupts in the OpenPIC code. Does this sound plausible to you ? On the bright side, does this also mean that you have built a kernel natively ? I haven't tried that yet :-) later, Peter.

Isn't the lwarx instruction the first instruction in the atomic_* routines? From a brief read of MPCFPE32B.pdf, I thought that the reservation disappeared if the memory convered by the reservation is modified in any way. That's what I'd expect from an atomic op. This reminds me of the load_locked, store_conditional primatives available on alpha..

I haven't tried that yet :-) More or less.. I could compile about 20 files, then the machine would crash. Once I made it through all the .o's, I couldn't get a kernel to link without the machine falling over, so I gave up and used the cross compiler/linker that Mark Peek posted last year..

When linking a kernel, I ran out of mbufs. Probably because the ref counts never dropped to zero on some clusters, so they never got freed.

And it locked up solid the first time I started the build.. After restarting the build as needed, I've built a working kernel natively. Nice work Peter! I've got 2 weird quirks which I was wonder if are specific to my hardware -- - there's no TOY (or TOD) clock read at boot: # uptime 12:02AM up 3 mins, 0 users, load averages: 0.05, 0.06, 0.03 # date Thu Jan 1 00:02:33 GMT 1970 - reboot locks the machine up: # reboot Waiting (max 60 seconds) for system process `vnlru' to stop...stopped Waiting (max 60 seconds) for system process `bufdaemon' to stop...stopped Waiting (max 60 seconds) for system process `syncer' to stop...stopped syncing disks... done Uptime: 21m21s Rebooting... ok 0 At this point, it looks good, but openfirmware won't take any input. Both of these are very minor .. I was just curious.

The only thing I can put it down to is that not enough register context is being restored for the OpenFirmware 'exit' call to work properly. I'll experiment with saving/restoring SPRG0-3, which I noticed NetBSD added recently. later, Peter.

(texto version española/texto version portuguesa). Boletín 1 / Octubre de 2002. LA SOCIEDAD DIGITAL - PORTAL IBEROAMERICANO DE LA SOCIEDAD DE LA INFORMACIÓN. http://www.sociedaddigital.org PRESENTACION: La Sociedad Digital se ha constituido en el principal Portal de la Sociedad de la Información en Ibero América, comprendiendo en la actualidad cerca de quince secciones con un total de documentos estimable en aproximadamente 800, que cubren las áreas más importantes de la Sociedad de la Información. Ello ha sido posible gracias al aporte y la preocupación de un conjunto de especialistas de uno y otro lado del Atlántico, concentrados en este proyecto abierto que comenzó a ser construido en su expresión virtual en octubre de 2001. En la actualidad, la mayor parte de las secciones del Portal se encuentran operativas. El proyecto se viene desarrollando de conformidad con las coordenadas propias de su primera fase: constitución ordenada de un reservorio de información actualizada de elevadas trascendencia para la comprensión de la sociedad en Red conjuntamente con aportes propios producto de investigación colectiva por parte de los equipos de La Sociedad Digital o de aportes individuales de los miembros de su Board de Directores, en el marco de sus respectivas especialidades. ---------------------------------------------------------------------- --------- ESTRUCTURA: Las actuales secciones disponibles del Proyecto Portal de la Sociedad de la Información http://www.sociedaddigital.org son las siguientes: ---------------------------------------------------------------------- -------- NOVEDADES: Las incorporaciones documentales más recientes en el Portal: ---------------------------------------------------------------------- -------- EVENTOS CIENTÍFICOS A DESTACAR: ---------------------------------------------------------------------- ------- INFORMACIONES DEL BOARD: ---------------------------------------------------------------------- ------ PROYECTOS EN DESARROLLO: En este momento, La Sociedad Digital se encuentra desarrollando varios proyectos nuevos, los que se encuentran en diferentes etapas de progreso. En síntesis: (a) Los aspectos operativos: el Portal se encuentra en remodelación, para una presentación en el futuro que pueda considerarse más amigable en su relación con el usuario, y que permitirá un despliegue de mayor agilidad de su contenido documental, así como la correlación temática de sus contenidos. (b) El sistema estadístico: dentro de los proyectos de investigación oportunamente planteados se diseñó un completo sistema estadístico que pudiera ser considerado como uno de los más completos del mundo, reuniendo y conciliando información de al menos veinte fuentes confiables de información, para permitir conocer los principales indicadores de la Sociedad de la Información, al menos en tres grandes niveles de desagregación: contexto mundial, contexto continental y situación de los países. Los indicadores mencionados comprenden accesibilidad, desarrollo de telecomunicaciones, infraestructura de Internet, comercio electrónico, lenguajes en la Red e indicadores representativos de ciencia y tecnología. El trabajo continúa y se estima que estará disponible "en red" en aproximadamente dos meses. (c) Estudio del estado de la Sociedad de la Información en América Latina: este proyecto de investigación, de naturaleza colectiva y abierta, ha culminado su fase de diseño y de términos de referencia. En el decurso del mes de junio comenzará a ser operativo, y se espera llegar con un diagnóstico adecuado hacia fines del presente año y convertirlo en un aporte independiente y trascendente para ser presentado en la Cumbre de la Sociedad de la Información en Junio de 2003. Informaciones y contribuciones en info sociedaddigital.org (d) Colección de estudios e información sobre aspectos prácticos del comercio electrónico: se constituirá en una de las secciones del Portal, considerada de alta utilidad. Se continúa trabajando en la clasificación de la biblioteca virtual aportada por el Consejero Hugo Gallegos de Perú y la sección se encontrará "en Red" en aproximadamente veinte días. --------------------------------------------------------------------- ---------- Usted recibe este mensaje porque su dirección de correo electrónico está incluida dentro de las más de 100.000 que conforman LA SOCIEDAD DIGITAL, construida por referencias o bien por la relevancia de su trabajo, comunidad científica donde se discuten ideas, visiones, experiencias, prácticas e información sobre temas relacionados con La Sociedad de la Información, en especial en Ibero América, impulsada por la Asociación Civil sin fines de lucro La Sociedad Digital.

LA SOCIEDAD DIGITAL - PORTAL IBERO-AMERICANO DA SOCIEDADE DE INFORMAÇÃO www.sociedaddigital.org APRESENTAÇÃO La Sociedad Digital tem se constituído no principal portal da sociedade de informação da região ibero-americana, compreendendo, na atualidade, cerca de quinze seções com um total de documentos estimado em aproximadamente 800, que abordam as áreas mais importantes da sociedade da informação. Isto tem sido possível graças ao aporte e preocupação de um conjunto de especialistas dos dois lados do Atlântico, que se concentraram neste projeto aberto, cuja constituição, em sua expressão virtual, iniciou-se em outubro de 2001. No momento, a maior parte das seções do portal se encontra em funcionamento. O projeto vem se aperfeiçoando na seqüência das mesmas coordenadas estabelecidas em sua primeira fase: constituição ordenada de um reservatório de informações atualizadas e de elevada transcendência para a compreensão da sociedade da Rede, conjuntamente com as contribuições das equipes de La Sociedad Digital, produto da investigação coletiva, bem como outros aportes individuais dos membros de seu corpo de conselheiros, em suas respectivas especialidades. O Projeto Portal da Sociedade da Informação e suas seções disponíveis no endereço www.sociedaddigital.org ---------------------------------------------------------------------- ------ PROJETOS EM DESENVOLVIMENTO: Neste momento, La Sociedad Digital encontra-se desenvolvendo vários projetos novos, os quais se encontram em diferentes fases. Em síntese: (a) Aspectos operativos: o Portal se encontra em reformulação para uma apresentação futura mais amigável em sua relação com o usuário, com um desdobramento mais ágil de seus documentos e da correlação temática de seus conteúdos. (b) Sistema estatístico: dentro dos projetos de investigação a serem oportunamente implantados, elaborou-se um sistema estatístico que pudesse ser considerado como um dos mais completos do mundo, reunindo e conciliando informações extraídas de, pelo menos, vinte fontes confiáveis de informação, ao menos em três grandes níveis de desagregação: contexto mundial, contexto continental e situação dos países.
