Many platform support this feature, and it can provide significant power savings when the reduced refresh rate is low. However, on some platforms a secondary (reduced) timing is provided but not actually supported by the hardware. This results in undesirable flicker at runtime. So disable the feature by default, but allow users to opt-in to the reduced clock behavior with a new module parameter, lvds_downclock, that can be set to 1 to enable the feature.

When we setup buffer for display plane, we'll check any pending required GPU flush and possible make interruptible wait for flush complete. But that wait would be most possibly to fail in case of signals received for X process, which will then fail modeset process and put display engine in unconsistent state. The result could be blank screen or CPU hang, and DDX driver would always turn on outputs DPMS after whatever modeset fails or not. So this one creates new helper for setup display plane buffer, and when needing flush using uninterruptible wait for that. This one should fix bug like https://bugs.freedesktop.org/show_bug.cgi?id=24009. Also fixing mode switch stress test on Ironlake.

For some SDVO cards based on conexant chip, we can't read the EDID if we don't read the response after issuing SDVO DDC bus switch command. From the SDVO spec once when another I2C transaction is finished after completing the I2C transaction of issuing the bus switch command, it will be switched back to the SDVO internal state again. So we can't initiate a new I2C transaction to read the response after issuing the DDC bus switch command. Instead we should issue DDC bus switch command and read the response in the same I2C transaction. https://bugs.freedesktop.org/show_bug.cgi?id=23842 https://bugs.freedesktop.org/show_bug.cgi?id=24458 https://bugs.freedesktop.org/show_bug.cgi?id=24522 https://bugs.freedesktop.org/show_bug.cgi?id=24282Signed-off-by: NZhao Yakui <yakui.zhao@intel.com> Tested-by: NSebastien Caty <sebastien.caty@mrnf.gouv.qc.ca> Signed-off-by: NEric Anholt <eric@anholt.net>

For any given clock we can use the find_pll to get the corresponding DPLL setting. It is unnecessary to use the find_reduce_pll callback function to calculate the DPLL parameter for LVDS downclock in order to get the same divider factor(P) for the normal and downclock. In theory when the LVDS downclock is supported by LVDS panel, we should get the same DPLL divider factor(P) for the normal clock and reduced downclock. If we get the diferent divider factor(P) for normal clock and reduced downclock, it means that the found downclock is incorrect and should be discarded. So we should use find_pll callback to calculate the DPLL parameter for the LVDS reduced downclock as for the normal clock. Then we can do the cleanup about find_reduced_pll.

The MMU code uses the copy_*_user_page() variants in access_process_vm() rather than copy_*_user() as the former includes an icache flush. This is important when doing things like setting software breakpoints with gdb. So switch the NOMMU code over to do the same. This patch makes the reasonable assumption that copy_from_user_page() won't fail - which is probably fine, as we've checked the VMA from which we're copying is usable, and the copy is not allowed to cross VMAs. The one case where it might go wrong is if the VMA is a device rather than RAM, and that device returns an error which - in which case rubbish will be returned rather than EIO.

由 Mike Frysinger 提交于
When working with FDPIC, there are many shared mappings of read-only code regions between applications (the C library, applet packages like busybox, etc.), but the current do_mmap_pgoff() function will issue an icache flush whenever a VMA is added to an MM instead of only doing it when the map is initially created. The flush can instead be done when a region is first mmapped PROT_EXEC. Note that we may not rely on the first mapping of a region being executable - it's possible for it to be PROT_READ only, so we have to remember whether we've flushed the region or not, and then flush the entire region when a bit of it is made executable. However, this also affects the brk area. That will no longer be executable. We can mprotect() it to PROT_EXEC on MPU-mode kernels, but for NOMMU mode kernels, when it increases the brk allocation, making sys_brk() flush the extra from the icache should suffice. The brk area probably isn't used by NOMMU programs since the brk area can only use up the leavings from the stack allocation, where the stack allocation is larger than requested.

The current code will load the stack size and protection markings, but then only use the markings in the MMU code path. The NOMMU code path always passes PROT_EXEC to the mmap() call. While this doesn't matter to most people whilst the code is running, it will cause a pointless icache flush when starting every FDPIC application. Typically this icache flush will be of a region on the order of 128KB in size, or may be the entire icache, depending on the facilities available on the CPU. In the case where the arch default behaviour seems to be desired (EXSTACK_DEFAULT), we probe VM_STACK_FLAGS for VM_EXEC to determine whether we should be setting PROT_EXEC or not. For arches that support an MPU (Memory Protection Unit - an MMU without the virtual mapping capability), setting PROT_EXEC or not will make an important difference. It should be noted that this change also affects the executability of the brk region, since ELF-FDPIC has that share with the stack. However, this is probably irrelevant as NOMMU programs aren't likely to use the brk region, preferring instead allocation via mmap().

-
由 Xiaotian Feng 提交于
There're some warnings of "nfsd: peername failed (err 107)!" socket error -107 means Transport endpoint is not connected. This warning message was outputed by svc_tcp_accept() [net/sunrpc/svcsock.c], when kernel_getpeername returns -107. This means socket might be CLOSED. And svc_tcp_accept was called by svc_recv() [net/sunrpc/svc_xprt.c] if (test_bit(XPT_LISTENER, &xprt->xpt_flags)) { <snip> newxpt = xprt->xpt_ops->xpo_accept(xprt); <snip> So this might happen when xprt->xpt_flags has both XPT_LISTENER and XPT_CLOSE. Let's take a look at commit b0401d72, this commit has moved the close processing after do recvfrom method, but this commit also introduces this warnings, if the xpt_flags has both XPT_LISTENER and XPT_CLOSED, we should close it, not accpet then close.
