Initial commit of the new bootloader to support ELF kernel.
...
It consists of two programs named boot_ufs and boot; the former reads
the latter (an OMAGIC a.out).
Boot now utilizes the libsa library to read the actual kernel.
- LFS code exists, but probobly does not work.
- Currently the ELF toolchain is required.
- Many features are missing.

eca_init_rx_hard() shouldn't call eca_init_rx_soft(). That's the

whole point.
2001-09-22 15:33:53 +00:00
cddb5108f8
More re-arrangements: Split eca_init_rx() into two parts, one of which
...
(eca_init_rx_soft()) just sets up software state, and the other of
which (eca_init_rx_hard()) actually puts the interface into receive
mode and sets up the FIQ handler etc. Arrange that when we transmit a
frame, eca_init_rx_soft() has already been called, so we only need to
call eca_init_rx_hard() from the Tx downgrade handler.
The point of this is that I should be able to incorporate the
functionality of eca_init_rx_hard() into the Tx FIQ handler so that we
can switch from Tx to Rx with little enough delay that we don't drop
the first few bytes of the incoming frame.

Re-organise eca(4)'s FIQ handlers. Now we have a single FIQ handler copied
...
to zero page, and it branches to either the rx or tx handler. My intention
is that the tx handler should switch to the rx one the moment it finishes,
without needing a downgrade, which I hope will get rid of the start-of-frame
rx overruns I'm seeing.
While I'm here, move the constants describing the shape of the FIQ state
structures out of if_ecavar.h and into genassym.cf where they belong.

a whole bunch of changes to improve performance and robustness under load:
...
- remove special treatment of pager_map mappings in pmaps. this is
required now, since I've removed the globals that expose the address range.
pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
no longer any need to special-case it.
- eliminate struct uvm_vnode by moving its fields into struct vnode.
- rewrite the pageout path. the pager is now responsible for handling the
high-level requests instead of only getting control after a bunch of work
has already been done on its behalf. this will allow us to UBCify LFS,
which needs tighter control over its pages than other filesystems do.
writing a page to disk no longer requires making it read-only, which
allows us to write wired pages without causing all kinds of havoc.
- use a new PG_PAGEOUT flag to indicate that a page should be freed
on behalf of the pagedaemon when it's unlocked. this flag is very similar
to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
pageout fails due to eg. an indirect-block buffer being locked.
this allows us to remove the "version" field from struct vm_page,
and together with shrinking "loan_count" from 32 bits to 16,
struct vm_page is now 4 bytes smaller.
- no longer use PG_RELEASED for swap-backed pages. if the page is busy
because it's being paged out, we can't release the swap slot to be
reallocated until that write is complete, but unlike with vnodes we
don't keep a count of in-progress writes so there's no good way to
know when the write is done. instead, when we need to free a busy
swap-backed page, just sleep until we can get it busy ourselves.
- implement a fast-path for extending writes which allows us to avoid
zeroing new pages. this substantially reduces cpu usage.
- encapsulate the data used by the genfs code in a struct genfs_node,
which must be the first element of the filesystem-specific vnode data
for filesystems which use genfs_{get,put}pages().
- eliminate many of the UVM pagerops, since they aren't needed anymore
now that the pager "put" operation is a higher-level operation.
- enhance the genfs code to allow NFS to use the genfs_{get,put}pages
instead of a modified copy.
- clean up struct vnode by removing all the fields that used to be used by
the vfs_cluster.c code (which we don't use anymore with UBC).
- remove kmem_object and mb_object since they were useless.
instead of allocating pages to these objects, we now just allocate
pages with no object. such pages are mapped in the kernel until they
are freed, so we can use the mapping to find the page to free it.
this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Change all instances of "[e]isa* at foo?" to "[e]isa0 at foo?".
...
This prevents attaching multiple [E]ISA buses, which we don't support
(Is there any such thing to support? I'm skeptical) and avoids the
"panic: isaattach: ISA bus already seen" that occurs on some laptops
with docking stations and EISA boxes. Since there is only one [E]ISA bus,
logically, the ISA device probe will still find devices on the
docking station.
This does not address the problem of inserting or removing the docking station
at runtime.
