5 i915: Add support for MSI and interrupt mitigation.
6
7 Previous attempts at interrupt mitigation had been foiled by i915_wait_irq's
8 failure to update the sarea seqno value when the status page indicated that
9 the seqno had already been passed. MSI support has been seen to cut CPU
10 costs by up to 40% in some workloads by avoiding other expensive interrupt
11 handlers for frequent graphics interrupts.

5 separate i915 suspend/resume functions into their own file
6
7 [Patch against drm-next. Consider this a trial balloon for our new Linux
8 development model.]
9
10 This is a big chunk of code. Separating it out makes it easier to change
11 without churn on the main i915_drv.c file (and there will be churn as we
12 fix bugs and add things like kernel mode setting). Also makes it easier
13 to share this file with BSD.

5 drm: Rework vblank-wait handling to allow interrupt reduction.
6
7 Previously, drivers supporting vblank interrupt waits would run the interrupt
8 all the time, or all the time that any 3d client was running, preventing the
9 CPU from sleeping for long when the system was otherwise idle. Now, interrupts
10 are disabled any time that no client is waiting on a vblank event. The new
11 method uses vblank counters on the chipsets when the interrupts are turned
12 off, rather than counting interrupts, so that we can continue to present
13 accurate vblank numbers.

7 GEM needs to create shmem files to back buffer objects. Though currently
8 creation of files for objects could have been driven from userland, the
9 modesetting work will require allocation of buffer objects before userland
10 is running, for boot-time message display.

4
5 drm: Add GEM ("graphics execution manager") to i915 driver.
6
7 GEM allows the creation of persistent buffer objects accessible by the
8 graphics device through new ioctls for managing execution of commands on the
9 device. The userland API is almost entirely driver-specific to ensure that
10 any driver building on this model can easily map the interface to individual
11 driver requirements.
12
13 GEM is used by the 2d driver for managing its internal state allocations and
14 will be used for pixmap storage to reduce memory consumption and enable
15 zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable
16 GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

268+ *
269+ * This file provides some of the base ioctls and library routines for
270+ * the graphics memory manager implemented by each device driver.
271+ *
272+ * Because various devices have different requirements in terms of
273+ * synchronization and migration strategies, implementing that is left up to
274+ * the driver, and all that the general API provides should be generic --
275+ * allocating objects, reading/writing data with the cpu, freeing objects.
276+ * Even there, platform-dependent optimizations for reading/writing data with
277+ * the CPU mean we'll likely hook those out to driver-specific calls. However,
278+ * the DRI2 implementation wants to have at least allocate/mmap be generic.
279+ *
280+ * The goal was to have swap-backed object allocation managed through
281+ * struct file. However, file descriptors as handles to a struct file have
282+ * two major failings:
283+ * - Process limits prevent more than 1024 or so being used at a time by
284+ * default.
285+ * - Inability to allocate high fds will aggravate the X Server's select()
286+ * handling, and likely that of many GL client applications as well.
287+ *
288+ * This led to a plan of using our own integer IDs (called handles, following
289+ * DRM terminology) to mimic fds, and implement the fd syscalls we need as
290+ * ioctls. The objects themselves will still include the struct file so
291+ * that we can transition to fds if the required kernel infrastructure shows
292+ * up at a later date, and as our interface with shmfs for memory allocation.

2724+ * clflush is run to get data out of the CPU caches
2725+ * then i915_dev_set_domain calls i915_gem_flush to

2728+ * i915_gem_object_unbind calls set_domain (CPU, CPU)
2729+ * flush_domains and invalidate_domains end up both zero
2730+ * so no flushing/invalidating happens

2759+ * clflush (obj) to invalidate the CPU cache
2760+ * Another MI_FLUSH in i915_gem_flush (eliminate this somehow?)

4537+ *
4538+ * Support for managing tiling state of buffer objects.
4539+ *
4540+ * The idea behind tiling is to increase cache hit rates by rearranging
4541+ * pixel data so that a group of pixel accesses are in the same cacheline.
4542+ * Performance improvement from doing this on the back/depth buffer are on
4543+ * the order of 30%.
4544+ *
4545+ * Intel architectures make this somewhat more complicated, though, by
4546+ * adjustments made to addressing of data when the memory is in interleaved
4547+ * mode (matched pairs of DIMMS) to improve memory bandwidth.
4548+ * For interleaved memory, the CPU sends every sequential 64 bytes
4549+ * to an alternate memory channel so it can get the bandwidth from both.
4550+ *
4551+ * The GPU also rearranges its accesses for increased bandwidth to interleaved
4552+ * memory, and it matches what the CPU does for non-tiled. However, when tiled
4553+ * it does it a little differently, since one walks addresses not just in the
4554+ * X direction but also Y. So, along with alternating channels when bit
4555+ * 6 of the address flips, it also alternates when other bits flip -- Bits 9
4556+ * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines)
4557+ * are common to both the 915 and 965-class hardware.
4558+ *
4559+ * The CPU also sometimes XORs in higher bits as well, to improve
4560+ * bandwidth doing strided access like we do so frequently in graphics. This
4561+ * is called "Channel XOR Randomization" in the MCH documentation. The result
4562+ * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address
4563+ * decode.
4564+ *
4565+ * All of this bit 6 XORing has an effect on our memory management,
4566+ * as we need to make sure that the 3d driver can correctly address object
4567+ * contents.
4568+ *
4569+ * If we don't have interleaved memory, all tiling is safe and no swizzling is
4570+ * required.
4571+ *
4572+ * When bit 17 is XORed in, we simply refuse to tile at all. Bit
4573+ * 17 is not just a page offset, so as we page an objet out and back in,
4574+ * individual pages in it will have different bit 17 addresses, resulting in
4575+ * each 64 bytes being swapped with its neighbor!
4576+ *
4577+ * Otherwise, if interleaved, we have to tell the 3d driver what the address
4578+ * swizzling it needs to do is, since it's writing with the CPU to the pages
4579+ * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the
4580+ * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling
4581+ * required by the CPU of XORing in bit 6, 9, 10, and potentially 11, in order
4582+ * to match what the GPU expects.
4583+ */

5 i915: Use struct_mutex to protect ring in GEM mode.
6
7 In the conversion for GEM, we had stopped using the hardware lock to protect
8 ring usage, since it was all internal to the DRM now. However, some paths
9 weren't converted to using struct_mutex to prevent multiple threads from
10 concurrently working on the ring, in particular between the vblank swap handler
11 and ioctls.

4Subject: [PATCH] fastboot: create a "asynchronous" initlevel
5
6This patch creates an asynchronous initlevel (6a) which is at the same
7level as the normal device initcalls, but with the difference that they
8are run asynchronous from all the other initcalls. The purpose of this
9*selective* level is that we can move long waiting inits that are not
10boot-critical to this level one at a time.
11
12To keep things not totally insane, the asynchronous initcalls are async
13to the other initcalls, but are still ordered to themselves; think of it
14as "bottom-half-not-softirq". This has the benefit that async drivers
15still have stable device ordering between them.

4Subject: [PATCH] fastboot: turn the USB hostcontroller initcalls into async initcalls
5
6the USB host controller init calls take a long time, mostly due to a
7"minimally 100 msec" delay *per port* during initialization.
8These are prime candidates for going in parallel to everything else.
9
10The USB device ordering is not affected by this due to the
11serialized-within-eachother property of async initcalls.

5
6This patch converts a few non-critical ACPI drivers to async initcalls;
7these initcalls (battery, button and thermal) tend to take quite a bit of
8time (100's of milliseconds) due to the hardware they need to talk to,
9but are otherwise clearly non-essential for the boot process.

4Subject: [PATCH] fastboot: hold the BKL over the async init call sequence
5
6Regular init calls are called with the BKL held; make sure
7the async init calls are also called with the BKL held.
8While this reduces parallelism a little, it does provide
9lock-for-lock compatibility. The hit to prallelism isn't too
10bad, most of the init calls are done immediately or actually
11block for their delays.

4Subject: [PATCH] fastboot: sync the async execution before late_initcall and move level 6s (sync) first
5
6Rene Herman points out several cases where it's basically needed to have
7all level 6/6a/6s calls done before the level 7 (late_initcall) code
8runs. This patch adds a sync point in the transition from the 6's to the
97's.
10
11Second, this patch makes sure that level 6s (sync) happens before the
12async code starts, and puts a user in driver/pci in this category that
13needs to happen before device init.

4Subject: [PATCH] fastboot: retry mounting the root fs if we can't find init
5
6currently we wait until all device init is done before trying to mount
7the root fs, and to consequently execute init.
8
9In preparation for relaxing the first delay, this patch adds a retry
10attempt in case /sbin/init is not found. Before retrying, the code
11will wait for all device init to complete.
12
13While this patch by itself doesn't gain boot time yet (it needs follow on
14patches), the alternative already is to panic()...

6The raid autodetect code really needs to have all devices probed before

8where arrays would get detected as degraded while they shouldn't be etc.

10This is in preparation of removing the "wait for everything to init"
11code that makes everyone pay, not just raid users.

4Subject: [PATCH] fastboot: remove "wait for all devices before mounting root" delay
5
6In the non-initrd case, we wait for all devices to finish their
7probing before we try to mount the rootfs.
8In practice, this means that we end up waiting 2 extra seconds for
9the PS/2 mouse probing even though the root holding device has been
10ready since a long time.
11
12The previous two patches in this series made the RAID autodetect code
13do it's own "wait for probing to be done" code, and added
14"wait and retry" functionality in case the root device isn't actually
15available.
16
17These two changes should make it safe to remove the delay itself,
18and this patch does this. On my test laptop, this reduces the boot time
19by 2 seconds (kernel time goes from 3.9 to 1.9 seconds).

4Subject: [PATCH] fastboot: make the RAID autostart code print a message just before waiting
5
6As requested/suggested by Neil Brown: make the raid code print that it's
7about to wait for probing to be done as well as give a suggestion on how
8to disable the probing if the user doesn't use raid.

4Subject: [PATCH] fastboot: remove duplicate unpack_to_rootfs()
5
6we check if initrd is initramfs first and then do real unpack. The
7check isn't required, we can directly do unpack. If initrd isn't
8initramfs, we can remove garbage. In my laptop, this saves 0.1s boot
9time. This penalizes non-initramfs case, but now initramfs is mostly
10widely used.

4Subject: [PATCH] Add a script to visualize the kernel boot process / time
5
6When optimizing the kernel boot time, it's very valuable to visualize
7what is going on at which time. In addition, with the fastboot asynchronous
8initcall level, it's very valuable to see which initcall gets run where
9and when.
10
11This patch adds a script to turn a dmesg into a SVG graph (that can be
12shown with tools such as InkScape, Gimp or Firefox) and a small change
13to the initcall code to print the PID of the thread calling the initcall
14(so that the script can work out the parallelism).

4Subject: [PATCH] fastboot: fix issues and improve output of bootgraph.pl
5
6David Sanders reported some issues with bootgraph.pl's display
7of his sytems bootup; this commit fixes these by scaling the graph
8not from 0 - end time but from the first initcall to the end time;
9the minimum display size etc also now need to scale with this, as does
10the axis display.

606This commit triggers three 'defined but not used' warnings but
607I prefer avoiding to tie these helpers to a specific change in
608the hw start sequences of the 8168 or of the 8101.

1The following patch adds support for Intel's 945GME graphics chip to
2the intelfb driver. I have assumed that the 945GME is identical to the
3already-supported 945GM apart from its PCI IDs; this is based on a quick
4look at the X driver for these chips which seems to treat them
5identically.

11The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
12I'd be able to use it to get a console at the native 1024x600 resolution
13which is not known to the BIOS. I realised too late that the intelfb
14driver does not support mode changing on laptops, so it won't be any
15use for me. But rather than throw it away I will post it here as
16essentially "untested"; maybe someone who knows more about this driver,
17and with more useful hardware to test on, can pick it up.
