| | | | | | | | | | | | | | CFLAGS having '-g' in it, clang outputs several assembly directives that are too new for our version of binutils. Therefore, assemble the resulting .s files with clang instead. A more general solution can be implemented when a GNU as-compatible driver for clang's integrated assembler appears.

* Since r219452 the alignment of __dmadat has changed, revealing that fsread()Marius Strobl2011-07-111-31/+35
| | | | | | | | | | | | | bogusly casts its contents around causing alignment faults on sparc64 and most likely also on at least powerpc. Fix this by copying the contents bytewise instead as partly already done here. Solving this the right way costs some space, i.e. 148 bytes with GCC and 16 bytes with clang on x86 there are still some bytes left there though, and an acceptable hack which tricks the compiler into only using a 2-byte alignment instead of the native one when accessing the contents turned out to even take up more space that.

* - For Cheetah- and Zeus-class CPUs don't flush all unlocked entries fromMarius Strobl2011-07-021-25/+63
| | | | | | | | | | | | | | | | | | | | | | 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.

* The recent change to increase the zfsboot size to 64k made a few BIOSesJohn Baldwin2011-06-231-62/+63
| | | | | | | | | | | | | | | | | | | | | | | | | unhappy (probably they don't handle crossing the 64k boundary, etc.). Fix this by changing zfsldr to use a loop reading from the disk one sector at a time. To avoid trashing the saved copy of the MBR which is used for disk I/O, read zfsboot2 at address 0x9000. This has the advantage that BTX no longer needs to be relocated as it is read into the correct location. However, the loop to relocate zfsboot2.bin can now cross a 64k boundary, so change it to use relative segments instead. (This will need further work if zfsboot2.bin ever exceeds 64k.) While here, stop storing a relocated copy of zfsldr at 0x700. This was only used by the xread hack which has recently been removed (and even that use was dubious). Also, include the BIOS error code as hex when reporting read errors to aid in debugging. Much thanks to Henri Hennebert for patiently testing various iterations of the patch as well as fixing the zfsboot2.bin relocation to use relative segments.

Use the new arch_loadseg I/F to keep track of kernel text and data so that we can wire as much of it as is possible. It is the responsibility of the kernel to link critical (read IVT related) code and data at the front of the respective segment so that it's covered by TRs before the kernel has a chance to add more translations. Use a better way of determining whether we're loading a legacy kernel or not. We can't check for the presence of the PBVM page table, because we may have unloaded that kernel and loaded an older (legacy) kernel after that. Simply use the latest load address for it.

* Add 2 new archsw interfaces:Marcel Moolenaar2011-04-035-30/+55
| | | | | | | | | | | | | | | | | 1. arch_loadaddr - used by platform code to adjust the address at which the object gets loaded. Implement PC98 using this new interface instead of using conditional compilation. For ELF objects the ELF header is passed as the data pointer. For raw files it's the filename. Note that ELF objects are first considered as raw files. 2. arch_loadseg - used by platform code to keep track of actual segments, so that (instruction) caches can be flushed or translations can be created. Both the ELF header as well as the program header are passed to allow platform code to treat the kernel proper differently from any additional modules and to have all the relevant details of the loaded segment (e.g. protection).

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Pre-Boot Virtual Memory (PBVM) to the loader. PBVM allows us to link the kernel at a fixed virtual address without having to make any assumptions about the physical memory layout. On the SGI Altix 350 for example, there's no usuable physical memory below 192GB. Also, the PBVM allows us to control better where we're going to physically load the kernel and its modules so that we can make sure we load the kernel in memory that's close to the BSP. The PBVM is managed by a simple page table. The minimum size of the page table is 4KB (EFI page size) and the maximum is currently set to 1MB. A page in the PBVM is 64KB, as that's the maximum alignment one can specify in a linker script. The bottom line is that PBVM is between 64KB and 8GB in size. The loader maps the PBVM page table at a fixed virtual address and using a single translations. The PBVM itself is also mapped using a single translation for a maximum of 32MB. While here, increase the heap in the EFI loader from 512KB to 2MB and set the stage for supporting relocatable modules. Notes: svn path=/head/; revision=219691
