MFC: r251589
- The method introduced as part of r234898 (MFCed to stable/9 in r236076) for not altering the boot path when booting from ZFS turned out to also cause the boot path not being adjusted if booting from CD-ROM with firmware versions that do not employ the "cdrom" alias in that case. So shuffle the code around instead in order to achieve the original intent. Ideally, we shouldn't fiddle with the boot path when booting from UFS on a disk either; unfortunately, there doesn't seem to be an universal way of telling disks and CD-ROMs apart, though. [1] - Use NULL instead of 0 for pointers.

239054: Create the interface to work with various partition tables from the loader(8). The following partition tables are supported: BSD label, GPT, MBR, EBR and VTOC8. 239057: Remove unused variables. 239058: Introduce new API to work with disks from the loader's drivers. It uses new API from the part.c to work with partition tables. 239060: When GPT signature is invalid in the primary GPT header, then try to read backup GPT header. 239066: Add offset field to the i386_devdesc structure to be compatible with disk_devdesc structure. Update biosdisk driver to the new disk API. 239067: Remove unneeded flag. 239068: Teach the ZFS use new partitions API when probing. Note: now ZFS does probe only for partitions with type "freebsd-zfs" and "freebsd". 239070: Add simple test program that uses the partition tables handling code. It is useful to test and debug how boot loader handles partition tables metadata. 239073: Bump USERBOOT_VERSION. 239087: Add to the debug output the offset from the parent partitioning scheme. 239088: Fix start offset calculation for the EBR partitions. 239127: As it turned out, there are some installations, where BSD label contains partitions with type zero. And it has worked. So, allow detect these partitions. 239210: Add more debug messages. 239211: Add another debug message. 239230: Unbreak booting from the true dedicated disks. When we open the disk, check the type of partition table, that has been detected. If this is BSD label, then we assume this is DD mode. 239231: Remove colons from the debug message, device name returned by the disk_fmtdev() already has the colons. 239232: Restore the old behaviour. If requested partition is a BSD slice, but d_partition isn't explicitly set, then try to open BSD label and its first partition. 239243: After r239066, reinitialize v86.ctl and v86.addr for int 13 EDD probing in sys/boot/i386/libi386/biosdisk.c. Otherwise, when DISK_DEBUG is enabled, the DEBUG() macros will clobber those fields, and cause the probing to always fail mysteriously when debugging is enabled. 239292: Explicitly terminate the string after strncpy(3). 239293: Rework r239232 to unbreak ZFS detection on MBR slices. 239294: Some BIOSes return incorrect number of sectors, make checks less strictly, to do not lost some partitions. 239325: Add comment why the code has been disabled. 240272: Make struct uboot_devdesc compatible with struct disk_devdesc. 240273: Use disk_fmtdev() and disk_parsedev() functions from the new DISK API. 240274: Update uboot's disk driver to use new DISK API. 240275: Build disk.c only when DISK_SUPPORT is enabled. 240276: Update according to the change of struct uboot_devdesc. 240277: Handle LOADER_NO_DISK_SUPPORT knob in the arm and powerpc ubldr. 240335: Slightly reduce an overhead for the open() call in the zfsloader. libstand(3) tries to detect file system in the predefined order, but zfsloader usually is used for the booting from ZFS, and there is no need to try detect several file system types for each open() call. 240481: The MBR data is not necessarily aligned. This is a problem on ARM. 241023: Make the loader a bit smarter, when it tries to open disk and the slice number is not exactly specified. When the disk has MBR, also try to read BSD label after ptable_getpart() call. When the disk has GPT, also set d_partition to 255. Mostly, this is how it worked before. 241047: Disable splitfs support, since we aren't support floppies for a long time. This slightly reduces an overhead, when loader tries to open file that doesn't exist. 241053: Almost each time when loader opens a file, this leads to calling disk_open(). Very often this is called several times for one file. This leads to reading partition table metadata for each call. To reduce the number of disk I/O we have a simple block cache, but it is very dumb and more than half of I/O operations related to reading metadata, misses this cache.
Introduce new cache layer to resolve this problem. It is independent and doesn't need initialization like bcache, and will work by default for all loaders which use the new DISK API. A successful disk_open() call to each new disk or partition produces new entry in the cache. Even more, when disk was already open, now opening of any nested partitions does not require reading top level partition table. So, if without this cache, partition table metadata was read around 20-50 times during boot, now it reads only once. This affects the booting from GPT and MBR from the UFS. 241065: Fix disk_cleanup() to work without DISK_DEBUG too. 241068: Reduce the number of attempts to detect proper kld format for the amd64 loader. 241069: Remember the file format of the last loaded module and try to use it for next files. 241070: Fix the style. 241164: Replace all references to loader_callbacks_v1 with loader_callbacks. 241809: Add the flags parameter to the disk_open() function and DISK_F_NOCACHE flag, that disables the caching of partition tables metadata. Use this flag for floppies in the libi386/biosdisk driver. 241876: When loader tries to open GPT partition, but partition table is not GPT, then try automatically detect an appropriate partition type.

Pull the tier-2 card and change the sparc64 ZFS loader to no longer probe all diskN aliases for providers (which more or less corresponds to how the x86 version behaves) but instead probe only those listed in the boot-device OFW environment variable. This has the following advantages: - avoids otherwise unavoidable OFW warnings about failures to open disks for which aliases exist but no actual hardware is connected - avoids issues due to different diskN naming schemes - aligns us with Solaris

- For Cheetah- and Zeus-class CPUs don't flush all unlocked entries from the TLBs in order to get rid of the user mappings but instead traverse them an flush only the latter like we also do for the Spitfire-class. Also flushing the unlocked kernel entries can cause instant faults which when called from within cpu_switch() are handled with the scheduler lock held which in turn can cause timeouts on the acquisition of the lock by other CPUs. This was easily seen with a 16-core V890 but occasionally also happened with 2-way machines. While at it, move the SPARC64-V support code entirely to zeus.c. This causes a little bit of duplication but is less confusing than partially using Cheetah-class bits for these. - For SPARC64-V ensure that 4-Mbyte page entries are stored in the 1024- entry, 2-way set associative TLB. - In {d,i}tlb_get_data_sun4u() turn off the interrupts in order to ensure that ASI_{D,I}TLB_DATA_ACCESS_REG actually are read twice back-to-back.

Partially revert r203829; as it turns out what the PowerPC OFW loader did was incorrect as further down the road cons_probe() calls malloc() so the former can't be called before init_heap() has succeed. Instead just exit to the firmware in case init_heap() fails like OF_init() does when hitting a problem as we're then likely running in a very broken environment where hardly anything can be trusted to work.

Add support for SPARC64 V (and where it already makes sense for other HAL/Fujitsu) CPUs. For the most part this consists of fleshing out the MMU and cache handling, it doesn't add pmap optimizations possible with these CPU, yet, though. With these changes FreeBSD runs stable on Fujitsu Siemens PRIMEPOWER 250 and likely also other models based on SPARC64 V like 450, 650 and 850. Thanks go to Michael Moll for providing access to a PRIMEPOWER 250.

Some machines can not only consist of CPUs running at different speeds but also of different types, f.e. Sun Fire V890 can be equipped with a mix of UltraSPARC IV and IV+ CPUs, requiring different MMU initialization and different workarounds for model specific errata. Therefore move the CPU implementation number from a global variable to the per-CPU data. Functions which are called before the latter is available are passed the implementation number as a parameter now.

Use the SUNW,{d,i}tlb-load methods for entering locked TLB entries like OpenBSD and OpenSolaris do instead of fiddling with the MMUs ourselves. Unlike direct access the firmware methods don't automatically use the next free (?) TLB slot, instead the slot to be used has to be specified. We allocate the TLB slots for the kernel top-down as OpenSolaris suggests that the firmware will always allocate the ones for its own use bottom-up. Besides being simpler, according to OpenBSD using the firmware methods is required to allow booting on Sun Fire E10K with multi-systemboard domains.

- Assert that HEAPSZ is a multiple of PAGE_SIZE as at least the firmware of Sun Fire V1280 doesn't round up the size itself but instead lets claiming of non page-sized amounts of memory fail. - Change parameters and variables related to the TLB slots to unsigned which is more appropriate. - Search the whole OFW device tree instead of only the children of the root nexus device for the BSP as starting with UltraSPARC IV the 'cpu' nodes hang off of from 'cmp' (chip multi-threading processor) or 'core' or combinations thereof. Also in large UltraSPARC III based machines the 'cpu' nodes hang off of 'ssm' (scalable shared memory) nodes which group snooping-coherency domains together instead of directly from the nexus. - Add support for UltraSPARC IV and IV+ BSPs. Due to the fact that these are multi-core each CPU has two Fireplane config registers and thus the module/target ID has to be determined differently so the one specific to a certain core is used. Similarly, starting with UltraSPARC IV the individual cores use a different property in the OFW device tree to indicate the CPU/core ID as it no longer is in coincidence with the shared slot/socket ID. While at it additionally distinguish between CPUs with Fireplane and JBus interconnects as these also use slightly different sizes for the JBus/agent/module/target IDs. - Check the return value of init_heap(). This requires moving it after cons_probe() so we can panic when appropriate. This should be fine as the PowerPC OFW loader uses that order for quite some time now.

USIII and beyond CPUs have stricter requirements when it comes to synchronization needed after stores to internal ASIs in order to make side-effects visible. This mainly requires the MEMBAR #Sync after such stores to be replaced with a FLUSH. We use KERNBASE as the address to FLUSH as it is guaranteed to not trap. Actually, the USII synchronization rules also already require a FLUSH in pretty much all of the cases changed. We're also hitting an additional USIII synchronization rule which requires stores to AA_IMMU_SFSR to be immediately followed by a DONE, FLUSH or RETRY. Doing so triggers a RED state exception though so leave the MEMBAR #Sync. Linux apparently also has gotten away with doing the same for quite some time now, apart from the fact that it's not clear to me why we need to clear the valid bit from the SFSR in the first place.

This is done so that these functions will still mask the debug bits of spitfire-class CPUs once we increase TD_PA_BITS to match the number of bits used for the PA by cheetah-class CPUs. - Change {d,i}tlb_enter_sun4u() to also set TLB_CTX_KERNEL as the context of the mappings entered. This is more or less cosmetic as TLB_CTX_KERNEL is 0. - Now that we have to distinguish between different sun4u CPUs in the loader anyway, no longer do trial and error when reading the portid property.

- Make better use of the global chosen, memory and mmu handles instead of obtaining them over and over again and pretending we could do anything useful without them (for chosen this includes adding a declaration and initializing it in OF_init()). - In OF_init() if obtaining the memory or mmu handle fails just call OF_exit() instead of panic() as the loader hasn't initialized the console at these early stages yet and trying to print out something causes a hang. With OF_exit() one at least has a change to get back to the OFW boot monitor and debug the problem. - Fix OF_call_method() on 64-bit machines (this is a merge of sys/dev/ofw/openfirm.c rev 1.6). - Replace OF_alloc_phys(), OF_claim_virt(), OF_map_phys() and OF_release_phys() in the MI part of the loader with wrappers around OF_call_method() in the sparc64. Beside the fact that they duplicate OF_call_method() the formers should never have been in the MI part of the loader as contrary to the OFW spec they use two-cell physical addresses. - Remove unused functions which are also MD dupes of OF_call_method(). - In sys/boot/sparc64/loader/main.c add __func__ to panic strings as different functions use otherwise identical panic strings and make some of the panic strings a tad more user-friendly instead of just mentioning the name of the function that returned an unexpected result.

Keep track of the ttes used to map the kernel and pass them to it as loader metadata. Modify tlb handling functions to take a tte, instead of virtual address, physical address and flags.

Fix fs support ifdefs. Add tftp support. Add physical and virtual watchpoint support for debugging (under LOADER_DEBUG). Claim the physical and virtual addresses used to map the kernel from the prom; we map it ourselves behind the scenes though. Add a reboot command.
