For now, since we have a mix of bridges which support this flag, which which do *not* support this flag, or work both ways, try it once with NO_CONNECTOR and then fall back to the old way if that doesn't work.

The only usage of hdmi_8996_pll_ops is to assign its address to the ops field in the clk_init_data struct, and the only usage of pll_init is to assign its address to the init field in the clk_hw struct, both which are pointers to const.

The downstream driver models this PLL lock check as an if-elseif-else. The only way to reach the else case where pll_locked=true [1] is by succeeding both readl_poll_timeout_atomic calls (which return zero on success) in the if _and_ elseif condition. Hence both the "lock" and "ready" bit need to be tested in the SM_READY_STATUS register before considering the PLL locked and ready to go. Tested on the Sony Xperia XA2 Ultra (nile-discovery, sdm630).

The return type of ktime_divns() is s64. The timeout_to_jiffies() currently assigns the result of this ktime_divns() to unsigned long, which on 32 bit systems may overflow. Furthermore, the result of this function is sometimes also passed to functions which expect signed long, dma_fence_wait_timeout() is one such example. Fix this by adjusting the type of remaining_jiffies to s64, so we do not suffer overflow there, and return a value limited to range of 0..INT_MAX, which is safe for all usecases of this timeout. The above overflow can be triggered if userspace passes in too large timeout value, larger than INT_MAX / HZ seconds. The kernel detects it and complains about "schedule_timeout: wrong timeout value %lx" and generates a warning backtrace. Note that this fixes commit 6cedb8b3 ("drm/msm: avoid using 'timespec'"), because the previously used timespec_to_jiffies() function returned unsigned long instead of s64: static inline unsigned long timespec_to_jiffies(const struct timespec *value) Fixes: 6cedb8b3 ("drm/msm: avoid using 'timespec'") Signed-off-by:

Currently there is audio not working problem after system resume from suspend if hdmi monitor stay plugged in at DUT. However this problem does not happen at normal operation but at a particular test case. The root cause is DP driver signal audio with connected state at resume which trigger audio trying to setup audio data path through DP main link but failed due to display port is not setup and enabled by upper layer framework yet. This patch only have DP driver signal audio only when DP is in disconnected state so that audio option shows correct state after system resume. DP driver will not signal audio with connected state until display enabled executed by upper layer framework where display port is setup completed and main link is running.

The overflow check does causes a warning from clang-14 when 'sz' is a type that is smaller than size_t: drivers/gpu/drm/msm/msm_gem_submit.c:217:10: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (sz == SIZE_MAX) { Change the type accordingly.

Some userspace apps make assumptions that rendering against multiple contexts within the same process (from the same thread, with appropriate MakeCurrent() calls) provides sufficient synchronization without any external synchronization (ie. glFenceSync()/glWaitSync()). Since a submitqueue maps to a gl/vk context, having multiple sched entities of the same priority only works with implicit sync enabled. To fix this, limit things to a single sched entity per priority level per process. An alternative would be sharing submitqueues between contexts in userspace, but tracking of per-context faults (ie. GL_EXT_robustness) is already done at the submitqueue level, so this is not an option. Signed-off-by: -

msm_file_private is more gpu related, and in the next commit it will need access to other GPU specific #defines. While we're at it, add some comments. Signed-off-by: -

In theory a context can be destroyed and a new one allocated at the same address, making the pointer comparision to detect when we don't need to update the current pagetables invalid. Instead assign a sequence number to each context on creation, and use this for the check. Fixes: 84c31ee1 ("drm/msm/a6xx: Add support for per-instance pagetables") Signed-off-by:

I've seen some crashes in our crash reporting that *look* like multiple threads stomping on each other while communicating with GMU. So wrap all those paths in a lock. Signed-off-by: -

If the device file was opened prior to fw being available (such as from initrd before rootfs is mounted, when the initrd does not contain GPU fw), that would cause a later crash when the dev file is closed due to unitialized submitqueues list: CPU: 4 PID: 263 Comm: plymouthd Tainted: G W 5.15.0-rc2-next-20210924 #2 Hardware name: LENOVO 81JL/LNVNB161216, BIOS 9UCN33WW(V2.06) 06/ 4/2019 pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : msm_submitqueue_close+0x30/0x190 [msm] lr : msm_postclose+0x54/0xf0 [msm] sp : ffff80001074bb80 x29: ffff80001074bb80 x28: ffff03ad80c4db80 x27: ffff03ad80dc5ab0 x26: 0000000000000000 x25: ffff03ad80dc5af8 x24: ffff03ad81e90800 x23: 0000000000000000 x22: ffff03ad81e90800 x21: ffff03ad8b35e788 x20: ffff03ad81e90878 x19: 0000000000000000 x18: 0000000000000000 x17: 0000000000000000 x16: ffffda15f14f7940 x15: 0000000000000000 x14: 0000000000000000 x13: 0000000000000001 x12: 0000000000000040 x11: 0000000000000000 x10: 0000000000000000 x9 : ffffda15cd18ff88 x8 : ffff03ad80c4db80 x7 : 0000000000000228 x6 : 0000000000000000 x5 : 1793a4e807e636bd x4 : ffff03ad80c4db80 x3 : ffff03ad81e90878 x2 : 0000000000000000 x1 : ffff03ad80c4db80 x0 : 0000000000000000 Call trace: msm_submitqueue_close+0x30/0x190 [msm] msm_postclose+0x54/0xf0 [msm] drm_file_free.part.0+0x1cc/0x2e0 [drm] drm_close_helper.isra.0+0x74/0x84 [drm] drm_release+0x78/0x120 [drm] __fput+0x78/0x23c ____fput+0x1c/0x30 task_work_run+0xcc/0x22c do_exit+0x304/0x9f4 do_group_exit+0x44/0xb0 __wake_up_parent+0x0/0x3c invoke_syscall+0x50/0x120 el0_svc_common.constprop.0+0x4c/0xf4 do_el0_svc+0x30/0x9c el0_svc+0x20/0x60 el0t_64_sync_handler+0xe8/0xf0 el0t_64_sync+0x1a0/0x1a4 Code: aa0003f5 a90153f3 f8408eb3 aa1303e0 (f85e8674) ---[ end trace 39b2fa37509a2be2 ]--- Fixing recursive fault but reboot is needed!
