1.11 |
| 11-Jul-2023 |
riastradh | linux/idr.h: Need <sys/mutex.h> for kmutex_t.
|
1.10 |
| 25-Oct-2022 |
riastradh | branches: 1.10.2; linux/idr.h: Update ida_* API.
|
1.9 |
| 19-Dec-2021 |
riastradh | Teach idr_remove to accept failure.
But teach it to return the data if it succeeds too.
|
1.8 |
| 19-Dec-2021 |
riastradh | Define idr_init_base.
Nothing actually uses this at the moment, because callers already specify the base. Not really sure what the point is!
|
1.7 |
| 27-Aug-2018 |
riastradh | Draft rewrite of idr preload.
Previous idr code assumed every caller would definitely call idr_preload, idr_alloc, idr_preload_end, but some callers skip idr_alloc if an intermediate failure happens first, and would therefore leak idr nodes.
Use a per-lwp single-node cache instead, and print warnings about leakers.
|
1.6 |
| 27-Aug-2018 |
riastradh | Add ida_simple_remove.
Same as ida_remove for us. Linux requires caller to handle locking for ida_remove (so it works with RCU) and ida_simple_remove just uses a global lock where for users that aren't performance-critical. If we ever pserialized idr, we'd have to do the same.
|
1.5 |
| 27-Aug-2018 |
riastradh | Add idr_get_next and idr_for_each_entry.
|
1.4 |
| 27-Aug-2018 |
riastradh | Sort.
|
1.3 |
| 16-Jul-2014 |
riastradh | branches: 1.3.4; 1.3.28; 1.3.30; Make it build and boot on my test machines.
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.
|
1.2 |
| 18-Mar-2014 |
riastradh | branches: 1.2.2; 1.2.4; 1.2.6; Merge riastradh-drm2 to HEAD.
|
1.1 |
| 24-Jul-2013 |
riastradh | branches: 1.1.2; file idr.h was initially added on branch riastradh-drm2.
|
1.1.2.9 |
| 15-Jan-2014 |
riastradh | Convert linux_idr(9) to use spin locks.
idr_for_each is unlocked; caller must exclude modifications.
Eventually this should be rewritten with pserialize and a fancy bitmap algorithm, but this *actually* works for now.
|
1.1.2.8 |
| 15-Jan-2014 |
riastradh | Revert "Rewrite idr to use a dumber algorithm that admits pserialized use."
This reverts commit 3a389a1cb20777fb73575f0514b96265052ac1ea.
I don't know what I was smoking with this; just need to change the rwlock to a spin lock and we'll be good!
|
1.1.2.7 |
| 30-Dec-2013 |
riastradh | Rewrite idr to use a dumber algorithm that admits pserialized use.
drm2 doesn't use them with RCU, but it does use them under spin locks, so an rwlock is not kosher.
This algorithm is super-dumb, but the idr API has changed upstream, and this is not performance-critical, so it's not worth investing time in a better algorithm at the moment.
|
1.1.2.6 |
| 24-Jul-2013 |
riastradh | Use cpp to prefix linux_ to all the idr names.
Now all global symbols drm2.kmod defines begin with linux_ or drm_, making it easier to check whether I've missed anything by running
nm --undefined-only drm2.kmod | awk '$3 ~ /^(drm|linux)_/'
|
1.1.2.5 |
| 24-Jul-2013 |
riastradh | Add idr_for_each to Linux idr abstraction.
|
1.1.2.4 |
| 24-Jul-2013 |
riastradh | Implement idr_replace.
|
1.1.2.3 |
| 24-Jul-2013 |
riastradh | Implement idr_remove_all.
|
1.1.2.2 |
| 24-Jul-2013 |
riastradh | Dumb implementation of a subset of Linux's idr abstraction.
An idr maintains a mapping from integers to data, like file descriptors to struct file pointers.
|
1.1.2.1 |
| 24-Jul-2013 |
riastradh | Add stubs for Linux header files for drm.
|
1.2.6.2 |
| 22-May-2014 |
yamt | sync with head.

sys/rwlock.h: Make this more self-contained for bool.
machine/mutex.h: Sprinkle includes so this can be used by crash(8).
ddb: New `show all tstiles' command. Shows who's waiting for which locks and what the owner is up to.
Include psl.h for ipl_cookie_t if __MUTEX_PRIVATE
sys: Rip <sys/resourcevar.h> out of <uvm/uvm_param.h>.
And thus out of <sys/param.h>, which is exceedingly overused and fragile and delenda est.
Should fix (some) issues with the recent inclusion of machine/lock.h in various machine/mutex.h files.
arm/mutex.h: Need machine/intr.h, machine/lock.h.
For ipl_cookie_t and __cpu_simple_lock_t. evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL.
Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which should really be fixed. opencrypto/cryptodev.h: Fix includes. - Move sys/condvar.h under #ifdef _KERNEL. - Add some other necessary includes and forward declarations. - Sort.
hp300/intr.h: Fix missing includes. linux/idr.h: Need <sys/mutex.h> for kmutex_t. amiga/intr.h: Don't define spl*() functions if !_KERNEL.
This is used by crash(8) now, and what's important is ipl_cookie_t. cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8). cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER.
Probably not necessary but let's be a little more cautious about this.
atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8).
arm/cpu.h: Need sys/param.h for COHERENCY_UNIT.
Nix machine/param.h -- not meant to be used directly, pulled in by sys/param.h.
Move the definition of ipl_cookie_t out of the kernel-only sections, some _KMEMUSER applications need it.
ddb: Cast pointer to uintptr_t first before db_expr_t.
hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
news68k/intr.h: Fix includes. Put some definitions under _KERNEL.
next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
sys/ksem.h: Hack around fstat(8) abuse of _KERNEL.
sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
x68k/intr.h: Put functions under _KERNEL so crash(8) can use this.
Make ipl_cookie_t visible for _KMEMUSER userland applications.
fix editor mishap in previous
Explicitly include <sys/mutex.h> for kmutex_t.
Replace kmutex_t * (which may be undefined here) with struct kmutex *, suggested by Taylor.
hp300/intr.h: Put most of this under #ifdef _KERNEL. Only ipl_cookie_t really needs to be exposed now, for crash(8).
mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). Make inclusion of sys/intr.h explicit for spl*.
fix hppa and vax builds.
machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in sys/types.h. avoids cpu_data.h vs sched.h include order issues.
move the hppa ipl_t typedef with the moved usage of it. machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h.
Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which always comes from sys/types.h. And, really, sys/types.h (or at least sys/stdint.h) is needed for uintN_t and uintptr_t.
ddb: Cast pointer to uintptr_t, then to db_expr_t. Avoids warnings about conversion between pointer and integer of different size on some architectures.
re-fix hppa builds.
this file uses __cpu_simple_lock(), not just the underlying type, so it does need machine/lock.h.
Break cycle by using `struct kmutex *' instead of `kmutex_t *'. sys/sched.h included sys/mutex.h which includes sys/intr.h which includes machine/intr.h which on cats includes arm/footbridge/footbridge_intr.h which includes arm/cpu.h which includes sys/cpu_data.h which includes sys/sched.h
But there was never any real need for sys/mutex.h in sys/sched.h, because it only uses pointers to the opaque struct kmutex. Cycle broken by using `struct kmutex *' instead of pulling in sys/mutex.h for the definition of kmutex_t.
Side effect: This revealed that sys/cpu_data.h needed sys/intr.h (which was pulled in accidentally by sys/mutex.h via sys/sched.h) for SOFTINT_COUNT. Also revealed some other machine/cpu.h header files were missing includes of sys/mutex.h for kmutex_t.
ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t.
explicitly include no longer implicitly included sys/mutex.h.
arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz. Sidesteps namespace collision with `#define bits ...' in net/zlib.c.
complete the previous - there were two calls to find_first_bit() to fix.
arm/xscale: Missed a spot with previous find_first_bit commit.
evbarm/g42xxeb: Fix off-by-one in previous.
The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x), which is equivalent to fls32(x) - 1, not to fls32(x).
Note that fls32 is 1-based and returns 0 for x=0.
