* Add some more O2Micro devices I gleened from the web site/linux pcmcia cs.Warner Losh2001-04-182-4/+13
| | | | | | | | | | | | Add TI4451 as well. These are untested since I don't have the hardware to test against. Also, some O2Micro devices are #define w/o numbers as place holders so that I can encourage people to submit them when they appear in the channels. Notes: svn path=/head/; revision=75645

Add support for the RL5C466 while I'm at it. Treat TI1031 the same as the CLPD6832. It doesn't work yet, but sucks less than it did before. Also add a few #defines for other changes in the pipe.

* Fix an old bug related to BETTER_CLOCK. Call forward_*clock if SMPJohn Baldwin2001-04-171-3/+3
| | | | | | | | | | | | and __i386__ are defined rather than if SMP and BETTER_CLOCK are defined. The removal of BETTER_CLOCK would have broken this except that kern_clock.c doesn't include <machine/smptests.h>, so it doesn't see the definition of BETTER_CLOCK, and forward_*clock aren't called, even on 4.x. This seems to fix the problem where a n-way SMP system would see 100 * n clk interrupts and 128 * n rtc interrupts. Notes: svn path=/head/; revision=75616

This work was done jointly by jhb and myself, and builds on dfr's earlier work. smp_init_secondary() / smp_start_secondary() - use the uniq val to pass the globalp (me) - fancy footwork to take any pending machine checks (me) - doing things the FreeBSD way and getting the per-cpu idleproc created correctly, and synchronizing the startup of secondaries (jhb) mp_start() - better recognition of available cpus (jhb) smp_rendezvous() - if smp hasn't started, only run the rendezvous function on the current cpu.

* Changes to support SMP:Andrew Gallatin2001-04-171-6/+2
| | | | | | | | | | | | - don't do the stack overflow sanity check on MP systems -- p->p_addr will be malloc'ed memory (not K0SEG) and the check will fail. - don't ignore clock interrupts on secondaries. Alphas apparently roundrobin clock interrupts to all cpus, so we're going to take clock interrupts on all CPUS and not forward them. Notes: svn path=/head/; revision=75600
* changes to smp_init_secondary_glue():Andrew Gallatin2001-04-171-19/+11
| | | | | | | | | | | | | | | - use the unique value to save the per-cpu globalp struct like the comment says - don't lower the ipl to ALPHA_PSL_IPL_HIGH: we may have a pending machine check to take and we're not prepared for that yet, as we haven't setup our interrupt entry points. (this may only happen on sable/lynx) - indicate the fact that the working version of smp_init_secondary() doesn't return (this is tied up in other changes and hasn't yet been committed).

* This patch removes the VOP_BWRITE() vector.Poul-Henning Kamp2001-04-1719-66/+74
| | | | | | | | | | | | | | | | VOP_BWRITE() was a hack which made it possible for NFS client side to use struct buf with non-bio backing. This patch takes a more general approach and adds a bp->b_op vector where more methods can be added. The success of this patch depends on bp->b_op being initialized all relevant places for some value of "relevant" which is not easy to determine. For now the buffers have grown a b_magic element which will make such issues a tiny bit easier to debug. Notes: svn path=/head/; revision=75580
* Add debugging option to always read/write cylinder groups as fullKirk McKusick2001-04-172-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sized blocks. To enable this option, use: `sysctl -w debug.bigcgs=1'. Add debugging option to disable background writes of cylinder groups. To enable this option, use: `sysctl -w debug.dobkgrdwrite=0'. These debugging options should be tried on systems that are panicing with corrupted cylinder group maps to see if it makes the problem go away. The set of panics in question are: ffs_clusteralloc: map mismatch ffs_nodealloccg: map corrupted ffs_nodealloccg: block not in map ffs_alloccg: map corrupted ffs_alloccg: block not in map ffs_alloccgblk: cyl groups corrupted ffs_alloccgblk: can't find blk in cyl ffs_checkblk: partially free fragment The following panics are less likely to be related to this problem, but might be helped by these debugging options: ffs_valloc: dup alloc ffs_blkfree: freeing free block ffs_blkfree: freeing free frag ffs_vfree: freeing free inode If you try these options, please report whether they helped reduce your bitmap corruption panics to Kirk McKusick at <mckusick@mckusick.com> and to Matt Dillon <dillon@earth.backplane.com>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ACL_USER_OBJ and ACL_GROUP_OBJ fields, believing that modification of the access ACL could be used by privileged processes to change file/directory ownership. In fact, this is incorrect; ACL_*_OBJ (+ ACL_MASK and ACL_OTHER) should have undefined ae_id fields; this commit attempts to correct that misunderstanding. o Modify arguments to vaccess_acl_posix1e() to accept the uid and gid associated with the vnode, as those can no longer be extracted from the ACL passed as an argument. Perform all comparisons against the passed arguments. This actually has the effect of simplifying a number of components of this call, as well as reducing the indent level, but now seperates handling of ACL_GROUP_OBJ from ACL_GROUP. o Modify acl_posix1e_check() to return EINVAL if the ae_id field of any of the ACL_{USER_OBJ,GROUP_OBJ,MASK,OTHER} entries is a value other than ACL_UNDEFINED_ID. As a temporary work-around to allow clean upgrades, set the ae_id field to ACL_UNDEFINED_ID before each check so that this cannot cause a failure in the short term (this work-around will be removed when the userland libraries and utilities are updated to take this change into account). o Modify ufs_sync_acl_from_inode() so that it forces ACL_{USER_OBJ,GROUP_OBJ,MASK,OTHER} ae_id fields to ACL_UNDEFINED_ID when synchronizing the ACL from the inode. o Modify ufs_sync_inode_from_acl to not propagate uid and gid information to the inode from the ACL during ACL update. Also modify the masking of permission bits that may be set from ALLPERMS to (S_IRWXU|S_IRWXG|S_IRWXO), as ACLs currently do not carry none-ACCESSPERMS (S_ISUID, S_ISGID, S_ISTXT). o Modify ufs_getacl() so that when it emulates an access ACL from the inode, it initializes the ae_id fields to ACL_UNDEFINED_ID. o Clean up ufs_setacl() substantially since it is no longer possible to perform chown/chgrp operations using vop_setacl(), so all the access control for that can be eliminated. o Modify ufs_access() so that it passes owner uid and gid information into vaccess_acl_posix1e().

* - Fix memory barriers in atomic operations so that the barriers are alwaysJohn Baldwin2001-04-171-20/+26
| | | | | | | | | | | | | | | | "inside" of locked regions. That is, an acquire atomic operation will always enforce a memory barrier after the atomic operation and a release operation will always enforce a memory barrier before the atomic operation. - Explicitly use 'mb' instead of 'wmb' in release atomic operations. The 'wmb' memory barrier is not strong enough to guarantee coherence with other processors. This is effectively a nop since alpha_wmb() actually performs a 'mb' and not a 'wmb', but I wanted the code to be more correct since at some point in the future alpha_wmb()'s implementation may switch to being a real 'wmb'.

| | | | | | | | | | | | | | | we should call ast(). This allows us to branch to a separate Lkernelret label so we can fixup the saved t7 register in the trapframe. Otherwise we can run into a problem on SMP systems where a process is interrupted by a trap or interrupt on one CPU, migrates to another CPU, and then returns with the t7 in the stack clobbering the CPU's t7. As a result, two CPU's would both point to the same per-CPU data and things would go downhill from there. Sleuthing help by: gallatin Notes: svn path=/head/; revision=75562
