* Overhaul the entropy device:Mark Murray2003-11-175-123/+101
| | | | | | | | | | | | | | | | | | | | | o Each source gets its own queue, which is a FIFO, not a ring buffer. The FIFOs are implemented with the sys/queue.h macros. The separation is so that a low entropy/high rate source can't swamp the harvester with low-grade entropy and destroy the reseeds. o Each FIFO is limited to 256 (set as a macro, so adjustable) events queueable. Full FIFOs are ignored by the harvester. This is to prevent memory wastage, and helps to keep the kernel thread CPU usage within reasonable limits. o There is no need to break up the event harvesting into ${burst} sized chunks, so retire that feature. o Break the device away from its roots with the memory device, and allow it to get its major number automagically.

* - Change the i386's sf_buf implementation so that it never allocatesAlan Cox2003-11-172-27/+50
| | | | | | | | | | | | | | | | | | more than one sf_buf for one vm_page. To accomplish this, we add a global hash table mapping vm_pages to sf_bufs and a reference count to each sf_buf. (This is similar to the patches for RELENG_4 at http://www.cs.princeton.edu/~yruan/debox/.) For the uninitiated, an sf_buf is nothing more than a kernel virtual address that is used for temporary virtual-to-physical mappings by sendfile(2) and zero-copy sockets. As such, there is no reason for one vm_page to have several sf_bufs mapping it. In fact, using more than one sf_buf for a single vm_page increases the likelihood that sendfile(2) blocks, hurting throughput. (See http://www.cs.princeton.edu/~yruan/debox/.)

| | | | | | | | | | | | | | | | | | | - This is heavily derived from John Baldwin's apic/pci cleanup on i386. - I have completely rewritten or drastically cleaned up some other parts. (in particular, bootstrap) - This is still a WIP. It seems that there are some highly bogus bioses on nVidia nForce3-150 boards. I can't stress how broken these boards are. I have a workaround in mind, but right now the Asus SK8N is broken. The Gigabyte K8NPro (nVidia based) is also mind-numbingly hosed. - Most of my testing has been with SCHED_ULE. SCHED_4BSD works. - the apic and acpi components are 'standard'. - If you have an nVidia nForce3-150 board, you are stuck with 'device atpic' in addition, because they somehow managed to forget to connect the 8254 timer to the apic, even though its in the same silicon! ARGH! This directly violates the ACPI spec. Notes: svn path=/head/; revision=122849

* Tweaked the siointr1() so that it works better at 921600 bps, especiallyBruce Evans2003-11-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | with multiple ports on a shared interrupt demultiplexed by the puc_intr() handler. siointr1() first read as much input as possible and then checked all possibly-relevant status registers, partly for robustness and partly for historical reasons. This is very bad if it is called for every port sharing an interrupt like puc_intr() does. It can spend too long reading all the input for some ports when the interrupt is for a more urgent event on another, or just too long checking all the status registers when there are lots of ports. The inter-character time is too long for reading all the input even when the interrupt is for a transmitter interrupt on the same port, and at 921600 bps the inter-char time is 10.85 usec and was often exceeded with just 2 ports, leaving the transmitters idle for about 6% of the time. The tweak is to break out of the read loop after reading 1 char if output can be done. This avoids most of the idle transmitter time for 2 active ports at 921600 bps bidirectional on the test system. It also reduces overhead by about 20%. More complete fixes use the programmable tx low watermark on 16950's and reduce overhead by another 65%. Notes: svn path=/head/; revision=122844
