the moment, this can only load very simple modules due to missing
symbols. It is being add at this time to make pullups to the
netbsd-7 branch easier. It is not enabled by default in any kernels.
That excludes powerpc because evppc OEA is missing definitions for
PPC_INTR_IMPL and PPC_PCI_MACHDEP_IMPL.
Adjust set lists.
Compile tested for most arches only.
Turns out genfb_softc must be at the start of its own device_private,
so we can't have it in the middle of a structure, and certainly can't
have potentially multiple genfbs per graphics device. Failing to do
this is why entering ddb didn't work with an i915drmkms console.
Instead of putting a genfb_softc into each drm_fb_helper, put a
device_t into each drm_fb_helper and create a new intelfb(4) device
for each Intel framebuffer. This will be more flexible, too, in case
we want accelerated framebuffers later on. (XXX Need to adapt the
radeon code, which I'm disabling until that happens to avoid breaking
the build.)
While here, defer disabling VGA, vga_cndetach, and genfb_attach until
we're actually ready to do them all together along with the mode
switch. This should reduce the amount of time during which the
screen is blanked, in case it hangs.
- Separate the tracking interface from the storage (state table)
and thus prepare to use a new data structure for the storage.
- Fix some race conditions in NAT association logic.
* using kmem_intr on lua_alloc
* using mutex directly on klua_lock
* added ipl arg on klua_newstate()
* added kluaL_newstate function
* fixed synchronization: locking the Lua state on luaioctl
Trying to make do with Linux's page allocation interface is pretty
much always wrong: either we let uvm allocate pages in uvm objects
for us, or we use bus_dma.
Screen blanks on boot on the Ivy Bridge system with
DRM error in cpt_serr_int_handler: PCH transcoder A FIFO underrun
But after that everything is OK. Appears to be an upstream problem.
To investigate...
I think there's a cache flushing issue somewhere -- there are little
display artefacts on my T60.
- vcache_get() retrieves a referenced and initialised vnode / fs node pair.
- vcache_remove() removes a vnode / fs node pair from the cache.
On cache miss vcache_get() calls new vfs operation vfs_loadvnode() to
initialise a vnode / fs node pair. This call is guaranteed exclusive,
no other thread will try to load this vnode / fs node pair.
Convert ufs/ext2fs, ufs/ffs and ufs/mfs to use this interface.
Remove now unused ufs/ufs_ihash
Discussed on tech-kern.
