From abf015f04614a3a7da43d35b55edc90189af4e6a Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 7 Nov 2011 19:04:36 +0000 Subject: Revert "ARM: 7098/1: kdump: copy kernel relocation code at the kexec prepare stage" This reverts commit 2b034922af2caa19df86f0c502e76cb6f6e910f9. Will Deacon reports: This is causing kexec to fail. The symptoms are that the .init.text section is not loaded as part of the new kernel image, so when we try to do the SMP/UP fixups we hit a whole sea of poison left there by the previous kernel. So my guess is that machine_kexec_prepare *is* too early for preparing the reboot_code_buffer and, unless anybody has a good reason not to, I'd like to revert the patch causing these problems.

Before v3.1-rc1 the omapdss driver was managing clocks and resets correctly. However, when omapdss started using runtime PM at v3.1-rc1, the responsibility for the reset moved to HWMOD framework. HWMOD framework does not currently enable all the DSS clocks when resetting the DSS hardware. This causes the HWMOD frameworks boot-time reset to fail, possibly leaving the DSS hardware in undefined state. This patch sets HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core. The flag is actually not used on OMAP4, because dss_core hardware does not have soft-reset functionality and thus the HWMOD framework never resets nor waits for the reset to finish. However, while the flag is not strictly needed currently, I think it represents the HW correctly: all the DSS clocks should be enabled after power-on to allow DSS hardware to finish its reset. A custom reset function will be added in the following patches which manages this correctly for OMAP4.

The function doesn't actually do a reset, it only waits for the reset to complete. The reason for this is that on OMAP4 there is no possibility to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets all the other DSS modules also, thus breaking the HWMOD model where every DSS module is handled independently. This fixes the problem with DSS reset on OMAP4, caused by the fact that because there's no SW reset for dss_core on OMAP4, the HWMOD framework doesn't try to reset dss_core and thus the DSS clocks were never enabled at the same time. This causes causes the HWMOD reset to fail for dss_dispc and dss_rfbi. The common reset function will also allow us to fix another problem in the future: before doing a reset we need to disable DSS outputs, which are in some cases enabled by the bootloader, as otherwise DSS HW seems to get more or less stuck, requiring a power reset to recover.

Thus if the bootloader has enabled a display, the hwmod code cannot reset the DISPC module just like that, but the outputs need to be disabled first. Add function dispc_disable_outputs() which disables all active overlay manager and ensure all frame transfers are completed. Modify omap_dss_reset() to call this function and clear DSS_CONTROL, DSS_SDI_CONTROL and DSS_PLL_CONTROL so that DSS is in a clean state when the DSS2 driver starts. This resolves the hang issue(caused by a L3 error during boot) seen on the beagle board C3, which has a factory bootloader that enables display. The issue is resolved with this patch.

This can cause normal, non-cacheable writes to be retained when the memory system is idle, leading to suboptimal I/O performance for drivers using coherent DMA. This patch adds an optional wmb() call to the cpu_idle loop. On systems with an outer cache, this causes an explicit flush of the store buffer.

The fix is to only register the notifier when initializing the first GIC, as the power management functions seem to iterate over all the registered GICs. Tested on PB11MP and PB1176.

However, it also introduced a new problem where the rates selected in .config would not take affect as omap1_select_table_rate currently refuses to reprogram DPLL1 if it's already initialized. This was not a problem earlier, as the reprogramming was done earlier with ck_dpll1_p->rate uninitialized. Fix this by forcing the reprogramming on systems booting at rates below 60MHz. Note that the long term fix is to make the rates SoC specific later on. Thanks for Janusz Krzysztofik for figuring this one out.

OTOH, in omap1_defconfig we currently rely on Kconfig options for the supported MHz rates in case of boards which boot with dpll1 not set correctly by their boot loaders. This means that before we allow for reprogramming of dpll1 rate, we should remove all unsafe clock selections from omap1_defconfig, otherwise it will stop booting on boards with imperfect boot loaders, as it would always try to change to 216MHz. Keep only one safe clock rate per each supported xtal frequency, i.e. 60MHZ dpll1 for 12MHz xtal and 182MHz dpll1 for 13MHz xtal. BTW, this change goes into the direction of removing all OMAP1 clock rate options, planned for next merge window.

Commit 48519f0ae03bc7e86b3dc93e56f1334d53803770 (ASoC: davinci: let platform data define edma queue numbers) had a side-effect of changing this behavior by making the driver actually honor the platform data passed. Fix this now by passing event queue 0 as the queue to be used for audio transfers.
