* [CRYPTO] doc: Update api-intro.txtHerbert Xu2008-01-10
| | | | | | | | | | | | | | This patch updates the list of transforms we support and clarifies that the Block Ciphers interface in fact supports all ciphers including stream ciphers. It also removes the obsolete Configuration Notes section and adds the linux-crypto mailing list as the primary bug reporting address. Finally it documents the fact that setkey should only be called from user context. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | virtio: Force use of power-of-two for descriptor ring sizesRusty Russell2007-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | The virtio descriptor rings of size N-1 were nicely set up to be aligned to an N-byte boundary. But as Anthony Liguori points out, the free-running indices used by virtio require that the sizes be a power of 2, otherwise we get problems on wrap (demonstrated with lguest). So we replace the clever "2^n-1" scheme with a simple "align to page boundary" scheme: this means that all virtio rings take at least two pages, but it's safer than guessing cache alignment.

The former is an implementation detail of the L1 cache which can be useful for performance optimisations, the later is the actual size on which the cache control instructions operate, which can be different. For some reason, we had a weird hack reading the right property on powermac and the wrong one on any other 64 bits (32 bits is unaffected as it only uses the cputable for cache block size infos at this stage). This fixes the booting-without-of.txt documentation to mention the right properties, and fixes the 64 bits initialization code to look for the block size first, with a fallback to the line size if the property is missing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device Initiated Power Management, which is defined in SATA 2.5 can be enabled for disks which support it. This patch enables DIPM when the user sets the link power management policy to "min_power". Additionally, libata drivers can define a function (enable_pm) that will perform hardware specific actions to enable whatever power management policy the user set up for Host Initiated Power management (HIPM). This power management policy will be activated after all disks have been enumerated and intialized. Drivers should also define disable_pm, which will turn off link power management, but not change link power management policy.

* | | Revert lguest magic and use hook in head.SRusty Russell2007-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Version 2.07 of the boot protocol uses 0x23C for the hardware_subarch field, that for lguest is "1". This allows us to use the standard boot entry point rather than the "GenuineLguest" string hack. The standard entry point also clears the BSS and copies the boot parameters and commandline for us, saving more code. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

* | | Example launcher handle guests not being ready for inputRusty Russell2007-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently discard console and network input when the guest has no input buffers. This patch changes that, so that we simply stop listening to that fd until the guest refills its input buffers. This is particularly important because hvc_console without interrupts does backoff polling and so often lose characters if we discard. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* | | Update example launcher for virtioRusty Russell2007-10-23
| | | | | | | | | | | | | | | | | | | | | | | | Implements virtio-based console, network and block servers. The block server uses a thread so it's async, which is an improvement over the old synchronous implementation (but a little more complex). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) This allows us to get alot closer to booting bzImages. 2) It means we don't have to know page_offset. 3) The Guest needs to modify the boot pagetables to create the PAGE_OFFSET mapping before jumping to C code. 4) guest_pa() walks the page tables rather than using page_offset. 5) We don't use page_offset to figure out whether to emulate: it was always kinda quesationable, and won't work for instructions done before remapping (bzImage unpacking in particular). 6) We still want the kernel address for tlb flushing: have the initial hypercall give us that, too.
